Description

Technical fields:

[0001] This invention relates to a digital booster injection skid-mounted device based on integrated control. Background technology:

[0002] Skid-mounted equipment refers to a combination of equipment frame and overall equipment, consisting of multiple functional modules of different types, which can complete the configuration and output of the target fluid. Generally, each functional module in the skid-mounted equipment is controlled and adjusted individually by the operator. Through the interaction of the various functional modules, the configuration and output of the target fluid for the target well are completed.

[0003] Because existing booster injection skid-mounted equipment is not equipped with relevant integrated control digital devices, the relevant functional modules cannot be automatically controlled during the booster injection of polymer solution into the target well. The lack of corresponding linkage and coordination between the various functional modules affects the response rate of the booster injection process, which makes it impossible to guarantee the overall working efficiency and working accuracy of the booster injection skid-mounted equipment. This leads to deviations during the booster injection of polymer solution and fails to meet the actual application requirements of injecting the target fluid into the target well. Summary of the Invention:

[0004] This invention provides a digital booster injection skid-mounted device based on integrated control. With a reasonable structural design, the integrated control function of the digital control module enables automated adjustment of relevant functional modules during the booster injection of polymer solution into the target well. This allows multiple functional modules to cooperate in precisely controlling the input and output ends of the injection skid-mounted device, improving the response rate of the booster injection of polymer solution, enhancing the overall efficiency and accuracy of the skid-mounted device, avoiding deviations during booster injection, meeting the practical application requirements of booster injection into the target well, and solving the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A digital booster injection skid-mounted device based on integrated control, the booster injection skid-mounted device comprising:

[0007] The pressurized injection module, the number of which matches the number of target wells, ensures a one-to-one correspondence between the pressurized injection module and the target well; it includes a sampling valve, a safety valve, and a hydraulic injection pump. The sampling valve is located at the outlet of the hydraulic injection pump and is used to sample and test the polymer solution; the safety valve is located on the slurry outlet line of the hydraulic injection pump and is used to protect the hydraulic injection pump from overload and to protect the injection well from overpressure, working in conjunction with the hydraulic injection pump to inject the mixed polymer solution;

[0008] The digital control module is electrically connected to the pressurization injection module to automatically regulate and control it. It works in conjunction with a PLC control cabinet, pressure protection components, liquid level protection components, and oil temperature protection components to ensure the safe and stable operation of the equipment. The digital control module integrates a display unit and a software interface unit. The integrated display unit enables remote centralized control of the equipment via data card or wireless bridge transmission. The software interface unit allows for seamless switching between operation monitoring, manual / automatic control, parameter setting, and report statistics interfaces.

[0009] The hydraulic injection pump is equipped with an electromagnetic flow meter, a pressure transmitter, and a plug valve; the pressure transmitter is interlocked with the motor of the hydraulic injection pump to prevent the injection pressure from exceeding the wellhead pressure; the electromagnetic flow meter is used to detect and adjust the injection flow rate in real time; the hydraulic injection pump adopts frequency conversion control so that the injection volume is automatically adjusted according to the set value.

[0010] The digital control module can monitor each process of equipment operation in real time, display the overall status of system operation, and issue alarms when abnormalities occur.

[0011] The parameter setting interface allows you to input basic operating parameters for the device, which can automatically calculate the operating parameters of each part and operate according to the parameters. At the same time, you can set corresponding alarm values ​​as needed.

[0012] The pressurized injection module is connected to the online continuous curing equipment through a static mixer and a polymer solution transport path to input the fully cured polymer solution into the pressurized injection module.

[0013] The online continuous curing equipment includes multiple curing tanks employing a multi-stage continuous curing process. Each curing tank is equipped with a multi-stage stirring assembly, which uses fixed-frequency control or variable-frequency control to accelerate polymer curing and shorten curing time. By adjusting the stirring speed through variable-frequency control, the equipment ensures that the equipment can complete polymer curing while reducing the shearing effect of stirring on the polymer solution. Interconnected flow channels are formed between the chambers within the curing tanks, allowing the polymer solution to flow along a predetermined path, ensuring that the polymer achieves complete curing within the designed process time.

