Description

Technical Field

[0001] The present application relates to petroleum engineering technology, and in particular to a data processing method and a testing device. Background Art

[0002] In current petroleum engineering, fracturing tests can be performed in the environment of oil wells, but data during the fracturing test cannot be collected, nor can data processing be performed on the data during the fracturing test to optimize the fracturing test. Existing flow management methods have technical problems such as being unable to collect data during the fracturing test and being unable to optimize the fracturing test.

[0003] In the current petroleum engineering context, downhole fracturing testing faces the following technical problems:

[0004] 1. Lack of data collection: Existing technologies make it difficult to collect key data such as pressure and temperature in real time during fracturing tests. This leads to incomplete data and makes it impossible to fully understand the changes in the downhole environment during the fracturing process, especially in high-temperature and high-pressure downhole conditions, where the performance of existing sensors often fails to meet the requirements.

[0005] 2. Insufficient data processing capabilities: Even if some data acquisition devices can record data, existing equipment lacks the ability to analyze and process data in real time. Due to the complex downhole environment, the validity and timeliness of data are required to be high, and the current system is difficult to achieve real-time analysis and feedback, which limits the optimization and adjustment of fracturing effects.

[0006] 3. Lack of adaptive trigger mechanism: Most existing flow management systems adopt fixed data collection methods and lack a mechanism to automatically trigger data recording based on downhole pressure and temperature. This design cannot flexibly adjust the collection parameters for different downhole conditions, resulting in insufficient test data accuracy and affecting the evaluation of the effect of fracturing tests.

[0007] 4. Difficulty in recovery and maintenance: After the fracturing test device is used in a high-pressure environment, the recovery process is complicated and maintenance is difficult. In particular, due to the limitations of downhole conditions, it is difficult for existing devices to achieve an effective integrated design of plugging, detection, and recovery. Most equipment cannot be recovered or reset after the test is completed, which makes the reuse rate of the device low and increases the operating cost.

[0008] 5. Insufficient optimization of the test process: The current equipment lacks the function of further optimizing and analyzing the test data, making it difficult to adjust the fracturing parameters according to the real-time data to obtain the best recovery effect. The lack of optimization means that the value of the data after the test has not been fully tapped, affecting the overall benefits of the fracturing technology.

[0009] The existence of these problems makes the current downhole fracturing testing lacking in data collection, analysis, equipment recovery and process optimization, limiting the further development of fracturing technology in petroleum engineering. Summary of the invention

[0039] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0042] The processing flow of the data processing method provided in the embodiment of the present application is described. Figure 1 , Figure 1 The processing flow diagram of the data processing method provided in the embodiment of the present application is as follows: Figure 1 , will combine Figure 1 Steps S101-S104 are shown for explanation.

[0043] Step S101, obtaining environmental data of the environment in which the test device is located.

[0044] In some embodiments, the environmental data may include pressure data and temperature data. The environmental data may also include other data, which is not limited in the embodiments of the present application. The environment in which the test device is located may include: an underground working environment of an oil well. The oil well may include a linear well section and a horizontal well section. The test device may record environmental data in a chronological order in the oil well.

[0045] Step S102: Based on the test device, a fracturing test is performed on the environment in which the test device is located.

[0046] In some embodiments, the test device can be used to seal the environment in which the test device is located during a fracturing test. Fracturing testing can be a process used in the oil and gas industry to increase the production of oil and gas wells. During a fracturing test, high-pressure fluid is injected into the linear and horizontal sections of the oil well to create cracks in the horizontal sections, thereby increasing the permeability of the rock in each section of the oil well, allowing oil and gas to flow to the wellhead more easily.

[0047] Step S103, in response to the environmental data satisfying the set test conditions, recording the test data during the fracturing test process.

