Float collar Float shoe Float collar Float shoe are mounted on the middle and end parts of casing string, the main purpose is to prevent the annulus grout pour back into the pipe string, the check valve can provided buoyancy and alleviate the drilling rig loading in the process of putting the casing pipe.
After cementing slurry displacement, float collar can also withstand cementing plug and achieve bumping.
