Description

Technical Field

[0001] This invention relates to the field of pipeline design technology, and more specifically, to an application-based pipeline layout structure design system and method. Background Technology

[0002] In the process of designing and modifying existing downhole vacuum pump systems, there is usually a lack of systematic analysis methods for existing pipeline connections, control valve layout and fluid delivery path. The key structural limiting factors affecting the remote switching of vacuum pumps are not fully identified, which leads to pipeline modification relying heavily on experience judgment. This can easily result in problems such as poor structural adaptability, unreasonable modification schemes and inaccurate control node settings, thus affecting the reliable realization of the remote switching function.

[0003] Meanwhile, when designing the switching between multiple vacuum pump units, existing technologies often fail to conduct an overall optimization analysis of the switching path, making it difficult to identify the key modification locations and implementation conditions that are optimal or meet the requirements for remote switching. This results in excessively large pipeline modification areas or redundant modification paths, which not only increases construction complexity but also causes low utilization of existing pipeline resources and high modification costs.

[0004] Existing vacuum pump systems generally rely on manual on-site operation to complete valve switching and equipment start-up and shutdown control. They lack a design mechanism that effectively corresponds and links remote control devices with the vacuum pump's operating status. There is insufficient coordination between pipeline status adjustment and equipment start-up and shutdown control. They cannot automatically complete fluid delivery path switching according to operating needs. They have the defects of excessive manual intervention, low degree of automation, low operating efficiency, and high risk of human error.

[0005] In addition, existing technologies often lack complete control logic, action sequence management and status determination mechanisms during vacuum pump switching. There is a lack of unified coordination and logical constraints between various control actions, which can easily lead to problems such as incorrect valve action sequence, incomplete pipeline switching, and mismatch between equipment operating status and pipeline status. This can result in switching failure, abnormal equipment operation, decreased system operation continuity and insufficient overall control reliability.

[0006] Furthermore, existing technologies often lack comprehensive verification and optimization methods for the compatibility of pipeline modification design and control strategy design, making it difficult to promptly identify potential structural conflicts, control conflicts, and operational risks. This results in repeated debugging or even secondary modifications after the implementation of the solution, which is not conducive to the long-term stable operation of the system.

[0007] In view of this, the present invention proposes an application-based pipeline layout structure design system and method to solve the above problems. Summary of the Invention

[0008] To overcome the aforementioned deficiencies of the prior art and to achieve the above objectives, the present invention provides the following technical solution: an application-based pipeline layout structure design system, comprising:

[0009] The pipeline analysis module is used to analyze the existing pipeline structure of the downhole vacuum pump unit, obtain pipeline connection information, control valve arrangement information and fluid delivery path information, identify the structural limiting positions that affect the remote switching of the vacuum pump, and form pipeline structure information.

[0010] The switching analysis module is used to analyze the switching paths between different vacuum pump units based on pipeline structure information, and to determine the pipeline modification locations and modification constraints that meet the requirements for remote switching.

[0011] The modification design module is used to configure remote control components according to the location and constraints of pipeline modification, establish the correspondence between the remote control components and the operating status of the vacuum pump, and form a pipeline modification plan.

[0012] The control orchestration module is used to construct the control logic, action sequence and status judgment rules for the vacuum pump switching process based on the pipeline modification plan, and form a remote switching control scheme.

[0013] The verification and optimization module is used to jointly verify the pipeline modification scheme and the remote switching control scheme, and to adjust and optimize them based on the verification results, outputting a pipeline layout structure design scheme for remote automatic switching of vacuum pumps.

[0014] Preferably, the method for analyzing the existing piping structure of the downhole vacuum pump unit includes:

[0015] Collect pipeline construction data corresponding to the downhole vacuum pump unit, specifically including pipeline installation data, equipment connection data, and valve configuration data;

[0016] Based on the pipeline construction data, the pipelines, control valves, connecting devices and vacuum pump units are identified as nodes. The pipeline topology is constructed based on the connection relationship between each node, and then the connection relationship between each vacuum pump unit and the main pipeline, branch pipelines and common busbars is determined, forming pipeline connection information.

[0017] Based on the location, installation direction, and driving method of the control valves in the pipeline topology, a control valve distribution mapping relationship is established to form control valve layout information;

[0018] Using the inlet and outlet ends of each vacuum pump unit as the starting and ending points of the fluid transport path, the flow direction of the fluid medium in the pipeline topology is traced to form fluid transport path information.

[0019] Preferably, the method for obtaining the pipeline structure information includes:

[0020] Based on pipeline connectivity information, control valve layout information, and fluid delivery path information, a switching path between each vacuum pump unit is constructed. Based on preset remote switching conditions, each switching path is analyzed segment by segment to determine whether there are structural limiting locations that affect the remote switching of the vacuum pump. Among these structural limiting locations, there are manual intervention limiting locations, flow direction control limiting locations, switching channel limiting locations, switching conflict limiting locations, and equipment installation limiting locations. The limiting type, location, and associated paths corresponding to each structural limiting location are integrated to form pipeline structure information.

[0021] Preferably, the method for determining the pipeline modification location and modification constraints that meet the remote switching requirements includes:

[0022] Based on the correlation between each structural constraint location and the corresponding pipes, control valves and connecting devices in the pipeline structure information, the target pipeline units directly associated with the structural constraint locations are identified; the target pipeline units are classified and identified according to the structural constraint type, and the corresponding pipeline modification locations are determined.

[0023] Specifically, when the structural constraint type of the target pipeline unit is the manual intervention constraint type, the corresponding control valve will be marked as the control automation modification location; when the structural constraint type of the target pipeline unit is the flow direction control constraint type, the corresponding pipeline connection location will be marked as the flow direction control modification location.

[0024] When the structural constraint type of the target piping unit is a switching conflict constraint type, the corresponding shared connection node will be marked as a switching isolation modification location; when the structural constraint type of the target piping unit is an equipment installation constraint type, the corresponding installation area will be marked as a structural optimization modification location.

