Abstract

The invention discloses a wellhead sealing simulation device for a high-pressure gas well. The wellhead sealing simulation device for the high-pressure gas well comprises a power system, a feedback control unit and a gas leakage detection unit, wherein the power system comprises a motor, a crankshaft connecting rod mechanism, a simulation tubular column and a blowout preventer rubber tube; the gas leakage detection unit comprises a gas storage tank, a supercharger, a gas detection sensor and an alarm; and the feedback control unit comprises a gas detection sensor, a controller for controlling the loading of a hydraulic pump and the hydraulic pump for providing a load for the blowout preventer. The device can realize simulation of wellhead sealing of the high-pressure gas well, can also perform early warning on gas leakage, realizes self-adaptive adjustment after gas leakage through detection and feedback, and meanwhile, can perform experimental research on sealing performance and frictional wear characteristics of the rubber tube under complex working conditions.

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...
