Description

Technical Field

[0001] The present invention relates to the technical field of mine digital design, and particularly relates to a method for automatically arranging pipe assemblies based on RFID technology. Background Art

[0002] In conventional oil and gas field development, the pipe string system of a fracturing well site is widely used in fracturing operations for vertical wells, directional wells, etc. By precisely controlling the injection of fracturing fluid and proppant, effective formation transformation is achieved, and oil and gas recovery is increased. In conventional oil and gas field development, the pipe string system of a fracturing well site is widely used in fracturing operations for vertical wells, directional wells, etc. By precisely controlling the injection of fracturing fluid and proppant, effective formation transformation is achieved, and oil and gas recovery is increased. In the exploration and development of unconventional oil and gas resources such as shale gas and tight oil, fracturing technology is particularly important. The pipe string system of a fracturing well site can meet the requirements of large-scale, high-pressure, and large-displacement fracturing operations, helping to achieve the economic and effective development of unconventional oil and gas resources. With the wide application of horizontal well technology, the pipe string system of a fracturing well site plays a key role in horizontal well fracturing operations. By optimizing the pipe string layout and flow distribution, uniform fracture propagation within the horizontal well section is achieved, and the productivity and stability of oil and gas wells are improved. In some well factory models with high-efficiency development, the pipe string system of a fracturing well site needs to support continuous and efficient fracturing operations. Through an automated and intelligent control system, simultaneous operation of multiple fracturing pump trucks and rapid switching of the pipe string system are achieved, improving construction efficiency and safety.

[0003] The pipe string system of a fracturing well site generally consists of pipes and valves, and is used to distribute and control the flow of liquids and gases such as oil and natural gas. In the scenario of oil fracturing, the pipe string is used to pressurize and transport the liquid mixture underground for oil extraction. In a fracturing well site, it is necessary to monitor the status of the pipe string. Once a pipe string breakage occurs, it is very dangerous because the pressure in the pipe string is relatively high, and the ejected liquid can penetrate bricks.

[0004] The pipe string system of a fracturing well site is one of the indispensable important equipment in oil and gas field development. The traditional management mode of high-pressure fracturing pipe strings mainly shows the traditional paper-based manual recording method. With the continuous progress of technology and the increasing demand for oil and gas resource exploration and development, this method is prone to human errors, unable to trace the pipe strings, and the phenomenon of pipe strings being in service beyond their expiration date cannot be avoided, bringing serious safety hazards such as undetected pipe valves.

[0005] To prevent the failure of high-pressure pipe manifold management, it is necessary to digitally innovate the management mode. In recent years, some fracturing engineering service companies have introduced RFID systems to manage high-pressure pipe manifolds, achieving good practical results. It has improved the refinement and digitization of pipe manifolds, but this method does not have the visuality of graphics and cannot update data in real time. There are also cases where the drawings of pipe manifolds are manually drawn by engineers at the well site and then entered through software systems. However, the number of pipe manifolds at the well site reaches thousands, and this process is very cumbersome and cannot update the components and pipe manifolds at the well site in real time. Summary of the Invention

[0006] The present invention provides a method for automatically arranging pipe manifold configurations based on RFID technology to overcome the technical problems that the existing pipe manifold management system cannot automatically draw pipe manifold configurations, cannot intuitively judge the state of pipe manifolds, cannot update data in real time, and results in low efficiency of pipe manifold management.

[0060] In this solution, both ends of a line are defined as end points (i.e., main equipment), and the pipes and valves connecting the two end points are collectively called nodes. Nodes and end points are collectively called components;

[0061] S12. Use the RETE algorithm to learn the wellsite drawing based on the wellsite drawing requirements to obtain the pipe rack drawing rules, including:

[0062] End point drawing rules. The end point types include wellheads, fracturing skids, pipe rack skids, flow splitting skids, storage tanks, and pumps. The general rule is that wellheads, fracturing skids, pipe rack skids, flow splitting skids, storage tanks, and pumps can be connected through straight pipes, elbows, or multi-way connectors.

When the fracturing skid is connected to the pipe rack skid through an elbow, it is determined based on the model of the elbow and the specific angle value of the model;

[0071] The upper limit of the lines connected to the fracturing skid is 6, and there are components connected on all four sides; the upper limit of the connection quantity is determined according to the quantity of the input and output pipelines connected to the corresponding components in the well site.

[0073] The manifold skid or diverter skid is directly connected to straight pipes, flanged pipes, diverter valves, throttle valves and multi-way connectors to realize the distribution and control of fluids.

[0074] When the manifold skid is connected to the diverter skid through a straight pipe, the connection angle between the manifold skid and the diverter skid is 0 degree; when the manifold skid is connected to the diverter skid through a tee connector, the connection angle between the manifold skid and the diverter skid is determined according to the model of the tee connector and the corresponding angle value of the model.

