Float collars are placed one to three joints above the guide shoe or float shoe.
Float collar provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement. The space between the float shoe and the float collar provides a containment area to entrap the likely-contaminated fluids from the wiping action of the top cementing plug, securing the contaminated fluid away from the shoe where a strong cement bond is of primary importance. Float collars include a back pressure valve and serve basically the same function as the float shoe.
Float shoes contain a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing.

Applications:In all applications ranging from close tolerance liners to full casing strings.
Casing float collar is mainly composed of spoiler, floating ball, the shell and the basket four parts. Casing float shoe is mainly composed of the spoilers, float,housing, guide shoe and basket five parts:spoiler center hole and float with the cone, can reverse the sealing fluid; then basket for supporting the float, circulating wash well.
Adjust the drilling fluid properties, cementing job, the casket supporting float, float collar in the conduction state, the fluid can freely pass:After the injection casing and cementing operations,float collar reverse pressure, float and spoiler with sealing surface can prevent fliud backflow, play reverse seal.
