Abstract
Description
Technical Field
[0001] This disclosure pertains to the field of oil and gas field development technology, and particularly relates to a wireline operation auxiliary method, apparatus, electronic equipment, and storage medium. Background Technology
[0002] With the accelerated green and low-carbon transformation of my country's energy sector, natural gas consumption continues to rise, and the dependence on imported natural gas has exceeded the safety warning line, seriously threatening my country's energy security. Wireline work is a technical means to increase and stabilize natural gas production. Wireline work involves connecting a tool string with a steel wire wound around a winch, which is then lowered into the wellbore of the oil and gas well. Operations such as sampling, drilling, cutting, and plunger insertion are achieved through raising, lowering, and impacting the tool string.
[0003] Currently, when performing wireline operations, operators will check the real-time wireline operation data displayed on the wireline operation operating system control panel. The wireline operation data includes wireline depth, wireline suspension weight, and wireline speed. Based on the real-time wireline operation data and the well structure diagram, the operator will manually estimate the current position of the tool string inside the wellbore and perform corresponding wireline operations based on the estimated position.
[0004] With the advancement of natural gas development technology, a large number of highly deviated wells and horizontal wells have emerged. The downhole conditions of these wells are relatively complex, and the gaps in the tool string within the wellbore are very small. The tool string is raised and lowered by manually estimating its position. Due to the small gaps in the wellbore, the tool string is prone to encountering obstruction or getting stuck. Furthermore, if the speed is too high when encountering the build-up point, it is more likely to damage the wellbore itself.
[0005] Therefore, accurately locating the real-time position of the tool string inside the wellbore to assist operators in smoothly carrying out wireline operations is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] To address the aforementioned issues, this disclosure provides a wireline operation assistance method, the purpose of which is to accurately locate the real-time position of the tool string inside the wellbore, thereby assisting operators in smoothly carrying out wireline operations.
[0007] To achieve the above objectives, this disclosure mainly provides the following technical solutions:
[0008] In a first aspect, this disclosure provides a method for assisting in wire mesh operations, including:
[0009] Construct a wireline operation scenario and operation process model for the target oil and gas well, wherein the operation process model is used to simulate the wireline operation process of the target oil and gas well;
[0010] Based on the wire rope operation scenario, a first screen is displayed, showing the positional relationship between the wellbore of the target oil and gas well and the target tool string, wherein the target tool string is the tool string inside the wellbore;
[0011] Obtain the current wireline operation data for the target oil and gas well;
[0012] The first screen is updated using the wireline operation data and the operation process model to obtain a second screen, which is used to display the real-time position of the target tool string inside the wellbore.
[0013] Secondly, this disclosure provides a wire rope operation auxiliary device, comprising:
[0014] A construction unit is used to construct a wireline operation scenario and operation process model for the target oil and gas well, wherein the operation process model is used to simulate the wireline operation process of the target oil and gas well;
[0015] The display unit is used to display a first screen based on the wire rope operation scenario. The first screen displays the positional relationship between the wellbore of the target oil and gas well and the target tool string, wherein the target tool string is the tool string inside the wellbore.
[0016] The acquisition unit is used to acquire the current wireline operation data of the target oil and gas well;
[0017] An update unit is used to update the first screen using the wire rope operation data and the operation process model to obtain a second screen, which is used to display the real-time position of the target tool string in the wellbore.
[0018] On the other hand, this disclosure also provides a storage medium for storing a computer program, wherein the computer program, when running, controls the device where the storage medium is located to execute the method described in the first aspect.
[0019] On the other hand, this disclosure also provides an electronic device, the device including at least one processor, and at least one memory and bus connected to the processor; wherein the processor and the memory communicate with each other through the bus; the processor is used to call program instructions in the memory to execute the method as described in the first aspect above.
[0020] Compared with the prior art, this disclosure has the following advantages:
[0021] This disclosure constructs a wireline operation scenario for a target oil and gas well to simulate the actual operation of the target oil and gas well; it also constructs an operation process model for the target oil and gas well to simulate the actual wireline operation process. Based on the wireline operation scenario, a first screen is displayed, showing the positional relationship between the wellbore and the target tool string. Current wireline operation data for the target oil and gas well is acquired, and the first screen is updated using this data and the operation process model to obtain a second screen. By updating the first screen, the positional relationship between the wellbore and the target tool string in both the first and second screens changes accordingly with the real-time wireline operation data, thus displaying the dynamic effect of the target tool string moving within the wellbore. Since this dynamic effect is generated based on the current wireline operation data, and the wireline depth in the data corresponds to the wellbore, the position of the target tool string in the wellbore in the second screen matches its actual current position. Therefore, this disclosure displays the real-time position of the target tool string within the wellbore to the operator, achieving precise positioning of the target tool string and assisting the operator in successfully performing wireline operations.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0029] Currently, during wireline operations, operators can only obtain three data points—wire suspension weight, wire depth, and wire speed—through the wireline operation control panel. These data, combined with the wellbore structure diagram and their own operational experience, are then used to comprehensively analyze and estimate the current position of the tool string within the wellbore. Human estimation is prone to errors, inefficient, and cannot achieve precise positioning; it may even mislead operations and lead to downhole accidents.
