For example, during the fracturing operation, information about the fracturing operation site can be obtained to determine operating instructions for the equipment, allowing for further intelligent control of the equipment.

[0027] The control method for the fracturing operation provided in the embodiment of the present application can be executed by a control device, wherein the control device can be one electronic device or multiple electronic devices. That is to say, the control method for the fracturing operation provided in the embodiment of the present application can be executed by one electronic device, wherein the electronic device can be, for example, an intelligent fracturing decision-making and command device, or a terminal device such as a desktop computer, a laptop computer, a mobile phone, a tablet computer, or a server, such as an independent physical server, a server cluster composed of multiple servers, and a cloud server capable of cloud computing. In the case where the control method for the fracturing operation provided in the embodiment of the present application is executed by multiple electronic devices, these multiple electronic devices can form a service cluster, which cooperate with each other to complete each step.

[0028] The control method for the fracturing operation provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0029] Please refer to Figure 1, which is a flow chart of a method for controlling a fracturing operation provided in an embodiment of the present application. As shown in Figure 1, the method includes the following steps:

[0030] Step 110: Controlling the device to obtain operation information of the operating equipment at the fracturing operation site;

[0031] In an embodiment of the present application, the control device may be an instrument device at a fracturing operation site, and the control device may include a data acquisition module, which may be used to obtain operation information of the operation equipment at the fracturing operation site. The operation equipment may be various equipment at the fracturing operation site, and may include a fracturing pump group, a wellhead manifold, a sand mixing device, a mixing device, a sand transport device, a water supply tank group, a sand supply tank group, and a low-pressure manifold. The operation information may include rheological parameters of the fracturing fluid, construction pressure, displacement, wellbore parameters (such as measurement depth, inner diameter, well inclination, azimuth, temperature), sand addition type, sand flow rate, sand mixing status, cumulative sand volume, remaining sand volume, liquid volume, and wellhead manifold valve opening. The operation equipment may report the operation information of the operation equipment in real time during the fracturing operation. Based on this, the control device can obtain real-time operation information of the operation equipment at the fracturing operation site.

[0032] In an embodiment of the present application, the control device may include an equipment construction parameter management module, which can be used to intuitively display the construction parameters of the operating equipment at the fracturing operation site and the working status of the operating equipment in real time.

[0033] Step 120: The control device obtains the construction effect of the operation equipment based on the operation information;

[0034] In an embodiment of the present application, the operating equipment at the fracturing operation site can report its operating information in real time. After the control device receives the operating information, it can obtain the operating results of the operating equipment from the operating information. The operating results of the operating equipment can be determined based on information such as the rheological parameters of the fracturing fluid, the operating pressure, the displacement, the wellbore parameters, the sand addition type, and the sand flow rate contained in the operating information. The operating results may include the operating pressure at the fracturing operation site.

[0035] In the embodiment of the present application, the control device obtains the construction effect, which can be used to monitor the fracturing construction effect at the operation construction site, and monitor whether the operation construction site needs to be adjusted to ensure that the fracturing operation task can be successfully completed.

[0036] Step 130: The control device acquires target information of the operating device, where the target information includes at least one of safety information related to the fracturing operation site of the operating device, health diagnosis information of the operating device, and abnormal alarm information of the operating device.

[0037] In an embodiment of the present application, the safety information related to the fracturing operation site of the operating equipment may include information on identifying manifold leaks, identifying information on personnel intrusion in high-pressure areas, and high-temperature or fire warnings. Specifically, by installing sensors (e.g., temperature sensors) and cameras at the fracturing operation site, high-temperature or fire warnings at the fracturing operation site can be detected by the temperature sensors, and the presence of personnel intrusion in high-pressure areas (areas with higher operating pressures) at the fracturing operation site can be determined by the cameras.

[0038] In the embodiments of the present application, by collecting safety information related to the fracturing operation site of the operating equipment, it is possible to determine whether unsafe behavior occurs at the fracturing operation site, and whether the operating equipment at the fracturing operation site is in an unsafe state. By acquiring safety information related to the fracturing operation site of the operating equipment, the control device can ensure the safety of the fracturing operation site and avoid potential safety hazards.