[0025] Based on the pipeline connectivity and fluid transport path information corresponding to each pipeline modification location, the modification constraints that each modification location needs to meet are determined. These constraints include control automation constraints, flow direction control constraints, switching channel independence constraints, switching isolation constraints, and installation adaptation constraints.

[0026] The control automation constraint is used to ensure that the corresponding control node has remote execution capability; the flow direction control constraint is used to ensure that the fluid medium is delivered in the preset direction and there is no risk of backflow; the switching channel independence constraint is used to ensure that independent switching channels are formed between different vacuum pump units; the switching isolation constraint is used to ensure that non-target paths can be effectively isolated during the switching process; and the installation adaptation constraint is used to ensure that remote control components can be installed and connected at the corresponding modification location.

[0027] Preferably, the method for configuring remote control components based on the pipeline modification location and modification constraints includes:

[0028] Based on the structural constraint type and modification constraints corresponding to each pipeline modification location, determine the remote control function to be implemented after modification, select the corresponding remote control component from the preset remote control component library according to the remote control function, and establish the configuration relationship between the remote control component and the corresponding pipeline modification location.

[0029] Based on the configuration relationship between each remote control component and the corresponding pipeline modification location, the connectivity status of the modified pipeline is verified. When all configured remote control components meet the corresponding modification constraints, the configuration result of the remote control components is obtained.

[0030] Preferably, the method for forming the pipeline modification scheme includes:

[0031] Based on the configuration relationship between the remote control components and the corresponding pipeline modification locations, the installation location, control object, control range, and associated fluid delivery path of each remote control component are obtained; the vacuum pump operating status is divided according to the operating requirements of the vacuum pump unit, including operating status, standby status, and switching status.

[0032] Based on the connectivity and isolation requirements of the corresponding fluid transport paths under each operating state, determine the target action state of each remote control component under the corresponding operating state, and establish the correspondence between the vacuum pump operating state and the target action state of the remote control component.

[0033] Specifically, when the vacuum pump unit is in operation, the remote control component on the corresponding fluid delivery path is in the on state; when the vacuum pump unit is in standby state, the remote control component on the corresponding standby fluid delivery path is in the isolated state; when the vacuum pump unit is in switching state, the remote control component is controlled to perform opening and closing actions according to the preset switching sequence.

[0034] The configuration relationship between each remote control component and the corresponding pipeline modification location, the target action status, and the vacuum pump operation status are linked and integrated to form a pipeline modification plan.

[0035] Preferably, the method for obtaining the remote switching control scheme includes:

[0036] Based on the installation location, control object, control range, and correspondence between the remote control components and the vacuum pump operating status of each remote control component in the pipeline modification scheme, the control dependency relationship between each remote control component is determined, and the switching control link corresponding to the vacuum pump switching process is constructed.

[0037] Based on the changing relationship between the fluid delivery path corresponding to the operating vacuum pump before switching and the fluid delivery path corresponding to the target vacuum pump after switching, determine the path isolation operation, path connection operation and operating state conversion operation involved in the switching process;

[0038] The switching control logic is constructed according to the execution principle that path isolation takes precedence over path switching, and path switching takes precedence over path connection; based on the switching control link and the switching control logic, the execution order of each remote control component is determined, and the corresponding switching action sequence is generated.

[0039] Based on the target action status, feedback status, and connectivity status of the corresponding fluid delivery path of each remote control component, establish a status judgment rule corresponding to the switching action sequence; when the isolation control component of the corresponding path reaches the target isolation status, the path isolation is determined to be complete; when the control component corresponding to the target delivery path reaches the target conduction status, the target path conduction is determined to be complete.

[0040] When each action in the switching sequence meets the corresponding state determination rule, the vacuum pump switching is determined to be complete; the switching control logic, switching sequence, and state determination rule are linked and integrated to form a remote switching control scheme.

[0041] Preferably, the method for jointly verifying the pipeline modification scheme and the remote switching control scheme includes:

[0042] Based on the configuration relationship of remote control components in the pipeline modification scheme and the pipeline connection relationship after modification, the connection status between each vacuum pump unit is simulated and set, and the control logic, action sequence and status judgment rules in the remote switching control scheme are loaded into the simulation execution process as the execution basis.

[0043] The control actions of each remote control component are executed sequentially according to the remote switching control scheme, and the connection status of the corresponding pipeline is updated synchronously to simulate the vacuum pump switching process; the pipeline connection status obtained during the simulation is compared with the control action execution results to determine whether there are any situations where the pipeline cannot be completely isolated, the target path cannot be connected, or the control action sequence is abnormal.

[0044] The action feedback status of each remote control component is verified by combining the status judgment rules to determine whether the preset target action status is met. When both the consistency comparison result and the status verification result meet the preset conditions, the joint verification is deemed to have passed; otherwise, the joint verification is deemed to have failed, and the corresponding abnormal position is output.

[0045] Preferably, the method for adjusting and optimizing the pipeline layout structure design scheme for remote automatic switching of vacuum pumps based on verification results includes:

[0046] The joint verification results are classified and processed, including verification pass results and verification fail results; when the verification is passed, it is determined that the pipeline modification scheme and the remote switching control scheme meet the preset path connectivity, path isolation integrity and control action sequence requirements.

[0047] When the verification fails, the abnormal location is located and analyzed based on the pipeline connectivity status change information, remote control component action feedback information and status judgment results recorded during the verification process, and the abnormality type is classified as path isolation abnormality, path continuity abnormality or control sequence abnormality.

[0048] The pipeline modification plan or remote switching control plan is adjusted and optimized according to the type of anomaly. Specifically, when the anomaly type is a path isolation anomaly, the configuration of the remote control component at the corresponding pipeline modification location is adjusted to enhance the path isolation capability.

[0049] When the anomaly type is path connectivity anomaly, the configuration or connection relationship of the control components on the target delivery path is corrected to ensure path connectivity. When the anomaly type is control sequence anomaly, the control logic and action sequence in the remote switching control scheme are rearranged.

