Abstract
Description
Technical Field
[0001] The present application relates to the field of soluble bridge plug dissolution test equipment, and in particular to a soluble bridge plug circulation test device and method. Background Art
[0002] Fracturing is an important part of the natural gas and shale gas extraction process. The quality of fracturing will play a vital role in the subsequent natural gas production. The performance of soluble bridge plugs is a key tool to determine the success of fracturing. The performance test of soluble bridge plugs mainly involves three groups of test processes: setting and releasing, high temperature pressure resistance and high temperature dissolution. Through the above equipment tests, the dissolution time of soluble bridge plugs in the flowing mineralization solution state can be fully mastered.
[0003] First, at present, there are many types of devices used for soluble bridge plug performance testing, mainly including underground test wells and ground pressure pumps. Although the above devices can complete the soluble bridge plug test process, they all have several common problems:
[0004] First, it is impossible to simulate the dissolution process of the soluble bridge plug under the flow conditions of the bottom hole fracturing fluid;
[0005] Second, it is impossible to observe the dissolution state and rate of the soluble bridge plug and conduct a more in-depth study on the soluble bridge plug;
[0006] Third, it cannot simulate the dissolution of bridge plugs under high temperature and high pressure conditions underground.
[0007] Among them, there are many types of soluble bridge plugs at present, and the alloy composition is also different. The time for the bridge plugs of each manufacturer to dissolve on site is not the same, which may easily cause other operations to start before the dissolution is complete in the well, causing blockage in the well.
[0008] Moreover, different manufacturers currently lack the real completion time of dissolution of soluble bridge plugs, and only have an approximate completion time of dissolution, which cannot accurately grasp the completion time of dissolution of soluble bridge plugs. Moreover, the current soluble bridge plug dissolution equipment can only simulate the dissolution situation under static state, and cannot simulate the dissolution of soluble bridge plugs by flowing mineralized solution in the well.

[0093] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.
[0094] Taking into account the current inability to simulate the dissolution process of soluble bridge plugs under the flow conditions of bottom hole fracturing fluid, the inability to observe the dissolution state and rate of soluble bridge plugs, the inability to conduct more in-depth research on soluble bridge plugs, and the inability to simulate the dissolution of bridge plugs under high temperature and high pressure conditions downhole, the present application provides a soluble bridge plug circulation test device and method, which simulates the downhole operating environment of oil and gas fields through circulation, accurately reflects the operating process of soluble bridge plugs in oil and gas fields, structurally solves the contradiction between the dual value changes of temperature and pressure, and meets the functional requirements of the conditions required for the test.
[0095] In order to simulate the downhole operating environment of the oil and gas field through the circulation action and accurately reflect the operation process of the soluble bridge plug in the oil and gas field, the present application provides an embodiment of a soluble bridge plug circulation test device for realizing all or part of the contents of the soluble bridge plug circulation test method, and the soluble bridge plug circulation test device specifically includes a circulation pump, a circulation pipeline, a circulation visual connector, a circulation casing, a filter device and a circulation storage tank;
[0096] The circulation pump is connected to the circulation tank through the circulation pipeline, and the circulation pump is used to transport the mineralization solution to the circulation tank;
[0097] The circulation sleeve is arranged between the circulation pump and the circulation storage tank, and the circulation visual connector is connected to the circulation sleeve;
[0098] The filtering device is arranged between the circulation casing and the circulation storage tank;
[0099] The circulation pump and the circulation pipeline are connected by a loose joint via a union;
[0100] Wherein, the filtering device is the outlet filtering device of the circulation pipeline, which is used to remove metal particles in the mineralization solution through multi-stage filtration;
[0101] The circulation storage tank has a heating function and is used to store the mineralization solution;
[0102] The circulating pump has a pressure boosting function.
[0103] Specifically, since the soluble bridge plug will generate metal particles when it is dissolved in the mineralization solution, the metal particles will gradually mix into the solution, causing the specific gravity of the solution to gradually increase. If the metal particles are not effectively removed, they may have an adverse effect on the circulation pump in the entire system and shorten its service life. Therefore, through the multi-stage filtration device, the dissolved metal particles can be gradually separated and removed, thereby ensuring the long-term stable operation and service life of the system. Preferably, the filtration device is designed as a multi-stage filtration system.
[0104] The circulating tank is used to store the salinity solution. The tank has not only a storage function but also a heating function. As the temperature gradually rises during the test, the pressure in the tank will also gradually increase, so as to better simulate the pressure circulation dissolution process of the soluble bridge plug at the bottom of the well, which is helpful to study the performance of the soluble bridge plug more realistically.
[0105] The circulation pump is a key component for circulating the pressurized salinity solution in the storage tank. It has a pressurization function, that is, it can push the solution to flow with sufficient pressure. It ensures that during the test, the salinity solution can circulate under high temperature and high pressure conditions, thereby promoting the dissolution of the soluble bridge plug. The function of the circulation pump makes the test conditions closer to the actual operating environment.