[0039] In an embodiment of the present application, the health diagnostic information of the operating equipment may be status monitoring information and fault monitoring information of key operating equipment at the fracturing operation site. Specifically, the health diagnostic information of the operating equipment may include at least one of the following: plunger pump health diagnostic information, motor health diagnostic information, centrifugal pump health diagnostic information, and sand auger health diagnostic information. The status of key operating equipment such as the plunger pump, motor, centrifugal pump, or sand auger can be monitored by installing sensors (such as vibration sensors and pressure sensors) at the fracturing operation site.

[0040] In an embodiment of the present application, the abnormal alarm information of the operating equipment may be the status alarm information of the operating equipment during the fracturing operation. Specifically, it may include that when the pressure of the operating equipment exceeds a preset pressure threshold, or the temperature of the operating equipment exceeds a preset temperature threshold, the operating equipment will send pressure warning information or high temperature warning information to the control device.

[0041] Step 140: The control device determines an operation instruction for the operation device based on the construction effect and the target information;

[0042] In an embodiment of the present application, the control device may include a construction decision module, which can be used to make autonomous decisions on fracturing operations and determine operating instructions for the operating equipment based on relevant information obtained at the fracturing operation site (such as the construction effect of the operating equipment and target information).

[0043] In an embodiment of the present application, after the control device obtains the construction effect of the operating equipment and at least one of the target information (safety information related to the fracturing operation site of the operating equipment, health diagnosis information of the operating equipment, and abnormal alarm information of the operating equipment), a comprehensive decision can be made based on the at least two types of information to determine the operating instructions of the operating equipment. The operating instructions may include sand volume maintenance instructions, displacement maintenance instructions, sand reduction ratio instructions, sand stop instructions, displacement reduction instructions, and shutdown instructions. At the same time, the operating instructions of the operating equipment may include operating equipment parameters related to the operating instructions. For example, if the operating instruction is a sand reduction instruction, the operating instruction may include specific parameters for the sand reduction amount this time.

[0044] In an embodiment of the present application, the operation instructions of the operation equipment can be determined based on any one of the construction effect and the target information (safety information related to the fracturing operation site of the operation equipment, health diagnosis information of the operation equipment, and abnormal alarm information of the operation equipment); the operation instructions of the operation equipment can also be determined based on any two of the construction effect and the target information; the operation instructions of the operation equipment can also be determined based on the construction effect, safety information related to the fracturing operation site of the operation equipment, health diagnosis information of the operation equipment, and abnormal alarm information of the operation equipment.

[0045] In one embodiment of the present application, the operation instruction includes an operation process switching instruction, and the operation process switching instruction is used to instruct the operation equipment to switch the operation process. The control device obtains the operation information of the operation equipment at the operation site, including: the control device receives real-time operation data transmitted by the operation equipment at the operation site. The control device determines the operation instruction of the operation equipment based on the operation information and the target information, including: the control device determines whether the operation equipment meets the operation switching condition based on the real-time operation data and the target information; if the operation equipment meets the operation switching condition, the control device generates a operation process switching instruction.

[0046] In an embodiment of the present application, the control device may include a full-process control and process visualization module, which is used to control the process of the on-site fracturing operation and visualize the real-time operating data of the on-site equipment (including high-pressure equipment and low-pressure equipment). Specifically, before the fracturing operation begins, the management personnel can use the full-process and process visualization module to select the start of the fracturing operation process. At the same time, a specific fracturing operation process can also be selected to control the on-site equipment. The fracturing operation process may include a pressure test process, a cycle emptying process, and other processes.

[0047] In the full-process control and process visualization module, a stage data table of the fracturing construction process can be pre-set. The stage data table describes the parameters of the operating equipment at the fracturing operation site in each process. The content of the stage data table can be determined based on the experience of historical fracturing operations.

[0048] In an embodiment of the present application, the control device acquires real-time operating data of operating equipment at the fracturing operation site. When the control device determines that the current operating data of the operating equipment meets an operation switching condition, the control device may generate an operation process switching instruction. The operation process switching instruction may include relevant parameters of the operating equipment in the next operation process. The operation switching condition may be determined based on the stage data table.

[0049] In an embodiment of the present application, the operation data of the fracturing operation site can be obtained in real time by controlling the equipment. When the operation data meets the operation switching conditions, the operation process switching instruction is determined to control the operation equipment at the fracturing operation site to perform the next process of the fracturing operation. During the entire process, there is no need for manual inspection to check whether to enter the next process of the fracturing operation, and the entire process of the fracturing operation can be completed autonomously.

