Abstract

The invention relates to the technical field of natural gas remote regulation and control, in particular to a device and method for remote regulation and control of petroleum and natural gas wellhead yield. The device comprises remote terminal equipment and a PLC control unit which is in communication with the the remote terminal equipment. The device is characterized by further comprising an electric actuating mechanism which is in electric connection with the PLC control unit, a throttle valve connected with the electric actuating mechanism and a data acquisition unit and a data processor which are arranged between the throttle valve and the PLC control unit; a fixing seat is arranged on the upper portion of the throttle valve, the electric actuating mechanism is fixedly connected to the upper end face of the fixing seat, a through hole is formed in the middle of the fixing seat in the vertical direction, a connecting shaft penetrates through the through hole, the upper portion of the connecting shaft is connected with the electric actuating mechanism, and the lower portion of the connecting shaft is connected with a valve rod of the throttle valve. By mean of the device and method for the remote regulation and control of the petroleum and natural gas wellhead yield, remote safe regulation and control of the natural gas yield of a well with high pressure and high production ratecan be achieved, and therefore gas well unattended operation can be achieved.

Description

technical field [0001] The invention relates to the technical field of remote control of natural gas, in particular to a device suitable for remote control of output of high-pressure natural gas wells and a method for remote control using the device. Background technique [0002] Shale gas is an unconventional natural gas that occurs in organic-rich mud shale and its interlayers, mainly in the form of adsorption and free, and its main composition is methane. " belong to the same category. The formation and enrichment of shale gas has its own unique characteristics, and it is often distributed in thick and widely distributed shale source rock formations in the basin. Shale gas has been recognized by people for a long time, but it is more difficult to collect than traditional natural gas. With the increasingly scarce resources and energy, as a beneficial supplement to traditional natural gas, people gradually realize the importance of shale gas. [0003] Fuling shale gas dev...