[0075] When the manifold skid is connected to multiple diverter skids through a four-way connector, the connection angle between the manifold skid and the multiple diverter skids is determined according to the model of the four-way connector and the corresponding angle value of the model.

[0076] When the manifold skid is connected to multiple storage tanks through a six-way connector, the connection angle between the manifold skid and the multiple storage tanks is determined according to the model of the six-way connector and the corresponding angle value of the model.

[0077] When the diverter skid is connected to the storage tank through a straight pipe, the connection angle between the diverter skid and the storage tank is 0 degree; when the diverter skid is connected to the storage tank through an elbow, the connection angle between the diverter skid and the storage tank is determined based on the model of the elbow and the specific angle value of the model.

[0078] The upper limit of the lines connected to the manifold skid is 12; the upper limit of the lines connected to the diverter skid is 12, and there are components connected on all four sides of the manifold skid and the diverter skid; the upper limit of the connection quantity is determined according to the quantity of the input and output pipelines connected to the corresponding components in the well site.

[0079] The drawing rule for the fourth endpoint, that is, when the endpoint is a storage tank or a pump, draw according to the following rules:

[0080] The storage tank or pump is directly connected to straight pipes, flanged pipes, throttle valves, cocks and elbows to realize fluid storage and transportation.

[0081] When the storage tank is connected to the pump through a straight pipe, the connection angle between the storage tank and the pump is 0 degree; when the storage tank is connected to the pump through an elbow, the connection angle between the storage tank and the pump is determined based on the model of the elbow and the specific angle value of the model.

[0083] The specific processing steps of the RETE algorithm are as follows:

[0084] Create a root node. The root node is the entry of the inference network;

[0085] Add Requirement 1, that is, the requirement of which components the endpoints can be directly connected to. Take Pattern 1 (a pattern is the smallest atomic condition) from Requirement 1. The Alpha nodes start from 1 and the Beta nodes start from 2:

[0086] a) Check the parameter types in Pattern 1. If it is a new type, add a type node;

[0087] b) Check whether the corresponding Alpha node of Pattern 1 exists. If it exists, record the position of the node; if not, add Pattern 1 as an Alpha node to the network, and at the same time establish the first Alpha memory table according to the newly added Alpha node;

[0088] c) Repeat the step of judging whether the Alpha node corresponding to the pattern in Requirement 1 exists until all patterns are processed;

[0089] d) Combine the Beta nodes:

[0090] The left input node of Beta(2) is Alpha(1), and the right input node is Alpha(2); the left input node of Beta(i) is Beta(i - 1), and the right input node is Alpha(i), and inline the memory tables of the two parent nodes into its own memory table;

[0091] e) Repeat the step of combining the Beta nodes until all Beta nodes are processed;

[0092] f) Package the Then part of the action as the last node as Beta(n); where n is the number of Beta nodes;

[0093] Repeat steps a) to f) above until all requirements are processed to construct a rule network, and the rule network contains all the learned endpoint drawing rules.

[0094] In this solution, using the RETE algorithm combined with the actual wellsite drawings and wellsite drawing requirements can efficiently match complex rule patterns. For a large number of components (such as pipelines, valves, equipment) and drawing requirements (such as required connection methods, angles, layouts) in the wellsite drawings, the RETE algorithm can determine the rules corresponding to specific requirements through learning. The RETE algorithm can automatically generate a manifold design that meets the specifications, avoiding human negligence or errors, and ensuring that all designs comply with the same connection method, angle, and layout rules.

[0095] In a specific embodiment, the solution for setting RFID electronic tags for components in an actual well site and setting sensors for pipelines in the components is as follows:

[0096] Before installing components in the actual well site, assign a unique RFID electronic tag to each component in the well site, write the basic information of the device (such as device ID, model, installation date) into the RFID tag, and then submit it to the system for storage and bind it to the manifold data in the business system. When a component needs to be sent to the well, create the well information for the delivery, and associate the component to be delivered with the operation site;

[0097] At the same time, also set sensors for the pipelines in the components. Each time the pipeline is opened or closed, the time is recorded by the sensor. Then, based on the opening and closing times, confirm the running duration of the pipeline and store it in the business system for subsequent calls.

[0098] Setting RFID electronic tags for components and sensors for pipelines in the components can achieve real-time monitoring of the device status, facilitate the display of the pipeline status during subsequent drawing, and perform timely maintenance, providing data support for the drawing of subsequent configuration diagrams.

