API Oilfield Cementing Tools Float Shoe Float Collar Casing Guiding Shoe
Float Collar & Float Shoe Description of Oilfield Cementing Tools:
The cement float collar& shoe offer dependable performance for all classes of oil and gas wells. The plunger type valves prevent cement backflow, provide casing buoyancy during run-in, and act as internal bops during the process of running and cementing the casing. Our float collar & shoe sizes range from 5 1/2" – 30" with float ball, stab in, non-rotating, spring and single / double valve types. Products in our factory are all manufactured to API standard, with strict quality control and inspection.
Float collar is a component installed near the bottom of the casing string on
which cement plugs land during the primary cementing operation. It
contains a check valve to permit fluid to pass downward but not
upward through the casing. The float collar prevents drilling mud
from entering the casing while it is being lowered, allowing the
casing to float during its descent and thus decreasing the load on
the or mast.
Float shoe is 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.
