Oil Resistant Petroleum Drilling Oilfield Casing
Oil drilling 7in oil field casing is a steel pipe specially used for the production of oil and gas wells containing carbon dioxide ions, chloride ions and acidic media. It has the characteristics of high strength, high corrosion resistance and high toughness, and can adapt to high temperature and harsh geology environment. This product uses a series of super 13Cr pipes developed by special steel pipes, which not only improves the mechanical properties of the casing, but also enhances the corrosion resistance of the casing to carbon dioxide and hydrogen sulfide. This product conforms to API 5CT standard and can be used for casings of various specifications and connection methods. Compared with ordinary casing, 7in oilfield casing for oil drilling has many advantages: excellent corrosion resistance; it enables oilfield casing to resist corrosion of casing by carbon dioxide, chloride ions and acidic media, prolongs the service life of casing, reduces The cost of repair and replacement. High strength and good toughness; the oil field casing is made of super 13Cr steel, which has high yield strength and tensile strength, and also has good low temperature toughness, which can withstand high temperature and high pressure conditions, preventing casing rupture or out of shape. The bushing has strong adaptability and high reliability. This product can be used for casings of different diameters, lengths and connections, and is suitable for drilling and completion operations of various oil and gas wells, improving the production efficiency and safety of oil and gas wells.

Applications
Oil drilling 7in oil field casing is mainly used for the production of oil and gas wells containing carbon dioxide ions, chloride ions and acidic media, such as: high temperature and high pressure oil and gas wells. This product can maintain stable performance in high temperature and high pressure environment, preventing the casing from being damaged due to temperature or pressure changes.
Sour oil and gas wells. This product can resist the corrosion of the casing by acidic medium, prolong the service life of the casing, and reduce the cost of maintenance and replacement.
Oil and gas wells containing carbon dioxide or hydrogen sulfide. This product can enhance the corrosion resistance of the casing to carbon dioxide or hydrogen sulfide, and prevent the casing from failing due to these harmful gases.
