Liuzhou Steel Pipe Co., Ltd. Cangzhou (Manager Wu: 18333440848 QQ: 3024587634) is a professional K55 oil casing manufacturers, headquartered in China, Hebei Enzan pipeline base, I plant the K55 oil casing, K55 outside the thick oil pipeline complete K55 long round buckle oil casing, K55 short round buckle oil casing, K55 partial ladder buckle oil casing, N80 petroleum casing, L80 oil casing, P110 casing, J55 oil casing wells special specifications such as Wumart inexpensive, sincerely look forward to your visit. company sells high-N80 petroleum casing, P110 oil casing, J55 oil casing, K55 oil casing, L80 oil casing, api oil casing and other metal materials. Oil Casing is a large-diameter pipe, played the role of fixed oil and gas wells, or wellbore wall. Cannula is inserted into the wellbore, the fixed with cement to prevent the borehole spaced formation and borehole collapse and to ensure drilling mud circulation to facilitate drilling mining. (Surface casing) The company produces surface casing, surface casing is a large-diameter pipe, played the role of fixed oil and gas wells, or wellbore wall. Cannula is inserted into the wellbore, the fixed with cement to prevent the borehole spaced formation and borehole collapse and to ensure drilling mud circulation to facilitate drilling mining. Different types of casing used in oil extraction process: Surface oil casing - protection drilling to avoid the contamination of shallow aquifers and shallow gas - supporting wellhead equipment and other layers to maintain the casing weight. Technical Oil Barrel - separate the different levels of pressure, in order to limit the normal flow of drilling fluid and protect the production casing. - In order to install anti-burst device, leak-proof devices and tailpipes in the drilling. Oil casing oil - exporting oil and gas from under the surface in the storage layer. - For the protection of drilling, the drilling mud layered H40.J-55, K-55, N-80, L-80, C-90, C-95, P-110, Q-125 and the like. API5CT buckle type oil casing has STC (short round buckle), LTC (long round buckle), BTC (partial ladder buckle), VAM (tortoise buckle) and other button type. API5CT oil casing length R1, R2, R3. API5CT oil casing standard length of three: the R-1 is 4.88 ~ 7.62m, R-2 is 7.62 ~ 10.36m, R-3 is 10.36m to be longer. 1 large oil works, do more, great savings, cost reduction potential. According to the annual consumption of oil well pipe drilling foot volume projections. According to China's specific conditions, generally did not require drilling 1m OCTG 62kg, wherein the casing 48kg, tubing 10kg. Drill 3kg, drill collar 0.5kg. Mechanical and Environmental Behavior 2 oil pipe to the oil industry with advanced technology and production efficiency has an important impact. 3 oil pipe failure huge losses, from the safety and reliability of the oil industry and oil life at stake
