API Cement Type 9 5/8" Float Collar and Float Shoe for Deep Well Oil Drilling
Float collar applications:
Float collar is installed on the casing and up the float shoe. Like float shoe, it also provide buoyancy to the casing string when it's lowered, reducing the load on the drilling rig. A build-in check valve provides buoyancy to the casing string also prevents cement from re-entering the casing after it's displaced. It's a receptacle to cement plug.
Float collar feature:
1. All inner parts are made of easily drillable aluminum alloy.
2. The device can be connected directly to the casing of the same type.
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. Non-rotating landing plate is available on request.
6. Either PDC or rock bit drillable.
