The use of oil casing

Update:2022-08-11   View(s):196   Keywords :The use of oil casing
An oil casing is a large-diameter pipe that acts to fix the wall or bore of oil and gas oil wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock formations and prevent the wellbore from collapsing while ensuring the circulation of drilling mud to facilitate drilling and mining.

Steel grade of petroleum casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. The processing form of the casing end: short round thread, long round thread, buttress thread, special buckle, etc. Used in oil well drilling, it is mainly used to support the well wall during the drilling process and after the completion of the well, so as to ensure the drilling process and the normal operation of the entire oil well after the completion of the well.

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

1. Oil pipelines use a large amount of money and spend a lot of money, and have great potential to save expenses and reduce costs. The consumption of OCTG can be calculated according to the number of drilling feet per year. According to the specific situation of our country, in general, 62kg of oil well pipe is required for every 1m of drilling, including 48kg of the casing and 10kg of oil pipe. Drill pipe 3kg, drill collar 0.5kg;
2. The mechanics and environmental behavior of oil pipes have an important impact on the adoption of advanced technology and production and efficiency in the oil industry;
3. The failure loss of oil pipes is huge, and its safety, reliability, and service life are of great importance to the oil industry.
