Problems solved by technology
Since the opening operation needs to be operated at the wellhead of each gas well, and the actual on-site operators are insufficient, especially when a large number of gas wells are operating, firstly, there is a relative lack of personnel, and secondly, the opening time is relatively long, so to a certain extent, it cannot Meet the needs of production

The invention discloses a remote intelligent switch control device of a gas wellhead. The remote intelligent switch control device of the gas wellhead comprises an electric throttle valve, a needle valve intelligent controller, a wellhead switch intelligent controller, an electronic controlled wellhead emergency shutdown valve, a solar power device, an oil jacket pressure transmitter, a tube pressure transmitter, a flowmeter and a valve pressure transmitter. The remote intelligent switch control device of the gas wellhead can effectively solve problems of heavy operation procedures to open and shut a massive gas well when a gas filed is in maintenance or in the process of stopping production, can adjust production systems of intermittent gas wells and control wells with automatic switches. The remote intelligent switch control device of the gas wellhead can not only solve the problem of opening and shutting high-pressure gas wells, but also accelerate delicacy management of stripper wells and inefficient wells; the delicacy management of wellheads of massive and large-scale wells, and management purpose of one well one method and one technology can be achieved definitely.
Description
technical field [0001] The invention relates to a control device, in particular to a remote intelligent switch control device for a natural gas wellhead. Background technique [0002] The medium and low pressure gathering and transportation process modes of natural gas fields are: "downhole throttling, no heating at the wellhead, no alcohol injection, medium and low pressure gas gathering, liquid metering, series connection between wells, remote control, normal temperature separation, two-stage pressurization, centralized treatment ". Mainly through the downhole restrictor, the high-pressure natural gas in the wellbore is throttled and depressurized, and then enters the medium-low pressure gathering and transportation system on the ground through the gas production wellhead. In order to prevent the sudden failure of the downhole restrictor, a high and low pressure emergency cut-off valve is installed at the wellhead to ensure that after the restrictor fails, the high-pressu...
