The outer casing is located at the outermost layer, used to seal off the soft and easily collapsed layers in the upper part of the formation, install the wellhead, control the blowout, and support the technical casing and oil layer casing. Usually grade J55 or K55 is widely used, LSAW casing pipe is basically economical than seamless casing pipes for large diameter pipes.