[0050] In one embodiment of the present application, referring to FIG. 2 , the control device may include a full-process control and process visualization module, an equipment construction parameter management module, a construction decision module, and a data acquisition module.

[0051] Step 150: The control device sends the operation instruction to the operation device, where the operation instruction is used to control the operation task of the operation device.

[0052] In the embodiment of the present application, after the control device determines the operation instruction, the equipment at the fracturing operation site can be controlled by the operation instruction (for example, reducing the sand ratio, reducing the displacement, and shutting down, etc.).

[0053] In one embodiment of the present application, in step 150, the control device sends the operation instruction to the operation device, including: the control device sends the operation instruction to the control center, so that the control center obtains the target operation instruction based on the operation instruction, and the target operation instruction is used to directly control the operation of the operation device.

[0054] In an embodiment of the present application, the operating equipment at the fracturing operation site can be further controlled by the control center. Specifically, after the control device determines the operating instruction of the operating equipment, the operating instruction can be sent to the control center, and the control center further determines the target operating instruction that directly controls the operation of the operating equipment at the fracturing operation site based on the operating instruction. For example, the operating instruction is a sand reduction instruction, and the operating instruction includes specific parameters of the sand reduction amount. The control center can obtain the sand reduction instruction and the specific parameters of the sand reduction amount, and based on this, it can assign the sand reduction instruction to a specific operating equipment to execute the sand reduction instruction, that is, determine the target operating instruction, and the target operating instruction directly controls the operation of the specific operating equipment.

[0055] In the embodiment of the present application, the operating equipment at the fracturing operation site can be directly controlled by the control center, the work of the operating equipment can be determined more carefully, and the operating instructions issued by the control equipment can be successfully completed.

[0056] In an embodiment of the present application, a control device obtains operating information of an operating device at a work site; based on the operating information, the control device obtains a construction effect of the operating device; the control device obtains target information of the operating device, the target information including at least one of safety information related to the operating site of the operating device, health diagnostic information of the operating device, and abnormality alarm information of the operating device; the control device determines an operating instruction for the operating device based on the operating effect and the target information; and the control device sends the operating instruction to the operating device, the operating instruction being used to control the operating task of the operating device. In this manner, the control device can determine an operating instruction for the operating device at the fracturing operation site based on the construction effect of the operating device at the fracturing operation site and at least one of safety information related to the fracturing operation site of the operating device, health diagnostic information of the operating device, and abnormality alarm information of the operating device, and control the operating task of the operating device using the operating instruction. The operating instruction can be determined based on at least two types of information at the operation site, thereby improving the accuracy of the operating instruction. Furthermore, the entire process can be executed by the control device without manual intervention, thereby resolving the high labor cost issue of related technologies.

[0057] Please refer to FIG3 , which is a flow chart of a method for controlling a fracturing operation provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0058] Step 310: The control device obtains operation information of the operation equipment at the operation site;

[0059] Step 320: The control device obtains the construction effect of the operation equipment based on the operation information;

[0060] Step 330: The control device obtains target information of the operating device, where the target information includes at least one of safety information related to the operating site of the operating device, health diagnosis information of the operating device, and abnormal alarm information of the operating device.

[0061] Step 340: The control device determines an operation instruction for the operation device based on the construction effect and the target information;

[0062] Step 350: The control device sends the operation instruction to the control center;

[0063] In an embodiment of the present application, the control center can be used to further directly manage the operating equipment at the fracturing operation site. The control equipment sends the operation instruction to the control center, and the control center can further issue the operation instruction to the operating equipment corresponding to the operation instruction based on the operation instruction.

[0064] For example, in one embodiment of the present application, the operating equipment includes M first operating equipment, and the control center includes M first control modules corresponding one-to-one to the M first operating equipment, each control module is used to control the first operating equipment corresponding to the module, and M is a positive integer.

[0065] In this embodiment of the present application, the first operating equipment may include a sand mixing device, a compounding device, a sand conveying device, a water supply tank group, a sand supply tank group, and a low-pressure manifold. Each type of first operating equipment may correspond to a first control module. Specifically, the sand mixing device may correspond to a sand mixing linkage control module, the compounding device may correspond to a compounding linkage control module, the sand conveying device may correspond to a sand conveying linkage control module, the water supply tank group may correspond to a liquid tank linkage control module, the sand supply tank group may correspond to a sand tank linkage control module, and the low-pressure manifold may correspond to a low-pressure manifold remote control module.