[0099] In a specific embodiment, the solution for obtaining data of components and pipelines in an actual well site based on RFID electronic tags and sensors is as follows:

[0100] Set the starting point and ending point of the well site. Use a scanning device to traverse and scan all components and pipelines from the starting point to the ending point of the well site according to the depth-first traversal algorithm. Based on the scanning times of the components and pipelines, form a preliminary connection relationship of the components and pipelines, and obtain the data of the components and pipelines. The data includes the names and scanning times of the components and pipelines. Obtain the running duration of the pipeline according to the sensor data; the scanning device is an AGV cart or a humanoid robot; calculate the (x, y) coordinates of each component based on the angles and lengths of the connected components, and upload the scanned data as JSON data to the system;

[0101] The depth - first traversal algorithm starts from an unvisited vertex, i.e., the set starting point of the well site. It explores branches as deep as possible along the edges until vertex v and all vertices reachable from v are visited, and the vertices are marked as visited. Then it backtracks to the starting vertex of the edge where v was discovered and explores another unvisited branch. This process is repeated until all vertices are visited. According to the piping layout rules of the fracturing well site, the fracturing well site is modeled as a graph. The endpoints such as fracturing skids, piping skids, diverter skids, and wellheads are set as vertices, and the connections between the vertices using straight pipes, flanged pipes, elbows, cocks, etc. are set as lines. The depth - first traversal algorithm is used to traverse the nodes in the graph through recursion or a stack until the target node is found or all nodes are traversed, that is, all components and pipes in the well site are scanned. At this time, the scanning result can be used as the preliminary connection relationship of the components and pipes. After traversal, re - check whether there are any components that have been missed, and re - scan the missed components and the surrounding components to ensure the accuracy of the connection relationship.

[0102] In this solution, by using an AGV cart or a humanoid robot to scan the RFID tags of all components and pipe manifolds in the well site based on the depth - first traversal algorithm, it can effectively handle the complex pipe network in the well site, improve efficiency, provide accurate data for drawing the drawings, and at the same time form a rough sequence from the starting point to the end point, providing a reference for determining the connection relationship when drawing the drawings.

[0103] In a specific embodiment, based on the piping layout rules, the data of the components in the actual well site are drawn to obtain a piping system configuration diagram. According to the piping system configuration diagram and the data of the components, the real - time state of the pipe manifold is obtained, including:

[0104] Use the piping layout rules and the preliminary connection relationship of the components and pipes to connect the actual well site components and pipes to obtain a component connection diagram. According to the angles and lengths of the corresponding endpoints of the connected components in the component connection diagram, the coordinates of each component are obtained; that is, the preliminary connection relationship of the components and pipes is complemented and modified through the piping layout rules to ensure the accuracy of the component connection relationship.

[0105] Design the components using SVG vector graphics. According to the coordinates of each component and the component connection diagram, draw the final piping system configuration diagram, and use different colors to visually display the pipe manifold data to obtain the real - time state of the pipe manifold.

[0106] Use the piping layout rules and the preliminary connection relationship of the components and pipes to connect the actual well site components and pipes to obtain a component connection diagram. At this time, the components in the component connection diagram are only the endpoints representing the components. Then, through the angles and lengths of the corresponding endpoints of the connected components, the coordinates of each component are obtained; design the legends of specific components through SVG, and use the legends to replace the endpoints on the corresponding component coordinates to form a final piping system configuration diagram drawing that can display different component types as shown inFigure 2 As shown, different colors in the figure represent the operation duration of the pipe manifold. For example, green represents that the pipe manifold has been operating for less than 220 hours, and red represents that the operation duration of the pipe manifold is longer and requires key monitoring. The figure includes endpoints such as the fracturing skid, pipe manifold skid, flow splitting skid, and wellhead, and nodes such as straight pipes, flange pipes, elbows, cocks, flow splitting valves, fracturing valves, throttle valves, three-way to six-way joints, etc. The nodes and endpoints drawn on the figure are collectively referred to as components.

[0107] In this solution, an SVG vector diagram is designed to represent each device and pipe manifold of the high-pressure pipe manifold system in the fracturing well site. The components in the configuration diagram are associated with the actual devices, the operation data of the devices is collected, and the color of the vector diagram is set. Red represents that the device or pipe manifold has been operating for too long and requires key maintenance; green represents that the device is healthy; blue represents that it has been operating for a period of time and requires periodic maintenance. It has the visuality of graphics, can update the data in real time, is convenient to view, and is convenient for timely maintenance of the components or pipe manifolds in the well site, reducing the time for calling pipeline data and facilitating the management personnel to directly confirm the status of all pipe manifolds for maintenance or adjustment. At the same time, when drawing, the RETE algorithm can automatically check whether the connection method, angle, device layout, etc. conform to the rules. For example, condition nodes are set in the network to check whether the connection angle meets the regulations to ensure that the drawn drawing is accurate.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