[0030] Therefore, this disclosure provides a full-scene wire rope operation navigation system, which consists of four parts: a data acquisition system, a data simulation system, a data analysis system, and a display system.
[0031] The data acquisition system collects real-time data on wire rope operations, such as wire rope depth, wire rope speed, and wire rope weight. It mainly consists of a real-time data acquisition black box and a real-time data converter. Real-time data acquisition black box: Measurement range: 0-5V, 4-20mA; Number of channels: ≥4; Automatic input switching; Balance range: -120% ≤ Balance range ≤ 120%; Maximum sampling frequency: ≥1000SPS; Resolution: 0.001V, 0.001mA; Measurement accuracy: -0.05%FS ≤ Measurement accuracy ≤ 0.05%FS; Stability: ±0.001 / 4h; Calibration method: Power-on self-calibration; Calibration voltage: 2.0V, accuracy maintained at least ±0.01%; A / D resolution: 24bit; Acquisition method: Includes at least continuous acquisition and triggered acquisition; Synchronization accuracy: ≤1ms; Data storage capacity: ≥1GB Flash; Wireless radio frequency: 2.4G DSSS; Communication distance: 600-meter line-of-sight distance; Maximum air transmission rate: 250Kbps. Real-time data converter: Supports multiple TCP / IP specifications, including TCP, UDP, IP, I CMP, and ARP; Operating environment: -25℃ to 75℃.
[0032] A data simulation system can include models of operating equipment and models of operating processes. It is used to simulate wireline operations in oil and gas wells, as well as the wireline operation process itself. The operating equipment models include, for example: winch simulation models, wireline simulation models, tool string simulation models, pulley simulation models, wellhead tool simulation models, and downhole wellbore simulation models.
[0033] The data analysis system can use various models to predict the limits of wireline operation by inputting well inclination data, pressure and temperature gradient data, casing and tubing data, tool string data, universal joint length data, friction coefficient, well fluid data, and acquired wireline operation data. These limits include the maximum depth of the tool string, the maximum speed of the tool string, the minimum speed of the tool string, and the upward force of the tool during operation. This information can then guide operators in their on-site work.
[0034] The display system can include an explosion-proof touch screen, and data from the data analysis system and data acquisition system can be displayed through the display system. At the same time, the display system can also display 3D animations of the wire rope operation process.
[0035] Corresponding to the aforementioned all-scenario wire rope operation navigation system, this disclosure also provides a wire rope operation assistance method, such as... Figure 1 As shown, the wire cutting assistance method of this disclosure includes:
[0036] 101. Construct a wireline operation scenario and operation process model for the target oil and gas well.
[0037] The wireline operation scenario simulates the actual wireline operation of the target oil and gas well. The wireline operation scenario is constructed from at least a wellbore model, a wireline model, a winch model, and a tool string model. The operation process model is used to simulate the wireline operation process of the target oil and gas well.
[0038] In this step, all equipment involved in wireline operations on the target oil and gas well is identified. Modeling is then performed on each piece of equipment, resulting in multiple equipment models, such as the wellbore model, wireline model, winch model, and tool string model. The wellbore model allows the wellbore of the target oil and gas well to be displayed on a monitor showing the parameters. A wireline operation scenario is then constructed using all the built equipment models. Furthermore, the equipment used in the wireline operation, including the winch, wireline, and tool string, is analyzed, and an operation process model is constructed based on the movement relationships of these three components during the operation.
[0039] 102. Based on the wire rope operation scenario, display the first screen.
[0040] The first screen shows the positional relationship between the wellbore of the target oil and gas well and the target tool string, which is the tool string inside the wellbore.
[0041] In this step, based on the wireline operation scenario, the entire scene of the target oil and gas well wireline operation can be displayed on the display system's monitor. This includes displaying wellhead equipment, various tubing strings in the wellbore, as well as the winch, wireline, and tool string. The first screen clearly shows the positional relationship between the target tool string and the wellbore. The tool string in the first screen may not be lowered into the wellbore or may be located inside the wellbore, depending on the actual scenario.