[0050] The adjusted and optimized pipeline modification scheme and remote switching control scheme are re-verified globally until the preset verification conditions are met. The pipeline modification scheme and remote switching control scheme that finally meet the verification conditions are integrated to output the pipeline layout structure design scheme for remote automatic switching of vacuum pump.

[0051] Application-based piping layout design methods include:

[0052] S1. Analyze the existing pipeline structure of the downhole vacuum pump unit to obtain pipeline connection information, control valve arrangement information and fluid delivery path information, identify the structural limiting positions that affect the remote switching of the vacuum pump, and form pipeline structure information.

[0053] S2. Based on the pipeline structure information, analyze the switching paths between different vacuum pump units, and determine the pipeline modification locations and modification constraints that meet the remote switching requirements.

[0054] S3. Configure remote control components according to the location and constraints of pipeline modification, establish the correspondence between remote control components and vacuum pump operating status, and form a pipeline modification plan.

[0055] S4. Based on the pipeline modification plan, construct the control logic, action sequence and status judgment rules for the vacuum pump switching process to form a remote switching control scheme.

[0056] S5. Jointly verify the pipeline modification scheme and the remote switching control scheme, and adjust and optimize them according to the verification results, and output the pipeline layout structure design scheme for remote automatic switching of vacuum pump.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] By comprehensively analyzing the connectivity, control element layout, and fluid delivery path of the existing pipeline structure of the downhole vacuum pump unit, the key structural limiting factors and control nodes affecting the remote switching of the vacuum pump can be accurately identified. This allows the pipeline modification to be based on the existing system structural characteristics, avoiding modification failures, functional conflicts, or resource waste caused by insufficient understanding of the structure, thereby improving the scientificity and accuracy of the pipeline layout design.

[0059] By analyzing the switching paths between different vacuum pump units, the key modification locations and implementation conditions that meet the requirements for remote switching can be identified. The switching function can be upgraded while preserving the original pipeline structure to the greatest extent, reducing large-scale dismantling and duplication of construction, thereby reducing the difficulty of project implementation and modification costs, and improving the utilization rate and economy of the existing system.

[0060] By establishing a correspondence between the remote control device and the vacuum pump's operating status, a coordinated linkage mechanism is formed between pipeline status adjustment and vacuum pump start-stop control. The system can automatically switch fluid delivery paths according to operational needs, reducing the frequency of personnel entering the site to operate valves and switch equipment. This not only improves production management efficiency but also helps reduce the intensity of manual operation and the risk of human error.

[0061] Further constructing the action execution sequence, control logic, and state judgment rules during the vacuum pump switching process will create a clear sequential relationship and logical constraints between each control action. This will effectively avoid problems such as valve mis-opening or closing, abnormal pipeline connectivity, equipment no-load operation, or load impact during the switching process, ensuring a smooth and orderly switching process and improving the continuity of vacuum pump operation and the reliability of system control.

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0065] Please see Figure 1 As shown, this embodiment provides an application-based pipeline layout structure design system, which specifically includes the following steps:

[0066] The pipeline analysis module is used to analyze the existing pipeline structure of the downhole vacuum pump unit, obtain pipeline connection information, control valve arrangement information and fluid delivery path information, identify the structural limiting positions that affect the remote switching of the vacuum pump, and form pipeline structure information.

[0067] The switching analysis module is used to analyze the switching paths between different vacuum pump units based on pipeline structure information, and to determine the pipeline modification locations and modification constraints that meet the requirements for remote switching.

[0068] The modification design module is used to configure remote control components according to the location and constraints of pipeline modification, establish the correspondence between the remote control components and the operating status of the vacuum pump, and form a pipeline modification plan.

[0069] The control orchestration module is used to construct the control logic, action sequence and status judgment rules for the vacuum pump switching process based on the pipeline modification plan, and form a remote switching control scheme.

[0070] The verification and optimization module is used to jointly verify the pipeline modification scheme and the remote switching control scheme, and to adjust and optimize them based on the verification results, outputting a pipeline layout structure design scheme for remote automatic switching of vacuum pumps.

[0071] Methods for analyzing the existing piping structure of downhole vacuum pump units include:

[0072] Collect pipeline construction data corresponding to the downhole vacuum pump unit, specifically including pipeline installation data, equipment connection data, and valve configuration data;

[0073] It should be noted that: pipeline installation data includes the installation location, connection method, pipe diameter specifications, and pipeline route of each pipeline in the well; equipment connection data includes the connection relationship between the vacuum pump unit and the main pipeline, branch pipelines, and auxiliary equipment; valve configuration data includes the installation location, control valve type, drive method, and valve opening and closing status of the control valves.

[0074] Based on the pipeline construction data, the pipelines, control valves, connecting devices and vacuum pump units are identified as nodes. The pipeline topology is constructed based on the connection relationship between each node, and then the connection relationship between each vacuum pump unit and the main pipeline, branch pipelines and common busbars is determined, forming pipeline connection information.

[0075] Specifically: The collected pipeline construction data is formatted in a unified manner, and the pipes, control valves, connecting devices and vacuum pump units are numbered and identified to form a pipeline construction dataset for subsequent structural analysis;

[0076] Based on the pipeline construction dataset, nodes are identified for pipes, control valves, connecting devices, and vacuum pump units; specifically, the pipeline topology is constructed by using control valves, connecting devices, and vacuum pump units as nodes and connecting pipes between nodes as connecting edges.

[0077] By traversing the connection status between each node in the pipeline topology, the connection relationship between each vacuum pump unit and the main pipeline, branch pipeline and common bus pipeline is determined, and the upstream and downstream correspondence between each pipeline and the pipeline range that each vacuum pump unit can reach are obtained, thus forming pipeline connectivity information.

