    The casing is different from the drill pipe. It is a one-time pipe that is not required to be thickened. The length is not strictly regulated. In order to ensure the cementing quality and smoothly enter the casing, the structural design of the casing string is to be carried out. Cement injection. It is the key process after the casing enters the well
