Drill String Float Valve - Flap Type Float Valve

The drill string float valve (flap type) is a key internal blowout prevention device used in drilling operations to prevent well kick and blowout. It is usually installed at the bottom end of the drill string (near the drill bit). Its core function is to maintain fluid pressure balance inside the drill string during drilling. When the drilling fluid circulates normally, the float valve is open to allow fluid flow; when abnormal downhole pressure occurs (such as a well kick), the float valve flap quickly closes to prevent high-pressure fluid from flowing upward.

Detailed Information

The drill string float valve (flap type) is a key internal blowout prevention device used in drilling engineering to prevent well kick and blowout. It is usually installed at the bottom end of the drill string (near the drill bit). Its core function is to maintain fluid pressure balance inside the drill string during drilling. When the drilling fluid circulates normally, the float valve is open to allow fluid flow; when abnormal downhole pressure occurs (such as a well kick), the float valve cover plate quickly closes to prevent high-pressure fluid from rising.

Pin shaft drives roller square patch core

The square core bushing is one of the essential pieces of equipment for petroleum drilling operations. It is placed inside the large square core bushing, and its function is to transmit the torque from the rotary table to the downhole drilling tools.

Connected by Ren cycle joint

The swivel joint is a special joint used to connect the drill pipe with the casing during the middle or after the casing is run, allowing circulation of drilling fluid. It can be divided into drill pipe threaded swivel joints, casing threaded swivel joints, and swivel threaded swivel joints as needed. The upper part of the casing swivel joint has drill pipe joint threads for connecting to the drill pipe or is connected to the pipeline by a swivel joint. The lower part is machined with API casing tapered trapezoidal threads (or API casing long round thread/short round thread) for connecting the casing coupling.
