API 5CT K55 Carbon OCTG Oil Casing Tube

API 5CT K55 Carbon OCTG Oil Casing Tube

The Oil casing is used to support the well bore of oil and gas wells to ensure the normal operation of the whole well after drilling and completion. Each well should use several layers of casing according to different drilling depth and geological conditions. Cement cementing is used after casing goes down. It is different from tubing and drill pipe. It can not be reused. It belongs to disposable consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well tubes. Casing can be divided into: conduit, surface casing, technical casing and reservoir casing.

Oil casing is the lifeline for maintaining oil well operations. Due to different geological conditions, the state of the downhole is complicated, and the combined action of tension, compression, bending and torsion stress acts on the pipe body, which puts high requirements on the quality of the casing itself. Once the casing itself is damaged for some reason, it may result in a reduction in production and even scrapping of the entire well.