[0014] A diaphragm-type electronic level gauge is installed inside the curing tank, which can be set with high and low level protection thresholds to ensure that the liquid level in the curing tank is within a suitable range. The diaphragm-type electronic level gauge is installed in the first-stage curing tank, the intermediate curing tank, and the last-stage curing tank to ensure that the curing tank does not overflow or become emptied. At the same time, in conjunction with the digital control module, it can automatically calculate based on the polymer solution injection volume and the set curing time, determine the position of the last-stage curing tank, and automatically adjust the liquid level in the curing tank to change the polymer curing time under each polymer solution injection volume, ensuring that the curing time is neither too long nor too short.

[0015] During normal operation, any intermediate curing tank can be used as the final curing tank. By adjusting the position and liquid level of the final curing tank, the volume of the continuous curing tank can be adjusted, thereby changing the amount of solution in the curing tank and the curing time of the polymer solution to adapt to polymer solution mixing processes with different discharge rates and curing time requirements.

[0016] This invention employs the aforementioned structure, setting the number of booster injection modules to correspond one-to-one with the number of target wells, allowing each target well to be injected with a polymer solution of the required concentration. A digital control module is electrically connected to the booster injection modules for automated adjustment and control. The digital control module works in conjunction with a PLC control cabinet, pressure protection components, level protection components, and oil temperature protection components to ensure safe and stable equipment operation. Remote centralized control of the equipment is achieved through the transmission function of the integrated display unit. The software interface unit allows for seamless switching between the operation monitoring interface, manual / automatic control interface, parameter setting interface, and report statistics interface, offering advantages of precision, efficiency, safety, and practicality.

[0027] The pressurized injection module is connected to the online continuous curing equipment through a static mixer and a polymer solution transport path to input the fully cured polymer solution into the pressurized injection module.

[0028] The online continuous curing equipment includes multiple curing tanks employing a multi-stage continuous curing process. Each curing tank is equipped with a multi-stage stirring assembly, which uses fixed-frequency control or variable-frequency control to accelerate polymer curing and shorten curing time. By adjusting the stirring speed through variable-frequency control, the equipment ensures that the equipment can complete polymer curing while reducing the shearing effect of stirring on the polymer solution. Interconnected flow channels are formed between the chambers within the curing tanks, allowing the polymer solution to flow along a predetermined path, ensuring that the polymer achieves complete curing within the designed process time.

[0029] A diaphragm-type electronic level gauge is installed inside the curing tank, which can be set with high and low level protection thresholds to ensure that the liquid level in the curing tank is within a suitable range. The diaphragm-type electronic level gauge is installed in the first-stage curing tank, the intermediate curing tank, and the last-stage curing tank to ensure that the curing tank does not overflow or become emptied.

[0030] During normal operation, any intermediate curing tank can be used as the final curing tank. By adjusting the position and liquid level of the final curing tank, the volume of the continuous curing tank can be adjusted, thereby changing the amount of solution in the curing tank and the curing time of the polymer solution to adapt to polymer solution mixing processes with different discharge rates and curing time requirements.

[0031] The working principle of the digital booster injection skid-mounted equipment based on integrated control in this embodiment of the invention is as follows: Based on the integrated control function of the digital control module, the relevant functional modules can be automatically adjusted during the booster injection of polymer solution into the target well. This allows multiple functional modules to cooperate with each other to precisely control the input and output ends of the injection skid-mounted equipment, thereby improving the response rate of the booster injection of polymer solution, enhancing the overall working efficiency and accuracy of the skid-mounted equipment, avoiding deviations during the booster injection of polymer solution, and meeting the actual application requirements of booster injection into the target well.

[0032] In practical applications, the booster injection equipment is configured with the injection well. Since the injection requirements of different injection wells are different, relying on manual configuration by staff can easily lead to injection deviations and mismatches. Therefore, an integrated control digital configuration mode is needed to achieve precise booster injection for each target well.

