High pressure gas well wellhead sealing simulation device

Abstract

A high-pressure gas well wellhead sealing simulation device. It includes a power system, a feedback control unit and a gas leak detection unit. The power system includes a motor, a crankshaft connecting rod mechanism, a simulated pipe string and a blowout preventer rubber cartridge; the gas leak detection unit includes a gas storage tank, a supercharger, A gas detection sensor and an alarm; the feedback control unit includes a gas detection sensor, a controller for controlling the loading of a hydraulic pump, and a hydraulic pump for providing a loading for the blowout preventer. The device can not only simulate the wellhead sealing of high-pressure gas wells, but also provide early warning for gas leakage, and realize adaptive adjustment after gas leakage through detection and feedback. experimental research in the case.

Description

technical field

[0001] The invention relates to a gas well wellhead blowout prevention sealing test device, in particular to a high pressure gas well wellhead blowout prevention sealing test device. Background technique

[0002] With the strategic transfer of energy from traditional oil and water wells to natural gas, shale gas, and coalbed methane wells in various countries in the world, the number of oil and gas wells in the country has soared year by year, and the issue of pressure sealing of gas well annular blowout prevention rubber cores has attracted more and more attention. However, the current gas well annular blowout preventer does not have a reliable early warning system, and lacks a sealing adaptive adjustment system with pressure feedback function in the working process. In order to solve this technical problem, domestic researchers need a device that can simulate the operation state of the blowout preventer in the high-pressure gas well in the laboratory, and c...
