The Important Role Of Oil Casing
2021-11-18 10:40:57

Oil casing is a large-diameter pipe that can fix oil and natural gas oil well walls or well holes. The casing is pierced into the borehole and fixed with cement to help the borehole separate the rock formations and prevent the borehole from collapsing, while ensuring the circulation of drilling mud to facilitate drilling and exploitation.

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

The petroleum industry is widely used in the petroleum pipe industry and occupies a very important position in the petroleum industry:

1. There is a large amount of oil casing and a lot of money, which has huge potential to save expenses and reduce related costs. The consumption of oil well pipes can be calculated based on the annual drilling scale. According to my country's detailed situation, roughly 62kg of oil well pipes are required for every 1m drilled, including 48kg of casing and 10kg of tubing. Drill pipe 3kg, drill collar 0.5kg;

2. The mechanics and environmental behavior of petroleum pipes have an important impact on the adoption of advanced technology and the increase in production and efficiency in the petroleum industry;

3. The loss of oil pipe failure is huge, and its safety, reliability and lifespan of conventional use are seriously related to the oil industry.