[0048] In some embodiments, the test data during the fracturing test may include: pressure test data and temperature test data measured during the fracturing test. The pressure test data may include: static pressure and dynamic pressure. The static pressure may include: the pressure of the environment in which the test device is located when there is no fluid flow. The dynamic pressure may include: the pressure of the environment in which the test device is located when there is fluid flow. The temperature test data may include: the temperature of the environment in which the test device is located during the fracturing test. The test conditions may include pressure test conditions and / or temperature test conditions. Meeting the pressure test condition may include: the pressure data of the environment in which the test device is located is greater than or equal to the pressure threshold, the pressure threshold may be a pre-set pressure value that can be used for fracturing test, or the pressure threshold may be a pre-set pressure range value that can be used for fracturing test. Meeting the temperature test condition may include: the temperature data of the environment in which the test device is located is greater than or equal to the temperature threshold, the temperature threshold may be a pre-set temperature value that can be used for fracturing test, or the temperature threshold may be a pre-set temperature range value that can be used for fracturing test.

[0049] Step S104, analyzing the test data to obtain the test results corresponding to the fracturing test.

[0050] In some embodiments, the test device can perform a time series analysis on the recorded test data to obtain the change trend of the pressure test data and the temperature test data over time during the fracturing test, and then perform an environmental parameter analysis on the change trend to obtain the test results corresponding to the fracturing test. The test data can also be transmitted to a computer and analyzed by the computer to obtain the test results corresponding to the fracturing test. Among them, the analysis can include: pressure analysis, flow analysis, optimization analysis and environmental parameter analysis. The analysis can also include other analyses, which are not limited in the embodiments of the present application.

[0051] The method of the embodiment of the present application can accurately collect temperature test data and pressure test data during the fracturing test through steps S101-S104, provide more accurate information support for petroleum engineering, and can analyze the temperature test data and pressure test data, effectively evaluate the plugging effect of the test device and the environmental status of the oil well, and obtain the test results. The test results can be used to optimize the fracturing test, improve the oil and gas recovery rate, and reduce the cost of petroleum engineering.

[0052] In some embodiments, the processing flow of the data processing method is shown as follows: Figure 2 ,like Figure 2 As shown, including:

[0053] like Figure 2 As shown, in step S103, in response to the environmental data satisfying the set test conditions, recording the test data during the fracturing test process may specifically include:

[0054] Step S201a, in response to the pressure data included in the environmental data satisfying the pressure test condition and the temperature data included in the environmental data satisfying the temperature test condition, determining that the test device reaches a set first test position.

[0055] In this embodiment, when the pressure data of the environment in which the test device is located is greater than or equal to the preset pressure threshold, and the temperature data of the environment in which the test device is located is greater than or equal to the temperature threshold, it can be determined that the test device has reached the predetermined first test position, and at this time, the fracturing test can be started or continued and the test data in the fracturing test process can be recorded. Among them, the pressure threshold can be a pre-set pressure value that can be used for fracturing test, and the pressure threshold can also be a pre-set pressure range value that can be used for fracturing test. The temperature threshold can be a pre-set temperature value that can be used for fracturing test, and the temperature threshold can also be a pre-set temperature range value that can be used for fracturing test. The first test position can include a test position set in the working environment of the oil well. The first test position can also include a pre-set test point or depth position. The pressure data corresponding to each test position can be the same, and the pressure data corresponding to each test position can also be different. The temperature data corresponding to each test position can be the same, and the temperature data corresponding to each test position can also be different.

[0056] In some embodiments, before step S201a, the method further includes: obtaining historical operating condition information; and determining pressure test conditions and temperature test conditions based on the historical operating condition information and the environmental data. The historical operating condition information may include historical operating condition information of the oil well environment. The operating condition information may include the highest pressure, the lowest pressure, the temperature record, and the chemical composition of the oil well fluid.

[0057] As an example, when testing the performance of a downhole oil well bridge plug, the operating records of the oil well in the past year were first extracted from the database, including historical operating information such as the highest pressure, lowest pressure, temperature, and fluid type. After analyzing the environmental data and historical operating information, the pressure test condition was determined to be a maximum pressure of 30MPa; at the same time, based on the historical highest temperature record, the temperature test condition was determined to be a maximum temperature of 200℃.

