The Importance Of Oil Casing
2021-11-18 11:09:15

Petroleum casing is a large-diameter pipe that plays a role in fixing the walls or boreholes of oil and gas oil wells. The casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating the rock formation and the wellbore from collapsing, and to ensure the circulation of the drilling mud to facilitate drilling and production.

Steel grade of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Form of casing end processing: short round thread, long round thread, partial trapezoidal thread, special buckle, etc. Used for oil well drilling is mainly used to support the well wall during drilling and after completion, to ensure the drilling process and the normal operation of the entire oil well after completion. Let's introduce the important position of petroleum casing.

The importance of oil casing

The petroleum industry is an industry that uses a large number of petroleum casing pipes, and the petroleum casing plays an important role in the petroleum industry:

1 The large amount of oil casing and the high cost of the oil casing have the potential to save expenses and reduce costs. The consumption of oil well pipes can be calculated by the annual drilling ruler. According to China's specific conditions, roughly 62 kg of oil well tubing is required for each 1 m of drilling, of which 48 kg of casing and 10 kg of tubing. 3kg drill pipe, 0.5kg drill collar;

2 The mechanical and environmental behavior of the oil casing has an important impact on the use of advanced processes and production and efficiency in the petroleum industry;

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