[0078] Based on the location, installation direction, and driving method of the control valves in the pipeline topology, a control valve distribution mapping relationship is established to form control valve layout information;

[0079] The installation direction is used to determine the permissible flow direction of the fluid medium in the pipeline for the control valve; the drive method is used to characterize the control method corresponding to the control valve, such as manual control valve, electric control valve, pneumatic control valve or other valves that can be remotely controlled; by establishing the correspondence between the control valve and adjacent pipelines, the influence range of each control valve on the pipeline connection state and the fluid medium flow direction switching process is determined, thereby forming the control valve layout information.

[0080] Using the inlet and outlet ends of each vacuum pump unit as the starting and ending points of the fluid transport path, the flow direction of the fluid medium in the pipeline topology is traced to form fluid transport path information.

[0081] Specifically, the inlet end of each vacuum pump unit is taken as the starting point of the fluid delivery path, and the outlet end is taken as the ending point of the fluid delivery path. Combining the connection relationship between each node in the pipeline topology and the installation direction of the control valve, the flow direction of the fluid medium in the pipeline is traced to obtain the pipes, control valves, connecting devices, and fluid medium flow direction that the fluid medium passes through from the inlet end to the outlet end. If there are multiple branch paths in the fluid delivery path, the pipes, control valves, and connecting devices passed through each branch path are counted separately, and the fluid medium flow direction corresponding to each branch path is recorded. The pipes, control valves, and connecting devices passed through by each fluid delivery path are arranged in chronological order and associated with the corresponding fluid medium flow direction to form fluid delivery path information.

[0082] For example: Suppose that there is a first vacuum pump unit P1 and a second vacuum pump unit P2 installed downhole, and the two vacuum pumps share the same main pipeline.

[0083] The inlet of the first vacuum pump unit P1 is connected to the common manifold via pipe L1, and the outlet is connected to the main pipeline via control valve V1, pipe L2 and control valve V2 in sequence.

[0084] The inlet of the second vacuum pump unit P2 is also connected to the common manifold, and the outlet is connected to the main pipeline in sequence through control valve V3, pipeline L3 and control valve V4.

[0085] Meanwhile, a connecting device J1 and a bypass pipe L4 are installed between pipe L2 and pipe L3 to enable switching between the two vacuum pumps.

[0086] After the pipeline topology is constructed, the inlet end of the first vacuum pump unit P1 is taken as the starting point of the path, and the outlet end of the first vacuum pump unit P1 is taken as the ending point of the path. Based on the installation direction of control valves V1 and V2 and the connection relationship between each node, path tracing is performed to determine the fluid delivery path 1 as: P1 inlet end → pipeline L1 → first vacuum pump unit P1 → control valve V1 → pipeline L2 → control valve V2 → main pipeline. Based on this, the pipelines, control valves, connecting devices and fluid medium flow direction along the fluid delivery path 1 can be obtained.

[0087] Furthermore, if a branch path is found to be formed between the bypass pipe L4 and the connecting device J1 during the path tracing process, the branch path identification continues. For example, the fluid medium can also flow along the following fluid transport path 2: P1 inlet end → pipe L1 → first vacuum pump unit P1 → control valve V1 → pipe L2 → connecting device J1 → bypass pipe L4 → pipe L3 → control valve V4 → main pipe; at this time, the system records the pipes, control valves and connecting devices traversed by the main path and the branch path respectively, and records the corresponding fluid medium flow direction.

[0088] Subsequently, the identified fluid delivery paths are structured and arranged, and the components of each fluid delivery path are associated with the corresponding fluid medium flow direction and stored, thus forming fluid delivery path information. This fluid delivery path information not only reflects the specific path the fluid medium takes from the inlet to the outlet, but also characterizes the connection and flow direction relationships between the branch paths, providing a foundation for subsequent identification of vacuum pump switching channels, analysis of switching feasibility, and determination of the installation location of remote control components.

[0089] In this embodiment, the fluid transport path information is specifically represented as follows:

[0090] Route 1: (L1→P1→V1→L2→V2→Main Line) + (Common Busway→Main Line)

[0091] Route 2: (L1→P1→V1→L2→J1→L4→L3→V4→Main Line) + (Common Busway→Bypass Line→Main Line)

[0092] Methods for obtaining pipeline structure information include:

[0093] Based on pipeline connectivity information, control valve layout information, and fluid delivery path information, a switching path between each vacuum pump unit is constructed. Based on preset remote switching conditions, each switching path is analyzed segment by segment to determine whether there are structural limiting locations that affect the remote switching of the vacuum pump. Among these structural limiting locations, there are manual intervention limiting locations, flow direction control limiting locations, switching channel limiting locations, switching conflict limiting locations, and equipment installation limiting locations. The limiting type, location, and associated paths corresponding to each structural limiting location are integrated to form pipeline structure information.

[0094] Specifically: Based on pipeline connectivity information, the switching paths between vacuum pump units in the existing pipeline structure are identified, and based on the control valve arrangement information, it is further determined whether the control valves on each switching path have remote execution capabilities. At the same time, the fluid transport path information is combined to analyze the fluid medium transport direction and isolation relationship corresponding to each switching path. Among them, the switching path is a set of connectable paths consisting of the inlet end and outlet end of the vacuum pump unit and the main pipeline, branch pipeline and common manifold connected to it.

[0095] It should be noted that the preset remote switching conditions include control automation conditions, flow direction controllable conditions, independent switching conditions, switching safety conditions, and installation feasibility conditions. Among them, the control automation condition requires that each node on the switching path has remote execution capability; the flow direction controllable condition requires that the fluid medium can flow in the predetermined delivery direction without the risk of backflow; the independent switching condition requires that different vacuum pump units have independent switching channels; the switching safety condition requires that there are no situations where multiple vacuum pump units are simultaneously connected or simultaneously disconnected during the switching process; and the installation feasibility condition requires that the pipeline system has the conditions for the installation and connection of remote control components.

[0096] Based on this, the components of each switching path are analyzed segment by segment in sequence, and the pipes, control valves, connecting devices, etc. contained in the switching path are judged in turn to identify whether there are structural restriction positions that do not meet the preset remote switching conditions.