[0058] Step S201b: in response to the pressure data included in the environmental data satisfying the set pressure test condition, determining that the test device reaches the set first test position.

[0059] In this embodiment, when the pressure data of the environment in which the test device is located is greater than or equal to the preset pressure threshold, it can be determined that the test device has reached the predetermined first test position, and the fracturing test can be started or continued and the test data during the fracturing test can be recorded. The pressure test conditions can be adjusted based on the current working condition information. The current working condition information may include: wellhead pressure, bottom hole pressure, fluid type, equipment status, geological data, and temperature data.

[0060] Step S201c: in response to the temperature data included in the environmental data satisfying the set temperature test condition, determining that the test device reaches the set first test position.

[0061] In this embodiment, when the temperature data of the environment in which the test device is located is greater than or equal to the preset temperature threshold, it can be determined that the test device has reached the predetermined first test position, and the fracturing test can be started or continued and the test data during the fracturing test can be recorded. The temperature test condition can be adjusted based on the current working condition information.

[0062] Step S202, recording the test data of the first test position during the fracturing test.

[0063] In this embodiment, the test data of the first test position during the fracturing test can be recorded by the mainboard, memory and sensor included in the test device. The sensor is used to measure the pressure test data and temperature test data of the first test position in real time, and the mainboard can store the pressure test data and temperature test data in the memory.

[0064] The method of the embodiment of the present application can accurately collect temperature test data and pressure test data during the fracturing test through steps S201a-S202, provide more accurate information support for petroleum engineering, and can analyze the temperature test data and pressure test data, effectively evaluate the plugging effect of the test device and the environmental status of the oil well, and obtain the test results. The test results can be used to optimize the fracturing test, improve the oil and gas recovery rate, and reduce the cost of petroleum engineering.

[0065] In some embodiments, the processing flow of the data processing method is shown as follows: Figure 3 ,like Figure 3 As shown, including:

[0066] like Figure 3 As shown, the recording of the test data of the first test position during the fracturing test in step S202 may specifically include:

[0067] Step S301, in response to the test device arriving at a set first test position, determining a first time node for starting to record test data.

[0068] Step S302: Based on the first time node, record the test data of the first test position during the fracturing test process.

[0069] In this embodiment, the first time node may include: a time node at which the fracturing test is started. All recorded test data will be based on the first time node. Recording the test data of the first test position during the fracturing test may include: recording the pressure test data and the temperature test data during the fracturing test in the order of the time nodes.

[0070] As an example, in response to the test device arriving at a test position set in an underground working environment of an oil well, the mainboard of the test device will automatically trigger a start signal. The start signal indicates that the test device has arrived at the position. The start signal is used to trigger the recording of test data. The pressure test data and temperature test data of the test position during the fracturing test are recorded according to the time node corresponding to the triggered start signal. The test device stops recording test data until the test is completed or the preset test duration is reached.

[0071] The method of the embodiment of the present application can accurately collect temperature test data and pressure test data in the fracturing test process according to time nodes through steps S301-S302, monitor the changes of temperature test data and pressure test data over time in the oil well pressure test process, provide more accurate information support for oil engineering, and analyze the temperature test data and pressure test data, effectively evaluate the plugging effect of the test device and the environmental status of the oil well, and obtain the test results. The test results can be used to optimize the fracturing test, improve the oil and gas recovery rate, and reduce the cost of oil engineering.

[0072] In some embodiments, the processing flow of the data processing method is shown as follows: Figure 4 ,like Figure 4 As shown, including:

[0073] like Figure 4 As shown, the test data is analyzed in step S104 to obtain the test results corresponding to the fracturing test, which may specifically include:

[0074] Step S401 : in response to receiving a read instruction for test data, reading test data.

[0075] In this embodiment, the reading instruction may include: a reading instruction for test data from a mainboard of the test device. The reading instruction may also include: a reading instruction for test data issued by a computer. Reading test data may include: reading pressure test data and temperature test data during the fracturing test from a memory.

[0076] Step S402: Perform environmental parameter analysis on the test data to obtain the blocking capability of the test device and the environmental status of the test location.