[0042] It should be noted that if the wireline operation data from the previous moment is obtained before displaying the first screen, the positional relationship between the wellbore and the target tool string in the first screen is determined based on the wireline operation data from the previous moment. If the wireline operation data from the previous moment is not obtained, the positional relationship can be determined as the tool string not being lowered into the wellbore. It should also be noted that the first screen can also display the wireline and winch of the target oil and gas well, with the target tool string connected to that wireline.
[0043] 103. Obtain the current wireline operation data for the target oil and gas well.
[0044] The wireline operation data refers to real-time data collected during wireline operations on the target oil and gas well. This data may include wireline depth, wireline suspension weight, and wireline speed.
[0045] In this step, the data acquisition system can collect real-time data of wireline operations to obtain the current wireline operation data of the target oil and gas well, so as to use the wireline operation data to determine the current location of the target tool string connected to the wireline.
[0046] 104. Update the first screen using the wire rope operation data and operation process model to obtain the second screen.
[0047] The second screen displays the real-time position of the target tool string within the wellbore.
[0048] In this step, using wireline operation data and the operation process model, the positional changes of the wireline and tool string between the previous and current moments can be determined. Based on these positional changes, the first screen is updated to obtain a second screen corresponding to the current wireline operation data. In other words, compared to the second screen, the wellbore graphic remains unchanged, while the winch, wireline, and tool string continuously update their corresponding graphics as time and wireline operation data change, achieving a real-time animation effect of the tool string's position changing within the wellbore. Operators can intuitively understand the current position of the tool string within the wellbore by observing the animation on the monitor.
[0049] This disclosure constructs a wireline operation scenario for a target oil and gas well to simulate a real-world operation scenario; it also constructs an operation process model for the target oil and gas well to simulate the actual wireline operation process. Based on the wireline operation scenario, a first screen is displayed, showing the positional relationship between the wellbore and the target tool string. Current wireline operation data for the target oil and gas well is acquired, and the first screen is updated using this data and the operation process model to obtain a second screen. By updating the first screen, the positional relationship between the wellbore and the target tool string in both the first and second screens changes accordingly with the real-time wireline operation data, thus displaying the dynamic effect of the target tool string moving within the wellbore. Since this dynamic effect is generated based on the current wireline operation data, and the wireline depth in the data corresponds to the wellbore, the position of the target tool string in the wellbore in the second screen matches its current actual position. Therefore, this disclosure shows the operator the real-time position of the target tool string within the wellbore, achieving precise positioning of the target tool string and assisting the operator in successfully performing wireline operations.
[0050] To illustrate in more detail the wire rope operation assistance method proposed in this disclosure, another embodiment of the wire rope operation assistance method is provided. The specific implementation steps of this embodiment are as follows: Figure 2 As shown, it includes:
[0051] 201. Construct a wireline operation scenario and operation process model for the target oil and gas well. The wireline operation scenario is built from multiple operation equipment models.
[0052] The operating equipment models in this embodiment are a winch simulation model, a wire rope simulation model, a tool string simulation model, a pulley simulation model, a wellhead tool simulation model, and a downhole wellbore simulation model. The specific details of each simulation model are as follows:
[0053] The winch simulation model simulates the winch and turntable models and marks the real-time operating parameters of the winch and turntable.
[0054] The toolchain simulation model establishes multiple toolchain models, which are then combined by selection and dimensioning.
[0055] The steel wire simulation model is established based on the length, diameter, and position of the steel wire.
[0056] The pulley simulation model is modeled based on all the pulleys through which the rope passes, and the pulley model is fixed relative to the winch and the well tools.
[0057] The wellhead tool simulation model creates simulation models of wellhead tools, blowouters, oil and gas production trees, as well as model combination simulations.
[0058] The downhole wellbore simulation model automatically generates a three-dimensional model of the wellbore structure based on logging data.
[0059] All of the above simulation models can be adapted to the size of the monitor screen.
[0060] The operation process model can include a wire rope winch operation process simulation model and a tool string operation process simulation model. By determining the relative motion relationships between the tool string, wire, and wire rope winch, as well as the relative position changes of the tool string during the motion process, software scripts are used to animate the motion parameters of the tool string, the wire rope winch, and the wire rope operation parameters. The animation is adjusted based on real-time transmitted data to achieve real-time animation simulation of wire rope operations. The specific details of the wire rope winch operation process simulation model and the tool string operation process simulation model are as follows:
[0061] The simulation model of the wire rope winch operation process simulates the operation process of the winch, and combines the simulation actions with the actual operation to achieve visualization output.
[0062] The toolchain operation process simulation model simulates the toolchain's running speed, direction, curvature, etc. at different build-up points and under different well conditions during operation, realizing the synchronization and output of the toolchain's operation process for visualization.