[0097] The structural restriction locations include manual intervention restriction locations, flow direction control restriction locations, switching channel restriction locations, switching conflict restriction locations, and equipment installation restriction locations. Specifically, nodes that require manual intervention to complete the operation are marked as manual intervention restriction locations; pipeline locations where there is a risk of fluid medium backflow during vacuum pump unit switching are marked as flow direction control restriction locations; connection locations where different vacuum pump units cannot form independent switching channels are marked as switching channel restriction locations; nodes that may cause multiple vacuum pumps to connect or disconnect simultaneously during switching are marked as switching conflict restriction locations; and areas with insufficient installation space, incompatible interface types, or where remote control devices cannot be directly added are marked as equipment installation restriction locations.

[0098] Subsequently, the structural restriction locations that do not meet the preset remote switching conditions are summarized, and the restriction type and location in the switching path are recorded. At the same time, the corresponding control valves, pipelines and fluid delivery path information are associated. The restriction types include factors such as insufficient control automation, incomplete fluid delivery path, lack of switching isolation conditions and limited equipment installation conditions.

[0099] Finally, the structural constraint locations identified in each switching channel path, along with their corresponding constraint types, location attributes, and relationships, are uniformly summarized to form pipeline structure information that characterizes the remote switching capability of the existing downhole vacuum pump unit pipeline system. This provides a basis for subsequent pipeline modification design and remote control strategy configuration.

[0100] Methods for determining the location and constraints of pipeline modifications that meet remote switching requirements include:

[0101] Based on the relationship between each structural constraint position and the corresponding pipe, control valve and connecting device in the pipeline structure information, the target pipeline unit directly associated with the structural constraint position is determined.

[0102] In this embodiment, it should be noted that the target pipeline unit is the smallest functional unit that has a direct topological connection with the structural constraint location in the switching channel path, and it includes the corresponding pipeline segment, control valve node, or connecting device node. For example, when the structural constraint location corresponds to a control valve that cannot be remotely operated, the control valve and its adjacent pipeline connecting segments before and after it are taken as the target pipeline unit; when the structural constraint location corresponds to a shared pipeline connection node, the shared connection node and its multiple connected pipeline branches are taken as the target pipeline unit.

[0103] The target piping units are classified and identified according to the type of structural constraints, and the corresponding piping modification locations are determined.

[0104] Specifically, when the structural constraint type of the target pipeline unit is the manual intervention constraint type, the corresponding control valve will be marked as the control automation modification location; when the structural constraint type of the target pipeline unit is the flow direction control constraint type, the corresponding pipeline connection location will be marked as the flow direction control modification location; when the structural constraint type of the target pipeline unit is the switching conflict constraint type, the corresponding shared connection node will be marked as the switching isolation modification location; when the structural constraint type of the target pipeline unit is the equipment installation constraint type, the corresponding installation area will be marked as the structural optimization modification location.

[0105] Based on the pipeline connectivity and fluid transport path information corresponding to each pipeline modification location, the modification constraints that each modification location needs to meet are determined. These constraints include control automation constraints, flow direction control constraints, switching channel independence constraints, switching isolation constraints, and installation adaptation constraints.

[0106] The control automation constraint is used to ensure that the corresponding control node has remote execution capability; the flow direction control constraint is used to ensure that the fluid medium is delivered in the preset direction and there is no risk of backflow; the switching channel independence constraint is used to ensure that independent switching channels are formed between different vacuum pump units; the switching isolation constraint is used to ensure that non-target paths can be effectively isolated during the switching process; and the installation adaptation constraint is used to ensure that remote control components can be installed and connected at the corresponding modification location.

[0107] For example, based on the upstream and downstream connectivity of the modification location in the pipeline topology, analyze the type of node that plays a role in the fluid transport path, and determine the corresponding flow direction constraints by combining the medium flow direction relationship in the fluid transport path information; at the same time, combine the control valve layout information to determine whether the modification location needs to meet the remote execution control conditions, so as to determine the control mode matching conditions; and based on the sharing relationship of the modification location in different switching paths, determine whether it needs to meet the path isolation or independent switching conditions.

[0108] For example, if the structural constraint location in the target pipeline unit is a shared tee node connecting two branches, then this node is identified as the critical connecting unit in the target pipeline unit. Further analysis of its role in the fluid transport path reveals that this node also participates in the switching path between the first vacuum pump unit and the second vacuum pump unit, thus classifying it as a switching isolation missing type. Subsequently, based on its upstream and downstream position in the pipeline connection relationship, the modification constraints that this modification location needs to meet include: ensuring that only one path is allowed to conduct at any given time after the modification, and meeting the remote control execution conditions for linkage with adjacent control valves.

[0109] Methods for configuring remote control components based on the location and constraints of pipeline modifications include:

[0110] Based on the structural constraint type and modification constraints corresponding to each pipeline modification location, determine the remote control function to be implemented after modification, select the corresponding remote control component from the preset remote control component library according to the remote control function, and establish the configuration relationship between the remote control component and the corresponding pipeline modification location.

[0111] Based on the configuration relationship between each remote control component and the corresponding pipeline modification location, the connectivity status of the modified pipeline is verified. When all configured remote control components meet the corresponding modification constraints, the configuration result of the remote control components is obtained.

[0112] Specifically, when the pipeline modification location is a control automation modification location, an electric control valve, electromagnetic actuator, or pneumatic actuator with remote opening and closing function shall be configured; when the pipeline modification location is a flow direction control modification location, a check valve or one-way control device with one-way flow direction function shall be configured.

[0113] When the pipeline modification location is a switching channel modification location, a switching control valve or diversion control device is configured to establish an independent switching channel; when the pipeline modification location is a switching isolation modification location, an isolation control valve or interlock control device is configured; when the pipeline modification location is a structural optimization modification location, an interface conversion component, installation support component or modular connection component is configured.