[0077] In this embodiment, the sealing capability of the test device may include: the ability of the test device to prevent fluid leakage in a high-pressure environment in an oil well. The sealing capability may be determined by comprehensive evaluation of pressure test data and temperature test data. The environmental state of the test location may include: environmental parameters such as pressure, temperature and fluid properties corresponding to the test location. Environmental parameter analysis may include: calculating the pressure of the formation corresponding to the test location based on the pressure test data to determine the original energy state of the formation. Environmental parameter analysis may also include: analyzing the temperature test data to obtain the temperature change of the formation corresponding to the test location.

[0078] Step S403: determining the test result corresponding to the fracturing test based on the blocking capability and the environmental status.

[0079] In this embodiment, based on the blocking capacity and the environmental state, determining the test result corresponding to the fracturing test may include at least one of the following: inputting the blocking capacity and the environmental state into a prediction model to predict the production potential of the corresponding oil well. Comparing the environmental state with the environmental state before the fracturing test, and determining the fracturing effect after the fracturing test in combination with the blocking capacity. The fracturing effect can be used to characterize whether the fracturing test successfully improves the permeability of the formation under the oil well.

[0080] In some embodiments, after step S403, the method further includes: optimizing the fracturing test based on the test results corresponding to the fracturing test. Specifically, in a fracturing test of an oil well, the fracturing fluid formula and the pressure parameters of the test device are adjusted by analyzing the test results, including the fluctuation range of the bottom hole temperature and pressure. For example, based on the fact that the bottom hole temperature often exceeds 150°C and the pressure fluctuates between 20MPa and 30MPa, a fracturing fluid with better performance is determined and a temperature stabilizer is added. The optimal fracture spacing and pressure parameters are determined using an intelligent optimization algorithm.

[0081] The method of the embodiment of the present application can accurately collect temperature test data and pressure test data in the fracturing test process according to time nodes through steps S401-S403, monitor the changes of temperature test data and pressure test data over time in the oil well pressure test process, provide more accurate information support for oil engineering, and analyze the temperature test data and pressure test data, effectively evaluate the plugging effect of the test device and the environmental status of the oil well, and obtain the test results. The test results can be used to optimize the fracturing test, improve the oil and gas recovery rate, and reduce the cost of oil engineering.

After the fracturing test is completed, a chemical trigger can be injected into the environment of the oil well where the test device is located. In the environment after the chemical trigger is injected, the bridge plug body 1 can be dissolved, while the detection capsule 2 cannot be dissolved. For example, the bridge plug body 1 can be made of a soluble alloy material, and the detection capsule 2 can be made of a resin material that is resistant to high temperature, high pressure and corrosion.

The detection capsule 2 can be in a floating state in the liquid environment after release. The detection capsule 2 may include: a pressure sensor 21, a temperature sensor 22, a main board 23, a high-temperature battery 24, and a wireless charging module 25. Among them, the pressure sensor 21, the temperature sensor 22, the main board 23, the high-temperature battery 24, and the wireless charging module 25 are all arranged inside the detection capsule 2. The pressure sensor 21 is used to collect the pressure data of the environment in which the test device is located. The accuracy range of the pressure sensor 21 is 0 to 300 kpa. The temperature sensor 22 is used to collect the temperature data of the environment in which the test device is located. The accuracy range of the temperature sensor 22 is -300 ° C to 300 ° C. The main board 23 is connected to the pressure sensor 21 and the temperature sensor 22, and is used to receive the data collected by the pressure sensor 21 and the temperature sensor 22, and store these data in the memory. The main board 23 may include a single-chip microcomputer (MCU). A high temperature battery 24 is connected to the mainboard 23 and is used to power the mainboard 23. The high temperature battery 24 represents a battery that can power an environment above 85 degrees Celsius. A wireless charging module 25, one end of the wireless charging module 25 is connected to the high temperature battery 24, and the other end of the wireless charging module 25 is connected to the mainboard 23, and is used to wirelessly charge the high temperature battery 24. The wireless charging module 25 can specifically be a wireless charging module.