[0063] This application embodiment utilizes a wireline operation scenario and operation process model to achieve full-scenario simulation of wireline operations at the target oil and gas well.
[0064] In one feasible approach, the steps for constructing a job process model are as follows:
[0065] Step 1: Obtain wire data, winch data, and tool string data. Wire data includes historical wire movement data.
[0066] The wire data includes wire attribute data and historical wire movement data. Wire attribute data describes properties such as wire length and diameter. Historical wire movement data can be collected historical wire operation data. Winch data describes the attributes of the winch and turntable. Toolchain data describes the volume, weight, and other attributes of each tool in the toolchain.
[0067] Step 2: Based on the data of the steel wire, winch, and tool string, determine the motion relationship between each pair of the tool string, steel wire, and winch.
[0068] Step 3: Construct a work process model based on the historical motion data and motion relationships of the steel wire.
[0069] In this step, by utilizing the historical motion data and motion relationships of the wire, the corresponding historical motion data of the winch and the tool string can be calculated. Based on the historical motion data of the wire, the historical motion data of the winch, the historical motion data of the tool string, and the attribute information of the three, a work process model is constructed.
[0070] The embodiments disclosed herein utilize a work process model and a wire work scenario to achieve real-time animation simulation of wire work.
[0071] 202. The third screen is displayed based on multiple working equipment models, including wellhead tool model, well body model, winch model, wire model, and tool string model.
[0072] The third screen displays a three-dimensional graphic of the target oil and gas well operation system.
[0073] In this step, models of various operating equipment are used to construct a complete scenario of the target oil and gas well, displaying a 3D graphic of the entire operating system of the target oil and gas well on the monitor. The third screen can display the wellhead equipment and the internal structure of the wellbore. Any part can be zoomed in by clicking on the touch screen, so that the operator can know the status of any equipment in the entire wireline operation scenario in real time.
[0074] 203. Receive a request for partial enlargement of the target oil and gas wellbore.
[0075] In this step, the operator clicks on the location of the target oil and gas well on the display screen, triggering a local zoom-in request for the target oil and gas well. The full-scene wireline operation navigation system receives this local zoom-in request.
[0076] 204. In response to a zoom-in request, display the first screen.
[0077] This disclosed embodiment can not only display the entire scene of wire rope operation on the monitor, but also magnify local locations within the entire scene, flexibly demonstrating each step of the wire rope operation to the operator.
[0078] 205. Obtain the current wireline operation data for the target oil and gas well.
[0079] The execution content of this step is the same as... Figure 1 The specific details of step 103 in the illustrated embodiment will not be repeated here.
[0080] 206. Update the first screen using the wire rope operation data and operation process model to obtain the second screen.
[0081] The execution content of this step is the same as... Figure 1 Step 104 of the illustrated embodiment will not be described in detail here.
[0082] 207. Determine the target location using wireline operation data, operation process model, and wellbore model.
[0083] The target location is the current position of the tool string inside the wellbore.
[0084] In this step, the target location can be determined using wireline operation data, operation process model, and wellbore model, or it can be determined based on the second screen by the positional relationship between the wellbore and the target tool string.
[0085] 208. Based on the target position, predict the job limit situation of the tool string to obtain the current job limit information of the tool string.
[0086] The operational limit information includes the maximum speed and maximum depth of the tool string, as well as the upward force of each tool in the tool string.
[0087] This embodiment of the invention can not only display the real-time position of the target tool string in the wellbore, but also display the current working limit information of the tool string in the second screen. By using the estimated working limit information, the operator can perform wireline operations more smoothly, thereby improving the reliability and safety of the operation.
[0088] The upward force of each tool in the toolchain, and the formula for the upward force is:
[0089]
[0090] Among them, V g The volume of the tool is in cm. 3 ,ρ p The density of the liquid inside the wellbore is given in g / cm³. 3 α is the current well inclination angle, in degrees.
[0091] In one feasible approach, the maximum ingress depth of the target toolchain can be obtained through the following steps:
[0092] Step 1: Calculate the current friction force of the tool string.
[0093] Step 2: Based on the target location and wellbore model, determine the target vertical well section along the longitudinal direction of the wellbore.
[0094] The starting point of the target vertical well section is the target location.
[0095] Step 3: Determine the maximum running depth based on the length of the target vertical well section, the length of the tool string, and the friction force.
[0096] The maximum depth of penetration is obtained in the following way:
[0097] (1) Determine cosα a×G g >F,
[0098] If so, X s = No restrictions. If not, proceed to step (2).
[0099] Among them, X s The maximum depth is given in meters (m); α a , where is the horizontal well inclination angle, in °; Gg is the tool weight, in N; F is the friction force, in N.
