Oil casing is a crucial and fundamental piece of equipment in oil and gas drilling. Its functions include reinforcing the wellbore, isolating different strata, controlling downhole pressure, ensuring smooth drilling, and providing a channel for subsequent oil and gas production.

The main functions of oil casing:
Drilling involves passing through various unstable rock formations, such as unconsolidated sandstone and shale. Casing supports the wellbore wall and prevents collapse and blockage.
It isolates oil, gas, and water layers of varying pressure, preventing them from intermixing and potentially causing accidents. This prevents water from entering the producing zone or air from high-pressure zones from influxing into the wellbore.
It works with equipment such as blowout preventers to form a closed system, acting as a critical barrier to control downhole pressure and prevent blowouts.
It provides a pathway for drill pipe, production tubing (tubing), and downhole tools, and serves as the essential path for oil and gas flows to the surface.
It isolates shallow freshwater aquifers, preventing contamination by drilling fluid and formation fluids.
Oil casing is the lifeline of oil well operation. Due to different geological conditions, the underground stress state is complex, tensile, compressive, bending and torsional stress act on the pipe body. The method of rapid cooling after tempering is adopted to avoid high temperature brittleness and obtain toughness. Second, the subtemperature quenching method through the incomplete austenitizing of steel grades to effectively improve harmful elements and impurities, improve toughness. Casing is inserted into the well hole and secured with cement to help separate the rock formation and prevent the hole from collapsing, while keeping the drilling mud circulating to facilitate drilling and production.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
