Float Collar&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. Float Collar &shoe Inner Structure Float Collar&Shoe Production and Inspection
Float collars are placed one to three joints above the guide shoe
or float shoe. They 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
backpressure valve and serve basically the same function as the float
shoe.
