Precautions for using Float casing collar:
During the casing running process, the one-way flow of the drilling fluid in the annular space can be realized, the backflow of the cement slurry can be prevented during the cement injection process, and the pressure release and waiting for solidification after the cement bumping can be realized, which is helpful to improve the bonding quality of the cement sheath and the casing; Float casing The collar manufacturer tells you that at the same time, drilling fluid is poured into the casing string to adjust its buoyancy, so that the suspended weight of the casing meets the design requirements for casing running operations.
When using the float casing collar, it is necessary to control the running speed of the casing string to prevent the pressure surge caused by the fast running down, which may cause seal failure or crush the fragile formation. By injecting drilling fluid into the casing and adjusting the hydrostatic column pressure difference inside and outside the casing, the casing can be effectively prevented from being crushed.