[0086] In some embodiments, the test device further includes: a groove 11, which is arranged on the surface of the bridge plug body 1, and the detection capsule 2 is fixedly connected to the groove 11. The groove 11 can be arranged at the upper end and the lower end of the bridge plug body 1. The surface of the bridge plug body 1 can be provided with a plurality of grooves 11, and each groove 11 can be fixedly connected to the detection capsule 2. Before the start of the fracturing test and during the fracturing test, the detection capsule 2 and the bridge plug body 1 cannot be dissolved, and the detection capsule 2 is fixedly connected to the groove 11. After the fracturing test is completed, a chemical trigger can be injected into the environment where the test device is located. In the environment after the chemical trigger is injected, the bridge plug body 1 can be dissolved, but the detection capsule 2 cannot be dissolved. The detection capsule 2 can be released, and the detection capsule 2 can be in a floating state in the liquid environment after the release.

[0087] In some embodiments, the detection capsule 2 may further include an infrared module, which may be used to start the detection capsule 2 to put the detection capsule 2 into a working state. The infrared module may also be used to interact with a computer to transmit pressure test data and temperature test data in a memory.

[0088] In the test device of this embodiment, the detection capsule 2 can accurately collect the temperature test data and pressure test data in the fracturing test process according to the time node, monitor the changes of the temperature test data and pressure test data over time in the pressure test process of the oil well, and provide more accurate information support for the oil engineering.

[0105] refer to Fig.11 , an application scenario diagram of the data processing method provided in the embodiment of the present application, which is applied to the fracturing test in an oil well. The oil well may include a vertical well section and a horizontal well section. The soluble bridge plug may include a bridge plug body and a self-floating microchip capsule. The self-floating microchip capsule is fixedly connected to the bridge plug body.

[0106] Step S1, placing a soluble bridge plug in the oil well, the self-floating microchip capsule responds to the pressure data included in the environmental data satisfying the set pressure test conditions, and the temperature data included in the environmental data satisfying the set temperature test conditions, to determine that the soluble bridge plug reaches the set test position, and the soluble bridge plug can get stuck to the well wall of the horizontal well section at the set test position.

[0108] Step S3, after the fracturing test is completed, a chemical trigger can be injected into the oil well, in which the bridge plug body and the soluble bridge plug ball can be dissolved, while the self-floating microchip capsule cannot be dissolved.

[0110] Step A1, start the detection capsule, and fix the detection capsule to the bridge plug body to form a test device. The detection capsule can be started by the infrared module of the detection capsule to put the detection capsule 2 into a working state. The bridge plug body is made of a soluble material, and the detection capsule is made of an anti-dissolution material.

[0111] Step A2, transporting the test device to the oil well, and moving the test device in the oil well. The test device can be moved in the horizontal well section and the vertical well section in the oil well, and the pressure data and temperature data corresponding to different positions in the oil well are different.

[0112] Step A3, based on the environmental data and the set test conditions, determine whether the test device has reached the set first test position. In response to the pressure data included in the environmental data satisfying the set pressure test conditions, and the temperature data included in the environmental data satisfying the set temperature test conditions, determine that the test device has reached the set first test position. In response to the pressure data included in the environmental data not satisfying the set pressure test conditions, and / or the temperature data included in the environmental data not satisfying the set temperature test conditions, determine that the test device has not reached the set first test position, and the test device can continue to be moved until it reaches the set first test position.

[0113] Step A4, recording the test data of the first test position during the fracturing test, wherein the test data may include pressure test data and temperature test data.

[0114] Step A5, after the fracturing test is completed, a chemical trigger can be injected into the environment where the test device is located, and after the bridge plug body is dissolved, the detection capsule is recovered. Among them, the bridge plug body can be dissolved in the environment after the chemical trigger is injected, but the detection capsule cannot be dissolved. The detection capsule can be released, and the detection capsule 2 can be in a floating state in the liquid environment after release. Under the combined effect of its own buoyancy and the flow force of the liquid in the oil well, the detection capsule can flow back to the ground.