[0066] In this embodiment of the present application, the control center includes M first control modules corresponding one-to-one to the M first operating devices, each of which is configured to control the first operating device corresponding to the module. This enables cluster control of the M first operating devices, and by enabling each first control module to control a type of first operating device, the M first operating devices can be effectively managed and controlled.

[0067] For example, in one embodiment of the present application, the operating equipment includes P first operating equipment located in a first equipment area and Q second operating equipment located in a second equipment area; P and Q are both positive integers, and the pressure at which the first operating equipment performs fracturing operations is less than the pressure at which the second operating equipment performs fracturing operations; the operating instructions include first operating instructions and / or second operating instructions; the control center includes a first control center and a second control center.

[0068] In the embodiments of the present application, the operating equipment can be divided into high-pressure equipment and low-pressure equipment according to the pressure at which the operating equipment is operated at the fracturing operation site. For example, during the actual operation process, the pressure of the fracturing truck, remote-controlled hydraulic station and wellhead manifold can generally reach 50 MPa, or even nearly 100 MPa, which is a relatively high pressure; while during the actual operation process, the construction pressure of equipment such as sand mixing equipment, mixing equipment, sand transport equipment, water supply tank group, sand supply tank group and low-pressure manifold is relatively low.

[0069] In an embodiment of the present application, the first equipment area may be a low-pressure equipment area, and the first operating equipment may be low-pressure equipment (including sand mixing equipment, compounding equipment, sand transport equipment, water supply tank group, sand supply tank group, and low-pressure manifold). The second equipment area may be a high-pressure equipment area, and the second operating equipment may be high-pressure equipment (including fracturing trucks, remote hydraulic stations, and wellhead manifolds). The first control center may be a low-pressure system control center, and the second control center may be a high-pressure system control center. The first control center and the second control center may be used to control the equipment in the first equipment area and the second equipment area, respectively.

[0070] In an embodiment of the present application, during a fracturing operation, the operation instructions determined by the control device can be used to control the low-pressure equipment and / or the high-pressure equipment. Specifically, as shown in FIG4 , the control device can send the operation instructions to a data command forwarding server, which converts the operation instructions into a first operation instruction for controlling the low-pressure equipment and / or a second operation instruction for controlling the high-pressure equipment. The first operation instruction is transmitted to a first control center, and the second operation instruction is transmitted to a second control center.

[0071] Step 360: The control center obtains a target operation instruction based on the operation instruction; wherein the target operation instruction is used to directly control the operation of the operation equipment, and the control center is located on the transmission path between the control equipment and the operation equipment.

[0072] In an embodiment of the present application, the operating equipment at the fracturing operation site can be further controlled by the control center. Specifically, after the control device determines the operating instruction of the operating equipment, the operating instruction can be sent to the control center, and the control center further determines the target operating instruction that directly controls the operation of the operating equipment at the fracturing operation site based on the operating instruction. For example, the operating instruction is a sand reduction instruction, and the operating instruction includes specific parameters of the sand reduction amount. The control center can obtain the sand reduction instruction and the specific parameters of the sand reduction amount, and based on this, it can assign the sand reduction instruction to a specific operating equipment to execute the sand reduction instruction, that is, determine the target operating instruction, and the target operating instruction directly controls the operation of the specific operating equipment.

[0073] In one embodiment of the present application, the operation instruction includes a first operation instruction and / or a second operation instruction; and the control center includes a first control center and a second control center. In step 360, the control center obtains a target operation instruction based on the operation instruction, including: the first control center obtains a first target operation instruction based on the first operation instruction, the first target operation instruction being used to directly control the operation of at least one of the P first operation devices; wherein the first control center is in communication with the P first operation devices; or, the second control center obtains a second target operation instruction based on the second operation instruction, the second target operation instruction being used to directly control the operation of at least one of the Q second operation devices; wherein the second control center is in communication with the Q second operation devices.

