An intelligent handwheel device for remote switching of wellhead valves

Abstract

The invention provides an intelligent handwheel device for remote switching of wellhead valves, which belongs to the field of control valves, and includes a clutch mechanism, a valve handwheel, an intelligent valve casing, and an intelligent valve inner casing arranged inside the intelligent valve casing. The sleeve cooperates with the valve body, and the valve handwheel is sleeved on the smart valve outer sleeve; the disconnection or connection of the smart valve outer sleeve and the smart valve inner sleeve is controlled by the clutch mechanism. This device can make the control center know the switch state of each valve at all times and authorize the staff to control the valve, so as to solve the problem of oil and gas anti-theft, so that the central control room of each oil (gas) production area can control the opening or closing of each well station in real time Valves, the opening and closing status of the valves of each well station and whether the valves are damaged can be checked in real time on the system, which fundamentally solves the problem of valve monitoring by the oil and gas stealing management agency.

Description

technical field [0001] The invention belongs to the field of control valves, in particular to an intelligent handwheel device for remote switching of wellhead valves. Background technique [0002] At present, most of the oil and gas resources in China are distributed sporadically in a wide area except for a few large oil fields and gas fields, and the reserves are very uneven. As a result, oil (gas production) enterprises will be located in a large area. A large number of well stations have been deployed, and a considerable part of them have been set as unmanned well stations due to reasons such as production and geographical location. The unmanned well station is usually unattended, only surrounded by walls, and the valve cannot be locked or the locking method cannot fundamentally solve the problem that it cannot be sensed when it is stolen, which often leads to nearby villagers or professional oil stealers ( Gas) gangs invade unmanned well stations to steal oil (gas), and...

AI Technical Summary

Problems solved by technology

However, the intelligent valve control system used in power plants requires the use of unique electronically controlled valves and switches driven by compressed air, which is difficult to implement for unmanned wells

First of all, the valves used in unmanned wells are all manual valves. It will cost a lot of money to replace the electronically controlled valves, and there may even be risks such as blowouts when replacing the valves, which greatly increases the difficulty and cost of replacement; Secondly, a considerable number of unmanned wells are not covered by the power grid, so they cannot use pure electric drive to open the valve, let alone use compressed air to drive the opening and closing valve.
