Description

Technical Field

[0001] This invention relates to the field of oil packer technology, specifically to an oil extraction deformation type oil packer. Background Technology

[0002] During oil extraction, fluids in the well may need to be isolated from different formations, pipelines, or equipment to prevent cross-contamination, fluid leakage, or disordered flow. This requires the use of oil packers for sealing and isolation.

[0003] Common oil packers typically employ fixed dimensions and material designs to operate within specific temperature and pressure ranges, requiring manual operation by personnel to achieve sealing and closure.

[0004] Considering that oil packers are typically used in oil wells, and the external temperature in oil wells can change, if the elasticity and tension of the oil packer do not change after the external temperature changes, the long-term sealing performance of the oil packer will be affected. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a deformable oil packer for oil extraction, which solves the problem that the long-term sealing performance of the oil packer is affected when the external temperature in the oil well changes and the elasticity and tension of the oil packer remain unchanged.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deformable oil packer for oil extraction, comprising a central tube, a pneumatic expansion device fixedly connected to the outer wall of the central tube, a control system fixedly connected to the outer wall of the central tube, an upper connector fixedly connected to the top of the central tube, an oil injection pipe fixedly connected to the top of the upper connector, a lower connector fixedly connected to the bottom of the central tube, and a sensor fixedly connected to the outer wall of the central tube. The control system includes a sensing and monitoring module, which monitors the ambient temperature and performance data of the device, including the elasticity and tension of the oil packer, and records and stores the collected and monitored data. The measured data is transmitted to the adaptive adjustment module. The adaptive adjustment module is connected to the sensing and monitoring module. The adaptive adjustment module receives and reads the data transmitted by the sensing and monitoring module, and automatically selects appropriate adjustment parameters according to the different data. The selected adjustment parameters are then transmitted to the deformation control module. The deformation control module receives the adjustment parameters transmitted by the adaptive adjustment module and adjusts the elasticity and tension of the oil packer appropriately according to the adjustment parameter data. This ensures that the elasticity and tension of the oil packer meet the requirements of the external ambient temperature, improving the adaptability of the oil packer while ensuring that the sealing effect of the oil packer is not affected by the external temperature over a long period of time.

[0007] Preferably, the adaptive adjustment module includes an identification receiving module and a parameter standard module. The identification receiving module receives and reads the data monitored and collected by the sensing monitoring module, and transmits the read data to the comparison and selection module. The identification receiving module is connected to the comparison and selection module. The comparison and selection module receives the data transmitted by the identification receiving module and, based on the data values, extracts different parameter standards recorded and stored in the parameter standard module through the reading module. After reading the parameter standards, it compares them with the received data, selects the corresponding parameter standard, and transmits it to the deformation control module. The comparison and selection module is connected to the parameter standard module through the reading module. The parameter standard module records and stores the elasticity and tension values ​​that the oil packer needs to maintain and adjust at different temperatures. The identification receiving module is connected to the sensing monitoring module, and the comparison and selection module is connected to the deformation control module. The deformation control module receives the parameter standard data selected from the comparison and selection module and adjusts the elasticity and tension of the oil packer appropriately according to the parameter standard values ​​to achieve the purpose of adaptive adjustment.

[0008] Preferably, the identification receiving module includes a high-temperature identification module, a normal-temperature identification module, and a low-temperature identification module;

[0009] The high temperature identification module records values ​​above 60 degrees Celsius. When the identification receiving module receives the ambient temperature transmitted by the sensing and monitoring module, if the ambient temperature exceeds 60 degrees Celsius, the high temperature identification module will determine that the environment is in a high temperature state.

[0010] The value recorded in the ambient temperature identification module is between 15 and 60 degrees Celsius. When the identification receiving module receives the ambient temperature transmitted by the sensing and monitoring module, if the ambient temperature is between 15 and 60 degrees Celsius, the ambient temperature identification module will determine that it is in a normal temperature state.

[0011] The low-temperature identification module records values ​​below 15 degrees Celsius. When the identification receiving module receives the ambient temperature transmitted by the sensing and monitoring module, if the ambient temperature is below 15 degrees Celsius, the low-temperature identification module will determine that the environment is in a low-temperature state.

[0012] Preferably, the high-temperature identification module, the room-temperature identification module, and the low-temperature identification module are all connected to the comparison and selection module. This allows the high-temperature identification module, the room-temperature identification module, and the low-temperature identification module to determine the ambient temperature and then transmit the determined temperature value to the comparison and selection module. This facilitates the comparison and selection module in selecting the corresponding parameter standard based on the ambient temperature value. The parameter standard module includes a high-temperature parameter module, a room-temperature parameter module, and a low-temperature parameter module.

[0013] Preferably, the ambient temperature parameter module records that when the ambient temperature is maintained between 60 degrees Celsius and 15 degrees Celsius, the elastic adjustment percentage of the oil packer decreases by 5% to 15%, while the tension adjustment percentage increases from 5% to 5%.

[0014] The high-temperature parameter module records that when the ambient temperature exceeds 60 degrees Celsius, the elastic adjustment percentage of the oil packer decreases by 15% to 25%, while the tension adjustment percentage increases by 10% to 20%.

[0015] The low-temperature parameter module records that when the ambient temperature is below 15 degrees Celsius, the elastic adjustment percentage of the oil packer increases from constant to 10%, while the tension adjustment percentage decreases by 10% to constant.

[0016] Preferably, the high-temperature parameter module, the normal-temperature parameter module, and the low-temperature parameter module are uniformly connected to the comparison and selection module, and the comparison and selection module selects the corresponding parameter module according to the external ambient temperature.

[0017] Preferably, the sensing and monitoring module includes an ambient temperature sensing module and a storage and recording module. The ambient temperature sensing module measures the temperature outside the oil packer. The storage and recording module is connected to a performance monitoring sensing module, which monitors the elastic and tensile properties of the oil packer, facilitating the observation of the packer's parameter data by staff. Simultaneously, it works with the storage and recording module to store and record the packer's parameter performance data. The storage and recording module is connected to the ambient temperature sensing module, and after the ambient temperature sensing module measures the temperature, it transmits the temperature data to the storage and recording module for storage, facilitating later analysis and viewing.

[0018] Preferably, the deformation control module includes a tension control module and an elasticity control module. The tension control module is used to adjust the tension performance of the oil packer to ensure that an appropriate tension level is maintained under different working conditions. Both the tension control module and the elasticity control module are connected to the comparison selection module.
