Description

Technical Field

[0001] The invention belongs to the technical field of bridge plugs, and in particular relates to a retrievable bridge plug which is convenient for setting and unsealing. Background Art

[0002] At present, traditional bridge plugs are used in the market. Traditional bridge plugs are usually set by ball-dropping and pressure-holding, hydraulic setting tools or gunpowder setting. Most of the setting tools are special tools. Ignition and setting involve the control and safety of industrial gunpowder, and the risk is relatively high. Hydraulic setting tools are traditional tools with long operation time, and a large amount of liquid needs to be injected during the process, resulting in large material loss. The supporting tools need to be replaced when the tool is recovered after setting, which takes a long time and increases the difficulty of the operation. Compared with other tools, the electronically controlled integrated setting tool no longer distinguishes between setting and unsealing tools.

[0003] The present invention adopts an integrated form of electric control setting and salvaging. After the tool string is sent into the well, it is directly set by electric control. There is no need to use a ball-dropping pressure method or an ignition method for setting, which reduces the operation time and cost. At the same time, the structure adopts an integrated design of setting and salvaging functions. Compared with the traditional sending and unsealing method, it reduces the tool replacement time, reduces the types of tools used, reduces the requirements for operators, reduces the operation time, and reduces the operation cost.

Compared with the traditional hydraulic sealing method of injecting a large amount of liquid, it does not need to inject a large amount of liquid, which helps to save a certain amount of material loss.

[0026] The present invention adopts an integrated form of electric-controlled setting, throwing and fishing. After the tool string is sent into the well, it is directly set by electric control. There is no need to use a ball-throwing pressure method or an ignition method for setting, thus reducing operation time and cost.

The main control board (9) has built-in complex control algorithms and logic to ensure the coordinated operation of various components; The electric drive board module enables the motor drive board (8) to receive instructions from the main control board (9) and provide appropriate drive current and voltage for the first high-temperature motor (12) and the second high-temperature motor (32). The electric drive board module is equipped with a current sensor and a temperature sensor. The current sensor is used to monitor the working current of the motor. When the current increases abnormally, it may indicate that the motor is overloaded or fails. The main control board (9) will stop the motor in time. The temperature sensor is used to monitor the working temperature of the motor. Excessive temperature may cause damage to the motor, and the protection mechanism will be triggered at this time. A first oil pump module, wherein the first oil pump (13) is driven by the first high-temperature motor (12) and is responsible for outputting oil to one side of the piston sleeve (26). A pressure sensor and a flow sensor may be installed at the outlet of the oil pump. The pressure sensor is used to monitor the pressure of the output oil to ensure that the pressure value required for setting is reached. The flow sensor is used to measure the output oil volume of the oil pump and provide feedback to the main control board so as to accurately control the setting process. A second oil pump module, wherein the second oil pump (33) is driven by a second high-temperature motor (32) and has the function of outputting oil to the other side of the piston sleeve (26) to achieve an unsealing and salvaging function. The monitoring method is similar to that of the first oil pump, and a pressure sensor and a flow sensor are provided to ensure that the pressure and flow of the output oil meet the requirements of unsealing and salvaging; The piston sleeve module, the piston sleeve (26) is a key component for realizing the setting and unsealing and salvaging functions. A displacement sensor is installed in the piston sleeve (26) to monitor the movement position and stroke of the piston. Through the feedback of the displacement sensor, the main control board can accurately determine the progress of setting or unsealing and salvaging, and make corresponding control adjustments; Sensor data processing and feedback module: the data collected by each sensor will be transmitted to this module for processing and analysis. The processed data will be presented to the operator in a clear and intuitive manner.
