Detailed introduction of oil casing manufacturer for oilfield

Oil casing is the lifeline to maintain the operation of oil wells. Due to different geological conditions, the state of downhole stress is complex, and the combined effects of tensile, compressive, bending and torsional stresses act as Zhixin Group for the pipe body, which puts high demands on the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to the reduction of production of the whole well, or even scrapped. According to the strength of the steel itself casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different well conditions and depths require different steel grades. In corrosive environments, the casing itself is required to have corrosion resistance. In complex geological conditions, the casing is also required to have resistance to extrusion and destruction.

  Since December last year, the whole country has been whipping up a storm of “ground steel” rectification. The company’s main goal is to provide the best possible service to its customers. Recently, the Development and Reform Commission of Hebei Province issued a “capacity replacement ratio of less than 1.1.25 has been recorded steel smelting projects immediately stop building rectification notice”, requiring the relevant project units in the receipt of this document to improve the relevant approval procedures, the completed project shall not be put into operation, has started the project to be in a state of suspension, not started the project shall not start construction, violators according to illegal construction of steel smelting projects seriously investigated and punished. The Ministry of Economic Development and Trade of Ukraine issued a report on the same day, the Egyptian Ministry of Trade and Industry launched an anti-dumping investigation against steel bars originating from China, Turkey and Ukraine. Rebar futures pulled up again, but the downstream users’ purchasing power was not strong, and intermediaries lost their “fighting spirit”, and the market did not warm up in parallel. The company’s selling price was also adjusted back by 20 yuan/ton in the morning.

When drilling to the destination layer (layers containing oil and gas), the oil layer casing is needed to seal all the oil and gas layers and the upper exposed strata, and inside the oil layer casing is the oil layer. The oil layer casing is the deepest among all kinds of casing, and its mechanical properties and sealing performance requirements are also the highest, using steel grades such as K55, N80, P110, Q125 and V150. The main specifications of oil formation casing are: 177.8mm(7in), 168.28mm(6-5/8in), 139.7mm(5-1/2in), 127mm(5in), 114.3mm(4-1/2in), etc.
