API Petroleum Casing Stubs Product Description

Petroleum casing is a large diameter tubing that serves to secure the wall or borehole of oil and gas wells. The casing is inserted into the borehole and secured with cement to prevent the borehole from separating the rock formation and collapsing, and to ensure the circulation of drilling mud to facilitate drilling and extraction.
Steel grade of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Casing end processing forms: short round thread, long round thread, partial 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 entire well after the completion of the well.
The important position of oil pipe
The petroleum industry is an industry that uses a large amount of petroleum tubing, and petroleum tubing plays an important role in the petroleum industry.
1 Oil tubing use is large, spend a lot of money, saving money and reducing the cost potential is huge. The consumption of oil well pipe can be projected by the annual drilling footage. According to the specific situation in China, roughly 62kg of oil tubing is needed for every 1m drilled, including 48kg of casing, 10kg of tubing. 3kg of drill pipe and 0.5kg of drill collar.
2 The mechanical and environmental behavior of oil tubing has an important impact on the adoption of advanced processes and increased production and efficiency in the oil industry.
3 Petroleum pipe failure loss is huge, starting from safety and reliability and oil life is of great importance to the oil industry.