[0106] Optionally, the circulation visual connector and the circulation pipeline are both liquid-tight via a radial sealing ring.
[0107] Optionally, the circulation pipeline is insulated to reduce heat loss during operation.
[0108] Optionally, the circular visual connector is made of a material that shields refracted light, which is more conducive to observing the dissolution state of the soluble bridge plug.
[0109] Optionally, the pump head of the circulation pump is made of stainless steel, which has higher protection performance for the mineralized solution.
[0110] Optionally, the circulation sleeve and the circulation visual connector are arranged in a sleeve placement box, a filter is arranged in the circulation sleeve, and a test workpiece is also arranged in the sleeve placement box.
[0111] Optionally, the circulation pipeline is provided with a pressure sensor and a temperature sensor, and the pressure sensor and the temperature sensor are used to collect operating parameters of the device.
[0112] Optionally, an online magnesium ion monitor is provided between the filtering device and the circulation casing, and the online magnesium ion monitor is used to monitor the concentration of magnesium ions in the mineralization solution.
[0113] A chloride ion online monitor is arranged between the circulation pump and the circulation casing, and the chloride ion online monitor is used to monitor the concentration of chloride ions in the mineralization solution.
[0114] Optionally, a replenishment pump is provided between the filtering device and the circulation storage tank, and the replenishment pump is used to control the chloride ion concentration of the reaction mineralization solution so as to keep the chloride ions of the solution participating in the reaction at a constant value.
[0115] Optionally, the device is externally connected with a programmable logic controller, a touch display screen, a circulation flow meter and a frequency converter;
[0116] The programmable logic controller is used to monitor and control the operating status of the device;
[0117] The touch display screen is used to adjust the operating parameters of the control device;
[0118] The circulation flow meter is used to monitor the instantaneous flow of the mineralization solution in the circulation pipeline;
[0119] The frequency converter is used to control the motor speed of the circulation pump.
[0120] Specifically, the programmable logic controller monitors and controls the operating state, the touch screen displays and adjusts the operating parameters, the circulation flow meter monitors and displays the instantaneous flow of the solution in the circulation pipeline, and the frequency converter controls the speed of the pump motor to achieve the purpose of regulating the flow, and the whole process forms a closed-loop control.
[0121] In addition, the circulation storage tank is integrated with major automatic control components, which can control the system pressure within a safe range according to pressure changes.
[0122] Optionally, the circulating tank is provided with a circulating liquid level meter, which is connected to the circulating tank via a circulating pipeline connection flange and is used to monitor the remaining amount of the mineralization solution in the circulating tank, and the liquid level meter is connected to the circulating tank via a flange. The liquid level meter described in this application is capable of observing the liquid level of the solution in the circulating tank, withstands the corrosion of the mineralization solution, and truly reflects the liquid level in the circulating tank.
[0123] Optionally, the circulating storage tank is provided with a circulating self-releasing valve, which is connected to the circulating storage tank via a thread and is used for automatically releasing pressure after detecting that the pressure of the circulating storage tank reaches a set pressure. The circulating self-releasing valve can prevent the internal pressure of the system from exceeding the rated values of the circulating storage tank and the circulating pipeline. After the pressure in the circulating storage tank reaches the set pressure, it is automatically released to ensure stable operation of the system.
[0124] Preferably, the circulating self-release valve is sensitive and can discharge quickly after reaching the set pressure, thereby maintaining the safety of circulating use.
[0125] Optionally, the circulation storage tank is provided with a circulation drain valve, and the circulation drain valve is connected to the circulation storage tank via a thread, so that the drain device after use is used to control the discharge of the liquid after the circulation is completed.
[0126] Preferably, the circulating sewage valve can withstand circulating high temperature and high pressure media, so that when discharging waste liquid, the sealing performance of the valve cannot cause damage to the device due to residues.
[0127] Optionally, a circulation heater is provided in the circulation storage tank, and the circulation heater is used to provide a heat source for the device.
[0128] It can be seen from the above description that the soluble bridge plug circulation test device provided in the embodiment of the present application adopts the structure of a circulation tank and a circulation pump to simulate the environment of downhole operations in oil and gas fields.
[0129] In a closed-loop control system, a rise in temperature will inevitably lead to a rise in pressure; the existence of system pressure will affect the boiling point of the liquid in the closed-loop system. This solution structurally solves the contradiction between the dual value changes of temperature and pressure and meets the functional requirements of the conditions required for the test.
