Technical Field
The utility model relates to an oil gas well relief valve field in the pit especially relates to relief valve location detection instrument.
Background
Offshore oil and gas development is difficult, high in risk and complex in structure due to limited space of a production platform for management and development, so that the requirement on the safety of the mining process in the development process is very strict.
An oil and gas well downhole safety valve is one of the important downhole tools for ensuring the safe production of oil and gas wells. The underground safety valve is an underground safety control tool which is connected with a production pipe column through a hydraulic control switch. Generally comprises an outer cylinder body, a hydraulic cylinder, a spring, a switch valve clack and the like. When the safety valve needs to be opened, the hydraulic cylinder is pushed by pressurization to move and open the valve clack of the safety valve, so that underground fluid or an operation tool can be allowed to pass through the safety valve; when the safety valve needs to be closed, the hydraulic cylinder moves reversely under the action of the spring by releasing the pressure in the hydraulic cylinder, and the valve clack of the safety valve can be closed. After the valve clack of the safety valve is closed, the well is closed, and then downhole fluid or other tools cannot pass through the well.
However, due to various reasons such as long-term production and downhole fluid action, the safety valve is damaged, so that the safety valve is damaged or fails, and the valve clack of the safety valve cannot be opened or opened completely or cannot be closed or closed completely.
