The whole drilling process no longer uses drill pipe, drill collar, etc. The drill bit is lifted and lowered inside the casing by using wire rope casting, which means that the drill bit drilling tools can be replaced without lifting the drill, reducing the accidents such as starting and lowering the drill and well blowout and stuck drilling, improving the reliability of drilling and reducing the cost.<\/p>","protected":false},"excerpt":{"rendered":"

Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure that the drilling process is carried out and that the entire well operates normally after completion. Several layers of casing are used in each well according to different drilling depths and geological conditions.