[0114] In this embodiment, after determining the type of remote control component, the configuration relationship between the remote control component and the corresponding pipeline modification location is further established to clarify the installation object, control object and scope of each remote control component in the modified pipeline system, so as to provide a basis for subsequent operation status mapping and switching control logic construction.

[0115] Match the control functions of the selected remote control components with the modification requirements of the pipeline modification locations to establish a one-to-one or one-to-many correspondence between the remote control components and the corresponding pipeline modification locations. A one-to-one correspondence means that one remote control component is configured for one pipeline modification location. A one-to-many correspondence means that multiple remote control components are required to work together to complete the control functions for one pipeline modification location.

[0116] Methods for developing pipeline modification plans include:

[0117] Based on the configuration relationship between the remote control components and the corresponding pipeline modification locations, the installation location, control object, control range, and associated fluid delivery path of each remote control component are obtained; the vacuum pump operating status is divided according to the operating requirements of the vacuum pump unit, including operating status, standby status, and switching status.

[0118] Based on the connectivity and isolation requirements of the corresponding fluid transport paths under each operating state, determine the target action state of each remote control component under the corresponding operating state, and establish the correspondence between the vacuum pump operating state and the target action state of the remote control component.

[0119] Specifically, when the vacuum pump unit is in operation, the remote control component on the corresponding operating fluid delivery path is in the on state; when the vacuum pump unit is in standby state, the remote control component on the corresponding standby fluid delivery path is in the isolated state; when the vacuum pump unit is in switching state, the remote control component is controlled to perform opening and closing actions according to the preset switching sequence to realize the switching between the operating fluid delivery path and the target fluid delivery path.

[0120] The configuration relationship between each remote control component and the corresponding pipeline modification location, the target action status, and the vacuum pump operation status are linked and integrated to form a pipeline modification plan.

[0121] Methods for obtaining remote switching control schemes include:

[0122] Based on the installation location, control object, control range, and correspondence between the remote control components and the vacuum pump operating status of each remote control component in the pipeline modification scheme, the control dependency relationship between each remote control component is determined, and the switching control link corresponding to the vacuum pump switching process is constructed.

[0123] It should be noted that the installation location is used to determine the position of the remote control component in the pipeline topology; the controlled object is used to determine the pipeline, connection channel, or vacuum pump branch controlled by the remote control component; the control range is used to determine the fluid delivery area affected by the action of the remote control component; and the operating state correspondence is used to determine the target actions that the remote control component should perform under different operating states. Subsequently, based on the upstream and downstream relationships of each remote control component in the fluid delivery path and the influence relationships between the control ranges, the control dependencies between the remote control components are determined.

[0124] Specifically, when the action result of one remote control component affects the conduction condition of the corresponding path of another remote control component, the former is identified as the preceding control node of the latter; when one remote control component completes its action before the other remote control component can execute its corresponding control action, a control dependency relationship is established between the two. After the dependency relationship is identified, each remote control component is sequentially associated according to the control dependency relationship to form the switching control link corresponding to the vacuum pump switching process.

[0125] Based on the changing relationship between the fluid delivery path corresponding to the operating vacuum pump before switching and the fluid delivery path corresponding to the target vacuum pump after switching, determine the path isolation operation, path connection operation and operating state conversion operation involved in the switching process;

[0126] Specifically, the fluid delivery path corresponding to the currently operating vacuum pump is determined as the original path, and the fluid delivery path corresponding to the target vacuum pump is determined as the target path. A path comparison analysis is then performed on the two paths. Based on the path comparison results, the following are identified: the original path segments that need to be disconnected; the target path segments that need to be established; and the common connection segments that need to be kept isolated.

[0127] Subsequently, the types of operations involved in the switching process were determined based on the control requirements corresponding to each section. Among them: the operation used to disconnect the original path from the common manifold was determined to be a path isolation operation; the operation used to establish the connection between the target path and the common manifold was determined to be a path connection operation; and the operation used to complete the role switch between the running vacuum pump and the target vacuum pump was determined to be an operating state switch operation.

[0128] The switching control logic is constructed according to the execution principle that path isolation takes precedence over path switching, and path switching takes precedence over path connection; based on the switching control link and the switching control logic, the execution order of each remote control component is determined, and the corresponding switching action sequence is generated.

[0129] Specifically, the control logic is established according to the execution order of: path isolation operation → path switching operation → path connection operation. Among them: the path isolation operation is executed first to eliminate the connection between the original running path and the system; the path switching operation is executed next to complete the control state adjustment of the switching channel; and the path connection operation is executed last to establish the target delivery path.

[0130] Based on the control dependencies of each remote control component in the switching control link, the execution order of each remote control component is determined. For remote control components with preceding control relationships, the actions corresponding to the preceding control nodes are executed first; after the preceding control node's actions are completed, the subsequent control node's actions are executed. Then, the control actions corresponding to each remote control component are arranged in the execution order to form a complete switching action sequence.

[0131] Based on the target action status, feedback status, and connectivity status of the corresponding fluid delivery path of each remote control component, establish a status judgment rule corresponding to the switching action sequence; when the isolation control component of the corresponding path reaches the target isolation status, the path isolation is determined to be complete; when the control component corresponding to the target delivery path reaches the target conduction status, the target path conduction is determined to be complete.

[0132] After generating the switching action sequence, state determination rules corresponding to the switching action sequence are further established. Specifically, state determination conditions for each step are constructed based on the target action state, feedback state, and connectivity state of the corresponding fluid transport path for each remote control component.

[0133] Specifically: when the feedback status of the remote control component is consistent with the target action status, the corresponding control action is determined to be completed; when the corresponding fluid delivery path reaches the expected connection state, the corresponding path control is determined to be completed; when the status judgment condition corresponding to a certain action is met, the next control action is allowed to be executed; when all actions in the switching action sequence meet the corresponding status judgment conditions, the vacuum pump switching is determined to be completed.

