API spec 5ct N80-1 Casing Tube
Special oil pipe is mainly used for oil, gas well drilling and oil and gas transportation. It includes oil drilling pipe, oil casing, pumping pipe. Oil drill pipe is mainly used to connect drill collar and drill bit and transfer drilling power. Oil casing is mainly used to support the wellbore during drilling and after completion. Due to the different geological conditions, the downhole stress state is complex, and the tension, compression, bending and torsion stress act on the pipe body comprehensively. The quality of casing itself is required to be high. Once the casing itself is damaged for some reason, it may lead to the reduction of production or even the abandonment of the whole well. N80-1 casing price to ensure that the drilling process and The normal operation of the whole well after completion. The tubing mainly carries oil and gas from the bottom of the well to the ground.
The oil casing is the lifeline to maintain the operation of oil well. According to the strength of steel, the casing can be divided into different steel grades, namely, J55-K55-N80N80C90 T95N P110Q125V 150 and so on.
Well conditions, well depth, the use of different steel grades. The casing itself is also required to have corrosion resistance in corrosive environment. Where geological conditions are complicated, casing is also required to be collapsing resistant.
Surface oil casing-protects drilling from contamination by shallow water and gas formations, supports wellhead equipment and maintains casing weight in other layers. Technical oil casing-separates different layers of pressure so that drilling fluid flows normally and protects production casing.-for installation of backburst devices, leak preventer and tailpipe in drilling. Reservoir casing-Extracts oil and gas from the underlying reservoir.-used to protect drilling and stratify drilling mud.
The outer diameter of the casing is usually 114.3 mm to 508mm. The API casing has a hollow section. The Chaoyang N80-1 casing is widely used as a conduit for conveying fluid, such as oil, natural gas, water, etc. Using steel tube to manufacture annular parts can improve material utilization, simplify manufacturing process, save material and working time, such as rolling bearing ring, Jack sleeve, etc. At present, it has been widely used in steel pipe manufacture.
