Description

main feature:
1, automatic irrigation mud designed to reduce the amount of mud on the back of the annulus and the return rate, reduced sleeve decentralization process of the bottom of the shock pressure, effectively prevent casing pressure process because of the excitement caused by lost circulation .
2. For cased during the middle of the establishment of recycling, can be performed at any time, without affecting the float collar float shoe play various functions.
3, automatic irrigation mud casing design by eliminating the need irrigation mud halfway, continuous casing operation can save construction time, to avoid the process of filling the mud casing tubing accident occurred pause.
4, drilling design, you can use ordinary cone bit PDC drill bit or direct drilling, improve construction efficiency.
5, leaf valve and seat soft metal material, after deformation under pressure can produce trace, help to improve the sealing effect, the back pressure seal the bigger the better.
6, tongue control valve closed by the return spring, which controls single-stream time is short, can effectively avoid the water to form a slurry reflux cement plug in the tube.
7, automatic current limiting design, by limiting the amount of mud filling plate is automatically adjusted according to downhole pressure changes, so the bottom to keep the pressure balance and stability.
8, the body of material strength equivalent APIP-110 grade.