[0134] When each action in the switching sequence meets the corresponding state determination rule, the vacuum pump switching is determined to be complete; the switching control logic, switching sequence, and state determination rule are linked and integrated to form a remote switching control scheme.

[0135] For example, the first vacuum pump is the currently operating vacuum pump, and the second vacuum pump is the standby vacuum pump. An electric control valve A1 is installed on the delivery path corresponding to the first vacuum pump, and an electric control valve B1 is installed on the delivery path corresponding to the second vacuum pump. An isolation control valve C1 is installed at the common connection point of the two paths.

[0136] During the switching process, the analysis first revealed that: electric control valve A1 controls the original operating path; electric control valve B1 controls the target path; and isolation control valve C1 controls the common connection area. Therefore, it was determined that the action result of isolation control valve C1 would affect whether the corresponding path of electric control valve B1 could be safely connected, thus establishing the control dependency relationship of C1→B1.

[0137] Simultaneously, the original path exit can only be completed after the electric control valve A1 is closed. Therefore, a switching control link is established: A1→C1→B1. Subsequently, based on the path change relationship, it is determined that: closing the electric control valve A1 is a path isolation operation; adjusting the isolation control valve C1 is a path switching operation; and opening the electric control valve B1 is a path connection operation.

[0138] Based on the preset execution principle, the following switching control logic is formed: first turn off A1 → then switch C1 → then turn on B1.

[0139] The following switching sequence is generated: Step 1: Close the electric control valve A1; Step 2: Confirm that the electric control valve A1 has been closed; Step 3: Switch the isolation control valve C1 to the target state; Step 4: Confirm that the isolation control valve C1 has been opened; Step 5: Open the electric control valve B1; Step 6: Confirm that the electric control valve B1 has been opened.

[0140] The corresponding status determination rules are as follows: when the electric control valve A1 sends a closed signal, the original path isolation is determined to be complete; when the isolation control valve C1 sends a position signal, the switching channel is determined to be established; when the electric control valve B1 sends an open signal, the target path is determined to be connected; when all three determination conditions are met, the vacuum pump switching is determined to be complete. Through this method, remote automatic switching from the first vacuum pump to the second vacuum pump is achieved.

[0141] The methods for jointly verifying pipeline modification schemes and remote switching control schemes include:

[0142] Based on the configuration relationship of remote control components in the pipeline modification scheme and the pipeline connection relationship after modification, the connection status between each vacuum pump unit is simulated and set, and the control logic, action sequence and status judgment rules in the remote switching control scheme are loaded into the simulation execution process as the execution basis.

[0143] The process of simulating and setting the connectivity status between each vacuum pump unit involves: initializing the connectivity status between each vacuum pump unit based on the modified pipeline connectivity, and converting the connection relationship between each vacuum pump unit and its corresponding pipeline node into a representable connectivity status data structure. Based on the operational range of the remote control component in the pipeline system, the connectivity status is dynamically updated and simulated. Specifically, when the remote control component is in the on state, the connectivity relationship between the corresponding pipeline nodes is maintained; when the remote control component is in the off state, the connectivity relationship between the corresponding pipeline nodes is severed; when the remote control component is in the switching process, the corresponding connectivity status is adjusted in stages according to its action phase, thus forming the connectivity status change process between each vacuum pump unit at different switching stages.

[0144] The control actions of each remote control component are executed sequentially according to the remote switching control scheme, and the connection status of the corresponding pipeline is updated synchronously to simulate the vacuum pump switching process; the pipeline connection status obtained during the simulation is compared with the control action execution results to determine whether there are any situations where the pipeline cannot be completely isolated, the target path cannot be connected, or the control action sequence is abnormal.

[0145] The action feedback status of each remote control component is verified by combining the status judgment rules to determine whether the preset target action status is met. When both the consistency comparison result and the status verification result meet the preset conditions, the joint verification is deemed to have passed; otherwise, the joint verification is deemed to have failed, and the corresponding abnormal position is output.

[0146] Based on the target action status, actual feedback status, and corresponding pipeline connectivity status of each remote control component, multi-dimensional verification conditions are established. The target action status characterizes the control state that the remote control component should achieve under its current operating conditions; the feedback status characterizes the status return information after the remote control component's actual execution; and the connectivity status characterizes whether the corresponding pipeline is in a conductive or isolated state.

[0147] Subsequently, the consistency between the target action state and the feedback state is compared. When the feedback state is consistent with the target action state, the action of the remote control component is deemed to be valid; when the feedback state is inconsistent with the target action state, the action of the remote control component is deemed to be abnormal.

[0148] Furthermore, the verification results are constrained by the corresponding pipeline connectivity status. For example, when the target action is closed, the corresponding pipeline should be in an isolated state; when the target action is open, the corresponding pipeline should be in a connected state; if the two do not match, the preset target action state is determined not to be met. Finally, the above verification process is used to determine whether each remote control component meets the preset state judgment conditions, thereby determining whether the joint verification is valid.

[0149] For example, the first vacuum pump unit and the second vacuum pump unit are connected via a common manifold. In the pipeline modification scheme, an electrically controlled valve A2 is installed on the outlet side of the first vacuum pump, and an electrically controlled valve B2 is installed on the inlet side of the second vacuum pump. When simulating the connection state, the connection between the two vacuum pumps and the common manifold is first initialized; when A2 is in the open state, the first vacuum pump remains connected to the common manifold; when A2 is in the closed state, the connection between the first vacuum pump and the common manifold is severed.

[0150] During the switching process, according to the control logic, the system requires A2 to close first and B2 to open later. During the status verification process, it was found that when A2 feedback indicated that it was closed but the common busbar was still connected, it was determined that the component did not meet the preset target action state. Further inspection revealed that the control valve was not fully closed, thus determining that the control component was malfunctioning and that the control parameters needed to be readjusted or the control component needed to be replaced.