[0130] The present application provides a high-temperature and high-pressure soluble bridge plug circulation test device and test method, which simulates the downhole operating environment of oil and gas fields through circulation, and accurately reflects the operation process of soluble bridge plugs in oil and gas fields. The circulation visual connector is connected to the test workpiece through a circulation pipeline. During the test, the dissolution state of the soluble bridge plug can be visually observed. The circulation pump fills the mineralization solution into the circulation tank. The system uses a circulation heater to gradually increase the temperature. The mineralization solution flows and the mineralization solution heats up simultaneously. Under the flow flushing and pressure conditions of the mineralization solution, the complete bridge plug will gradually become small pieces as the reaction proceeds and flow with the circulating liquid. The present application uses a filtering device to prevent small pieces of bridge plugs from entering the circulation pipeline and causing blockage, so that the small pieces of bridge plugs will continue to react in the solution until they are completely dissolved in the solution.
[0131] In order to further illustrate the present solution, the present application also provides a specific application example of using the above-mentioned soluble bridge plug cycle test device to implement a soluble bridge plug cycle test method, which specifically includes the following contents:
[0132] Figure 1 This is a structural diagram of an embodiment of the present application. The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiment is only a part of the embodiment, not all of it. Based on the embodiment in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.
[0133] As shown in the figure, the embodiment of the present application includes a circulation storage tank 24, a circulation pump 1, a circulation visual connector 2, a test workpiece 11, circulation pipelines 4 and 13, a filtering device 5, a circulation self-release valve 6, a circulation heater 25, a circulation liquid level meter 8, a circulation drain valve 9, a circulation storage tank 24, solenoid valves 17, 19, 21 and 7, temperature sensors 16 and 18, a pressure sensor 15, a circulation flow meter 22, a chloride ion online monitor 20, a circulation sleeve 3, a sleeve placement box 12, a circulation pipeline connecting flange 10, a touch screen 26, a programmable logic controller 27, a frequency converter 28, a magnesium ion online monitor 30, and a rehydration pump 23.
[0134] The outlet of the circulation pump 1 is connected to the circulation visual connector 2 through the circulation pipeline 14. The outlet end of the circulation pump 1 is a flange, and one end of the circulation pipeline 14 is a liquid level flange, and the two flanges are sealed by a sealing gasket. The circulation visual connector 2 is a threaded connection, and one end of the circulation pipeline 4 is a thread, and the sealing is achieved by the thread and the sealing packing.
[0135] The circulation visual connector 2 is connected with the circulation sleeve 3. The circulation sleeve 3 is designed with external threads and a sealing end, and the circulation visual connector 2 is provided with internal threads and a sealing rubber ring, and the sealing box is self-locked through the threaded connection.
[0136] The circulation sleeve 3 is connected to the circulation storage tank 24 through the circulation pipeline 4 and the filter device 5. The filter device 5 is designed with internal threads, and the circulation pipeline 4 is sealed by threads and fillers. The circulation storage tank 24 is provided with a liquid inlet flange at the lower end, and the mineralization solution flowing through the circulation sleeve 3 enters the circulation storage tank 24 from the lower end.
[0137] The circulation tank 24 is connected to the inlet of the circulation pump 1 through the circulation pipeline 13. The high-end outlet of the circulation tank 24 is designed with a flange, which is connected to the inlet of the circulation pump 1 through the circulation pipeline, so that the clean mineralized liquid can be circulated by gravity.
[0138] A circulation heater 25 is installed in the circulation tank 24. The circulation heater 25 is fixed inside the circulation tank 24, and can fully heat the mineralization solution when it flows from low to high, and can also prevent the influence of dry burning on the circulation heater 25.
[0139] The filter screen 29 is fixed inside the circulation sleeve 3 , and the mesh of the filter screen 29 is dense, which can prevent the test workpiece 11 from moving along the flow direction of the liquid and blocking the circulation pipeline 4 .
[0140] The circulation pipeline 13 and the circulation pipeline 4 are equipped with electromagnetic valves 17 and 19 at the liquid inlet and outlet of the circulation tank 24. The electromagnetic valves can be closed before the sleeve is disassembled to prevent the liquid in the circulation tank 24 from flowing out.
[0141] The chloride ion online monitor 20 is connected to the circulation pipeline 14 via the solenoid valve 21. After the solenoid valve 21 is opened, the liquid in the circulation pipeline 14 flows into the chloride ion online monitor 20, and the chloride ion concentration can be monitored.
[0142] The circulation flow meter 22 is installed on the circulation pipeline 14 at the outlet of the circulation pump 1. The real-time flow rate and the accumulated flow of the solution can be viewed through the dial of the circulation flow meter 22.
[0143] The temperature sensors 16 and 18 can monitor the temperature of the solution flowing into the circulation tank 24, and the temperature sensor 16 can monitor the temperature of the solution flowing out of the circulation tank 24. The signals of the sensors are sent to the programmable logic controller 27 and can be displayed on the touch screen 26.
