Casing cementing equipment- float shoe

2026-05-08
Latest company news about Casing cementing equipment- float shoe

The float shoe has a check valve to keep fluids from entering the casing from the bottom. The primary purpose is to hold the cement column in place in the annulus since the density of the cement is usually greater than that of the mud and it would tend to equalize the hydrostatic pressure difference by flowing back into the casing were it not for the check valve.

 

Three types of check valves used in float shoe:

 

1. A ball-type check valve using a low-density ball that floats in the drilling mud or cement.

2. A spring-actuated flapper type check valve.

3. A spring-actuated poppet type valve.
