Float collar and float shoe is one of the conventional and necessary accessories of lower casing string structure, usually connecting at the bottom of the tubing string, used to guide the casing string smoothly into the hole, playing a suspended casing, preventing the cement slurry reverse flow and realization of condensation after cementing bump pressure discharge pressure, reducing derrick load, controlling the height of cement plug.

2. Features:

1) All inner parts are made of easily drillable aluminum alloy

2) The device can be connected directly to same type casing

3) Reliable back-pressure leak proof structure, enable grout or slurry flow with less resistance

4) Valve seat and valve disk can effectively prevent grout from flowing back

5) Hardness of base material is equivalent to API Spec N-80
