Important position of oil pipe

Oil pipe is a kind of steel pipe used to support the wall of oil and gas wells to ensure the normal operation of the whole oil well after drilling and completion. According to different drilling depth and geological conditions, each well should use several layers of casing. Cement cementing should be used after oil pipe running down well. It is different from tubing and oil pipe and can not be reused. It is a disposable consumable material. Therefore, the oil pipe consumption accounts for more than 70% of the total oil pipe.

　　Petroleum industry is a large number of industries that use oil pipe. Oil pipe play an important role in the petroleum industry.

　　1, the huge volume of API 5L X70 LSAW Carbon Steel Oil Pipe, the cost of money, the cost savings and the potential to reduce costs are enormous. The consumption of oil pipes can be calculated according to the annual drilling scale. According to the specific conditions in China, 62 kg of tubing is needed for every 1 m of drilling, including 48 kg of casing and 10 kg of tubing. Drill pipe 3kg, drill collar 0.5kg;

　　2. The mechanical and environmental behavior of oil pipe has an important influence on adopting advanced technology and increasing production efficiency in petroleum industry.

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