[0033] In the overall solution, the pressurized injection skid-mounted equipment includes: a pressurized injection module, the number of which matches the number of target wells, ensuring a one-to-one correspondence between the pressurized injection module and the target well; a sampling valve, a safety valve, and a hydraulic injection pump, wherein the sampling valve is located at the outlet of the hydraulic injection pump for sampling and testing the polymer solution; the safety valve is located on the slurry outlet line of the hydraulic injection pump to protect the hydraulic injection pump from overload and the injection well from overpressure, and works in conjunction with the hydraulic injection pump to inject the mixed polymer solution; a digital control module, electrically connected to the pressurized injection module for automated adjustment and control of the pressurized injection module; the digital control module works in conjunction with a PLC control cabinet, pressure protection components, liquid level protection components, and oil temperature protection components to ensure the safe and stable operation of the equipment; and an integrated display unit and software interface unit within the digital control module, wherein the integrated display unit is used for remote centralized control of the equipment via data card or wireless bridge transmission; and the software interface unit allows for arbitrary switching between the operation monitoring interface, manual / automatic control interface, parameter setting interface, and report statistics interface.

[0034] To achieve automatic adjustment of the injection volume, the hydraulic injection pump adopts frequency conversion control; the hydraulic injection pump is equipped with an electromagnetic flow meter, a pressure transmitter, and a plug valve; the pressure transmitter is interlocked with the motor of the hydraulic injection pump to prevent the injection pressure from exceeding the wellhead pressure; the electromagnetic flow meter is used to detect and adjust the injection flow in real time, thereby ensuring that the hydraulic injection pump accurately controls the injection volume.

[0035] Generally, in the overall process of polymer solution preparation and output, under the integrated control of the digital control module, the pressurized injection module is connected to the online continuous curing equipment through the static mixer and polymer solution transmission path, and the fully cured polymer solution is input into the pressurized injection module.

[0036] The online continuous curing equipment includes multiple curing tanks employing a multi-stage continuous curing method. Each curing tank is equipped with a multi-stage stirring assembly. The multi-stage stirring assembly uses fixed-frequency control or variable-frequency control to accelerate polymer curing and shorten curing time. By adjusting the stirring speed through variable frequency, the equipment can ensure that the equipment can complete the polymer curing while reducing the shearing effect of stirring on the polymer solution. Interconnected flow channels are formed between the various chambers in the curing tank, allowing the polymer solution to flow along a predetermined route, ensuring that the polymer achieves complete curing within the process design time.

[0037] A diaphragm-type electronic level gauge is installed inside the curing tank, which can be set with high and low level protection thresholds to ensure that the liquid level in the curing tank is within a suitable range. The diaphragm-type electronic level gauge is installed in the first-stage curing tank, the intermediate curing tank, and the last-stage curing tank to ensure that the curing tank does not overflow or become emptied. At the same time, in conjunction with the digital control module, it can automatically calculate based on the polymer solution injection volume and the set curing time, determine the position of the last-stage curing tank, and automatically adjust the liquid level in the curing tank to change the polymer curing time under each polymer solution injection volume, ensuring that the curing time is neither too long nor too short.

[0038] During normal operation, any intermediate curing tank can be used as the final curing tank. By adjusting the position and liquid level of the final curing tank, the volume of the continuous curing tank can be adjusted, thereby changing the amount of solution in the curing tank and the curing time of the polymer solution to adapt to polymer solution mixing processes with different discharge rates and curing time requirements.

[0039] Furthermore, under the integrated control of the digital control module, the pressurized injection skid-mounted equipment of this application can also be used in conjunction with the continuous mixing pressurized feeding skid-mounted equipment and the surfactant injection skid-mounted equipment to accurately and efficiently complete the preparation and output of polymer solutions.

[0040] It should be noted that the digital control module can monitor each process of equipment operation in real time, display the overall status of system operation, and issue alarms when abnormalities occur. The parameter setting interface allows users to input basic operating parameters of the equipment, automatically calculate the operating parameters of each part, and operate according to the parameters. At the same time, corresponding alarm values ​​can be set as needed.

[0041] In summary, the digital booster injection skid-mounted equipment based on integrated control in this embodiment of the invention, based on the integrated control function of the digital control module, can automatically adjust relevant functional modules during the booster injection of polymer solution into the target well.
