Uses of oil casing

Oil casing is a large-diameter pipe that serves to fix the wall or borehole of oil and gas wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock layer and prevent the wellbore from collapsing while ensuring the circulation of drilling mud for drilling and mining.

Steel grade of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Casing end processing form: short round thread, long round thread, trapezoidal thread, special buckle, etc. It is mainly used for oil well drilling to support the well wall during the drilling process and after the completion of the well, to ensure the normal operation of the drilling process and the entire oil well after the completion of the well.

The oil industry is an industry that uses a large number of oil pipings, and oil pipings occupy a very important position in the oil industry:

1. Oil pipings are used in large quantities and cost a lot, and there is great potential for saving expenses and reducing costs. The consumption of oil well pipe can be calculated based on the annual drilling measurement. According to the specific situation in my country, generally, 62kg of oil well pipe is needed for every 1m of drilling, including 48kg of casing and 10kg of oil piping. The drill pipe is 3kg and the drill collar is 0.5kg;

2. The mechanical and environmental behavior of oil piping has an important impact on the adoption of advanced technology and the increase of production and efficiency in the oil industry;

3. The failure loss of oil piping is huge, and its safety, reliability, and service life are of great importance to the oil industry.