[0074] In an embodiment of the present application, as shown in FIG5 , the first control center may be a low-pressure system control center, which may include a sand mixing linkage control module, a compounding linkage control module, a sand transport linkage control module, a sand tank linkage control module, a liquid tank linkage control module, and a low-pressure manifold remote control module. A dedicated intelligent control module may be provided within the low-pressure system control center. Based on a first operating instruction sent by the control device, the dedicated intelligent control module may convert the first operating instruction into a first target operating control instruction for controlling the first operating device corresponding to the first control module. There may be multiple first target operating control instructions, and the operation of at least one of the P first operating devices may be directly controlled by the first target operating control instruction.

[0075] In an embodiment of the present application, as shown in FIG6 , the second control center may be a high-pressure system control center. The second operating equipment includes a fracturing truck, a wellhead valve, and a remote-controlled hydraulic station. The high-pressure system control center may include a fracturing pump group control module, an automatic displacement control module, an automatic circulation / emptying control module, and a wellhead manifold remote control module. The wellhead manifold remote control module may be configured to obtain a second target operation control instruction based on the second operation instruction. The second target operation control instruction may be a wellhead manifold valve control instruction. Using the wellhead manifold valve control instruction, the wellhead manifold remote control module may control the opening and closing of the wellhead or manifold valves in the high-pressure equipment area.

[0076] In one embodiment of the present application, the second control center includes a first control module and a second control module; the second operating equipment includes a fracturing truck; the second control center obtains a second target operating instruction based on the second operating instruction, including: the first control module generates a fracturing pump control instruction based on the equipment parameters in the second operating instruction, and transmits the fracturing pump control instruction to the second control module; the second control module controls the fracturing operation of the fracturing truck based on the fracturing pump control instruction.

[0077] In an embodiment of the present application, the first control module may include an automatic displacement control module and an automatic circulation / emptying control module, and the second control module may include a fracturing pump group control module. Specifically, the automatic displacement control module may include a dedicated intelligent automatic displacement allocation algorithm module. When the second control center receives the second operation instruction, the automatic displacement control module may receive the displacement control instruction and displacement and pressure protection data. The automatic displacement control module may convert the displacement control instruction and displacement and pressure protection data into a fracturing pump control instruction through the dedicated intelligent automatic displacement allocation algorithm module, and transmit the fracturing pump control instruction to the fracturing pump group control module.

[0078] In an embodiment of the present application, after the fracturing pump control module receives the fracturing pump control instruction transmitted by the automatic displacement control module, the fracturing pump control module can directly control the fracturing truck (including electric-driven fracturing truck, diesel-driven fracturing truck and turbine fracturing pump truck) in the high-pressure equipment area to perform intelligent automatic displacement distribution cruising.

[0079] In addition, when the second control center receives the second operation instruction, the automatic circulation / emptying control module may receive the automatic circulation / emptying process control command and data such as displacement, duration, etc. The automatic circulation / emptying control module may determine an automatic circulation or emptying control instruction for the fracturing pump, i.e., a fracturing pump control instruction, based on the automatic circulation / emptying process control command and data such as displacement, duration, etc., and transmit the fracturing pump control instruction to the fracturing pump control module.

[0080] In an embodiment of the present application, after the fracturing pump control module receives the fracturing pump control instruction transmitted by the automatic circulation / emptying control module, the fracturing pump control module can directly control the fracturing truck (including electric-driven fracturing truck, diesel-driven fracturing truck and turbine fracturing pump truck) in the high-pressure equipment area to perform automatic circulation or emptying control process.

[0081] In an embodiment of the present application, the control device transmits the operation instruction to a control center; the control center obtains a target operation instruction based on the operation instruction; wherein the target operation instruction is used to directly control the operation of the operation equipment, and the control center is located on the transmission path between the control device and the operation equipment. In this way, the control center can directly control the operation equipment at the fracturing operation site, more precisely determine the operation of each operation equipment at the fracturing operation site, and smoothly complete the operation instruction issued by the control device.

[0082] Please refer to Figures 7 and 8. Figure 7 is a complete flow chart of a control method for a fracturing operation provided in an embodiment of the present application, and Figure 8 is an overall conceptual diagram of a control method for a fracturing operation provided in an embodiment of the present application.

[0083] As shown in Figure 8, the control equipment may be an intelligent decision-making and command equipment, which may include a full-process control and process visualization module, an equipment construction parameter management module, a construction decision module, and a data acquisition module. The first control center may be the low-pressure system control center, and the first equipment area may be the low-pressure equipment area.
