Well control BOP switch valve remote control device suitable for drilling well sites

Abstract

A well-control blowout preventer switch valve remote control device suitable for a well drilling field comprises a ZigBee data transmission module, well-control blowout preventer switch valve slaves corresponding to different positions and a second ZigBee data transmission module connected with the well-control blowout preventer switch valve slaves, wherein each well-control blowout preventer switch valve slave comprises a master controller, an electromagnetic valve module and a switch valve state detection module. External force is not needed, a gas source is stably controlled according to the route position of a switch valve handle, switching on and switching off of a gas inlet hole and gas outlet hole controller are switched, and it is effectively and reliably guaranteed that a well-control blowout preventer switch valve arrives at a set position; in addition, state information of the switch valve can be sent to a computer display interface of a driller operation control platform in real time by means of the user-friendly design, accurate remote control over the well-control blowout preventer switch valve is achieved, and the well-control blowout preventer switch valve remote control device is simple in structure and more intelligent.

Description

Technical field [0001] The invention relates to the technical field of drilling valve control, in particular to a remote control device for a well control blowout preventer switch valve that can wirelessly transmit signals and is suitable for drilling well sites. Background technique [0002] A blowout accident is a very harmful drilling accident due to the huge pressure and shock waves generated during the eruption, which can cause casualties and property losses. Once it occurs, it often produces serious consequences and strict preventive measures must be taken. When a well kick occurs, it is necessary to quickly and accurately shut down the main well, control the wellhead, and prevent blowout accidents. At present, when a blowout accident occurs at the drilling well site, the only way to transmit various shut-in information is to rely solely on the gestures of on-site technicians. When the surrounding environment affects the line of sight, it is easy for the executives to fail ...

AI Technical Summary

Problems solved by technology

[0003] In view of this, the object of the present invention is to propose a remote control device for the on-off valve of the well control blowout preventer suitable for the drilling well site, so as to solve the problem that in the event of a blowout accident, all kinds of shut-in information can only be transmitted by gestures of the field technicians. , and when the surrounding environment affects the line of sight, it will cause misjudgment by the executive personnel, resulting in incomplete shut-in, lagging, sluggish, or even failure of shut-in