[0144] The pressure sensor 15 can measure the pressure in the tank. When the pressure exceeds the set pressure, the solenoid valve 7 can be opened to exhaust gas to reduce the tank pressure to prevent overpressure. When the exhaust gas reaches the set lower limit of the pressure, the solenoid valve is closed.
[0145] When the pressure sensor 15 and the solenoid valve 7 fail and the pressure in the circulation tank 24 exceeds the set pressure of the circulation self-release valve 6, the circulation self-release valve 6 opens to discharge the pressure, so that the pressure in the circulation tank 24 does not exceed the design pressure, thereby ensuring the safe operation of the equipment.
[0146] The magnesium ion online monitor 30 can monitor the content of magnesium ions in the solution. At the beginning of the test, the concentration of the magnesium ion solution is zero. As the bridge plug dissolves, the magnesium ion content becomes higher and higher. After the bridge plug is dissolved, the magnesium ion concentration does not change. If the magnesium ion concentration does not change, it can be determined that the dissolution of the soluble bridge plug is complete.
[0147] After the chloride ion online monitor 20 detects that the chloride ion concentration exceeds the variation range, the rehydration pump 23 can add new solution to adjust the concentration of the solution in the circulation tank so that the concentration of the solution participating in the reaction is maintained at a constant value.
[0148] The circulating sewage valve 9 is connected to the circulating storage tank 24 by threads. The circulating sewage valve 9 is a sewage discharge device of the system and an indispensable part of the closed-loop system.
[0149] On the other hand, in order to simulate the downhole operating environment of the oil and gas field through the circulation action, accurately reflect the operation process of the soluble bridge plug in the oil and gas field, solve the contradiction between the temperature and pressure dual value changes from the structural point of view, and meet the functional requirements of the test conditions, the present application provides an embodiment of the soluble bridge plug circulation test method, see Figure 2 The soluble bridge plug cycle test method specifically includes the following contents:
[0150] Step S101: collecting and storing chloride ion concentration via the chloride ion online monitor at preset time intervals.
[0151] According to the preset time interval, the current chloride ion concentration is collected and recorded by the chloride ion online monitor. The steps are continuous and used to monitor the change of chloride ion concentration in the solution during the dissolution process.
[0152] Step S102: in response to the chloride ion online monitor detecting that the chloride ion concentration is lower than a preset concentration range, controlling the fluid replenishment pump to replenish fluid until the chloride ion concentration is within the preset concentration range.
[0153] Once the chloride ion online monitor detects that the chloride ion concentration is lower than the preset concentration range, the system will automatically respond and start the refill pump. The refill pump will increase the chloride ion in the solution until the chloride ion concentration returns to the preset range. This ensures that the key chemical parameters in the test are maintained at the appropriate level.
[0154] Step S103: In response to receiving the flow control instruction, controlling the frequency converter to adjust the speed of the circulation pump motor until the instantaneous flow in the circulation pipeline is within the target flow range.
[0155] The system also has a flow control function. If the system receives a flow control command, it adjusts the speed of the circulation pump motor to ensure that the instantaneous flow in the circulation pipeline remains within the target flow range, which helps to achieve accurate control and stability of the test parameters.
[0156] Step S104: in response to the temperature sensor detecting that the temperature of the mineralization solution exceeds a preset temperature range, controlling the circulation heater to reduce power or shut down until the temperature of the mineralization solution is within the preset temperature range.
[0157] The outlet temperature sensor of the circulating tank detects the outlet solution temperature. When the set temperature is reached, the heating is reduced or stopped. The temperature control forms a closed-loop control to achieve the purpose of precise temperature control.
[0158] Step S105: In response to receiving the abnormal signal, controlling the device to stop working and issuing a warning signal.
[0159] Preferably, the programmable logic controller immediately stops the test and issues an audible and visual alarm upon detecting a system abnormality, and the test can be continued after the fault is eliminated.
[0160] The present application provides a high-temperature and high-pressure soluble bridge plug circulation test device and test method. By setting parameters before the test starts, the system automatically runs according to the set parameters, and the chloride ion monitor collects the mineralization solution at the set interval time to monitor the change of chloride ions in the solution. The pressure, temperature, flow, running time and chloride ion concentration data are stored in the programmable controller and can be displayed in a curve on the touch screen. When an abnormality occurs, the programmable logic controller can automatically pause the test and record the cause of the fault. The test can be continued after the fault is eliminated.

[0172] Figure 4 FIG. 9 is a schematic block diagram of the system structure of the electronic device 9600 according to an embodiment of the present application. Figure 4 As shown, the electronic device 9600 may include a central processor 9100 and a memory 9140; the memory 9140 is coupled to the central processor 9100. It is worth noting that Figure 4 is exemplary; other types of structures may also be used to supplement or replace this structure to implement telecommunication functions or other functions.
