THE USE OF OIL CASING

Zhongtang Iron And Steel (shandong) Group Co., Ltd. production and sales of tubing pipe, tubing pipe, casing pipe, Sucker Rod and other oil pipe components,

Oil casing is a kind of large diameter pipe, which plays the role of fixing oil and gas well walls or holes. The casing is inserted into the hole and cemented in place to prevent the hole from separating rock and collapsing, and to ensure the circulation of mud for ease and extraction. Oil casing is the steel pipe supporting the wall of oil and gas well, and ensures the normal operation of the whole well. Depending on the depth and geology, several layers of casing are used in each well. Casing well should be cemented. Unlike tubing and drill pipe, it cannot be reused. It’s a disposable consumer material. Therefore, casing consumption accounts for more than 70% of the total consumption of oil tubing.

The transportation of oil or natural gas and oil or natural gas. It includes oil drill pipe, oil casing, pumping unit pipe. The oil drill pipe connects the drill collar to the drill bit and transmits power. Oil casing and wall support to ensure the normal operation of the whole well. Suction tubing carries oil and gas from the bottom of a well to the surface.

Oil casing is the lifeline of oil well operation. Due to the different geological conditions, the underground stress state is complicated, and the comprehensive action of the tensile, compressive, bending and torsional stress of the pipe body puts forward higher requirements for the quality of the casing itself. If the casing itself is damaged for any reason, it can result in reduced production or even abandonment of the entire well.

The casing can be divided into different steel grades according to the strength of the steel itself, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Oil casing steel grade :H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Casing end processing forms: short round thread, long round thread, trapezoid thread, special buckle, etc. And the wall support to ensure the normal operation of the entire well after the end.
