Float Collar and Float Shoe

Float equipment serves as the backbone of casing equipment used during primary cementing operations.Float equipment guides the casing to total depth and prevents contaminated mud from entering the casing.Also,it provides a landing point for casing wiper plugs,reinforces the lower end of the casing string,and ensures greater accuracy of cement slurry displacement.

The top of the floating shoe has a guiding function;  

 The filling material of the floating float hoop shoe is high-strength G-grade cement, which has good drillability while ensuring the sealing property;

The valve body material is high-strength aluminum alloy , with good erosion resistance and anti-back pressure capability; 

Available in single and double valves.

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 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.
