Description

Technical Field

[0001] The utility model relates to the technical field of oil field pumping, and in particular to an automatic pressure operation device. Background Art

[0002] Oil is buried in oil and gas layers tens to thousands of meters underground. To extract it, it is necessary to build an oil and gas channel between the ground and the underground oil and gas layers. This channel is the well. Pressurized devices are often used when repairing wells. The working principle of pressurized well repair is to seal the pressure in the pipe string with an internal plug, install the whole set of equipment on the wellhead, and use annular blowout preventers or gate blowout preventers to seal the pressure of the oil pipe and casing annulus. When the upward force of the well pressure on the pipe string is greater than the dead weight of the pipe string, a hydraulic anti-top cava is used to clamp the pipe string, and a lifting cylinder is used to lift and lower the pipe string and downhole tools. When the upward force of the well pressure on the pipe string is less than the dead weight of the pipe string, the winch of the well repair rig is used to lift or lower the pipe string and downhole tools. When the well pressure is high, the single gate blowout preventer and the annular blowout preventer can be used to pour out the coupling. When the well pressure is low, the annular blowout preventer can be used to force through the coupling. When it is necessary to lift and lower a long tool string, a lifting short section can be added to pour out or pour in the tool string.

[0003] Therefore, when using a pressurized device for well repair work, the corresponding equipment needs to be installed at the wellhead and the pressurized device needs to be aligned with the wellhead. However, the existing pressurized device may have position deviation problems after installation. If adjustment is required, it needs to be disassembled and reinstalled, which is very inconvenient and not conducive to use by staff. Utility Model Content
