Oil Screen Strengthening And Toughening Heat Treatment Process

The oil screen is a large-diameter pipe that serves to fix oil and gas wells or wells. The casing is pierced into the wellbore and fixed with cement to prevent the wellbore from collapsing from the rock formation and the wellbore, and to ensure that the drilling mud flows in a loop to facilitate drilling. Different types of casing used in oil excavation: The surface oil screen maintains the well to avoid contamination by shallow water and shallow gas layers, supports wellhead equipment and adheres to other layers of the casing. The skill oil screen separates the pressure at different levels so that the drilling fluid flows normally and maintains the production casing. In order to anti-burst equipment, leak-proof equipment and tail pipe in the drilling equipment. Oil-sand oil screens export oil and gas from the subsurface storage. Used to maintain drilling and stratify the drilling mud. When the oil screen is produced, the outer diameter is generally 114.3 mm to 508 mm.

Domestic economic data showed that the economy was still in the downward direction. First, the world economy is weak, and the increase in exports is more difficult. Second, the cost of domestic labor, capital, financing, etc. is rising and needs to be weakened, and the capital contribution will be affected. Third, the production companies such as raw materials continue to be in the process of destocking. Even the scene of limited production and insured prices will be presented. Fourth, the deep adjustment of the real estate industry in the face of falling prices will affect the industries such as steel, building materials and home appliances. In the context of a general slowdown in the country, the economic growth in the second quarter is expected to continue to slow down.