[0151] The method for adjusting and optimizing the pipeline layout structure design scheme for remote automatic switching of vacuum pumps based on the verification results includes:

[0152] The joint verification results are classified and processed, including verification pass results and verification fail results; when the verification is passed, it is determined that the pipeline modification scheme and the remote switching control scheme meet the preset path connectivity, path isolation integrity and control action sequence requirements.

[0153] The preset path connectivity requirement is used to verify whether the target vacuum pump unit can form a complete fluid delivery path after switching. Specifically, this includes: the fluid delivery path between the inlet and outlet of the target vacuum pump unit remains continuously connected, the control valves, connecting devices, and related pipelines on the path are all in a state that allows the fluid medium to pass through, and there is no disconnection of the delivery path due to the closure of control valves, interruption of pipelines, or missing connections;

[0154] For example, when the first vacuum pump is switched to the second vacuum pump, the inlet pipe, outlet pipe and common manifold of the second vacuum pump should form a continuous and connected channel so that the fluid medium can be transported in the predetermined direction; if a control valve in the path of the second vacuum pump is still closed, a complete transport path cannot be formed, and the path connectivity requirement is not met.

[0155] The preset path isolation integrity requirement is used to verify whether the delivery path corresponding to the original operating vacuum pump can be effectively isolated during the switching process. Specifically, this includes: the delivery path corresponding to the non-target vacuum pump should be disconnected; there should be no unexpected connection between the original operating path and the target operating path; and there should be no cross-flow, backflow, or co-flow of fluid media.

[0156] The preset control action sequence requirement is used to verify whether the execution order of each remote control component in the remote switching control scheme conforms to the preset control logic. Specifically, this includes: each remote control component should execute in the predetermined action sequence, and the execution of subsequent actions should be based on the completion of the preceding actions and the satisfaction of the corresponding state judgment conditions. Situations such as skipping levels of control actions, executing actions ahead of time, or omitting actions are not allowed.

[0157] When the verification fails, the abnormal location is located and analyzed based on the pipeline connectivity status change information, remote control component action feedback information and status judgment results recorded during the verification process, and the abnormality type is classified as path isolation abnormality, path continuity abnormality or control sequence abnormality.

[0158] The pipeline modification plan or remote switching control plan is adjusted and optimized according to the type of anomaly. Specifically, when the anomaly type is a path isolation anomaly, the configuration of the remote control component at the corresponding pipeline modification location is adjusted to enhance the path isolation capability.

[0159] When the anomaly type is path connectivity anomaly, the configuration or connection relationship of the control components on the target delivery path is corrected to ensure path connectivity. When the anomaly type is control sequence anomaly, the control logic and action sequence in the remote switching control scheme are rearranged.

[0160] The adjusted and optimized pipeline modification scheme and remote switching control scheme are re-verified globally until the preset verification conditions are met. The pipeline modification scheme and remote switching control scheme that finally meet the verification conditions are integrated to output the pipeline layout structure design scheme for remote automatic switching of vacuum pump.

[0161] Specifically, the process involves acquiring the adjusted and optimized pipeline modification scheme and remote switching control scheme, and then reconstructing a globally consistent verification object to characterize the operating status of the downhole vacuum pump system based on these two schemes. The globally consistent verification object includes the modified pipeline connectivity, the fluid transport paths between each vacuum pump unit, the configuration status of remote control components, and the switching control logic and action sequence information.

[0162] Subsequently, based on the global consistency verification object, a holistic consistency analysis was performed on the entire vacuum pump switching process. Specifically, taking the complete switching process of the vacuum pump from operating state to standby state or from standby state to operating state as the analysis object, the actions of each remote control component were simulated in different switching stages, and the corresponding pipeline connection relationships and fluid delivery path status were updated synchronously.

[0163] Based on this, consistency judgment is performed on the entire switching process, including: path connectivity consistency judgment, used to verify whether the delivery path corresponding to the target vacuum pump can form a continuous connection channel; path isolation consistency judgment, used to verify whether the delivery path corresponding to the original operating vacuum pump can be completely disconnected and there is no unexpected connection; control logic consistency judgment, used to verify whether the control sequence in the remote switching control scheme is consistent with the state change sequence in the actual switching process; and state determination consistency judgment, used to verify whether the feedback state of each remote control component is consistent with the preset target action state.

[0164] If any of the above consistency judgment results fails to meet the preset verification conditions, the global consistency verification is determined to have failed. Based on the type of failure, the corresponding pipeline modification location or control logic link is located, and the pipeline modification scheme or remote switching control scheme is readjusted and optimized. Subsequently, the above global consistency verification process is re-executed on the adjusted scheme until all consistency judgments meet the preset conditions. When the verification results meet the requirements for path connectivity, path isolation integrity, control logic consistency, and status feedback consistency, the global consistency verification is determined to have passed, and the final pipeline layout structure design scheme that can be used for remote automatic switching of downhole vacuum pumps is output.

[0165] For example, the first vacuum pump and the second vacuum pump share a manifold. In the optimized pipeline modification scheme, an electric control valve A3 is installed at the outlet of the first vacuum pump, an electric valve B3 is installed at the inlet of the second vacuum pump, and an isolation valve C3 is installed at the manifold node; in the remote switching control scheme, the switching sequence is set as follows: first close A3, then open C3, and finally open B3.

[0166] During the global consistency verification, the process of "switching from the first vacuum pump to the second vacuum pump" was simulated. During the execution, it was found that when B3 was turned on in advance, the manifold was still not completely isolated, resulting in a short-term connection between the first and second vacuum pumps. Therefore, the path isolation consistency was determined to fail.

[0167] To address this issue, the solution was adjusted by moving the closing action of C3 before the opening action of B3, and ensuring that A3 closes first, C3 closes and isolates, and B3 opens last. After adjustment and re-verification, the status of each pipeline showed: the first vacuum pump path was completely disconnected; the second vacuum pump path was normally conductive; the switching sequence was consistent with the control logic; therefore, the global consistency verification was deemed successful, and the final pipeline layout structure design scheme that can be used for remote automatic switching was output.
