J55 Oil Casing For Farmland Irrigation

The seamless casing is a large-diameter pipe that functions as a fixed oil and gas well wall or wellbore. The casing is inserted into the wellbore and cemented to prevent the wellbore from separating the rock formation and the wellbore collapse, and to ensure that the drilling mud is circulated for drilling and exploration. Different types of casing used in oil production: Surface oil casing – protects the well from contamination by shallow water and shallow gas layers, – supports the wellhead equipment and maintains the weight of other layers of the casing. Technical oil casing – separates pressures at different levels so that drilling fluid flows properly and protects the production casing. – In order to install anti-explosive devices, leak-proof devices and tail pipes in wells.

Reservoir oil casing – Exports oil and gas from the reservoir below the surface. – It is used to protect the well and stratify the drilling mud. When the oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm. The API oil casing has a hollow cross-section and is used in large quantities as a conduit for fluids, such as oil, natural gas, gas, and water. The use of steel pipes for the manufacture of annular parts can increase the material utilization, simplify the manufacturing process, save material and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing.

Specializing in the production of P110 oil casing, J55 oil casing, K55 oil casing, L80 oil casing, N80 oil casing, geological pipe, water well casing manufacturers are now facing the country to sell all kinds of oil casing, geological tubes, wells Casing. Specializing in the production of gas wells dedicated N80 partial ladder deduction oil casing, factory direct N80 partial ladder deduction oil casing low prices, geothermal wells with partial ladder deduction N80 oil casing, gas well support with partial ladder deduction N80 oil casing widely used In the manufacture of structural parts and mechanical parts, such as oil drilling rods, automotive transmission shafts, bicycle racks, and steel scaffolding used in construction.


The use of petroleum cracking tubes for the manufacture of annular parts can increase the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. Petroleum cracking pipes, like seamless steel pipes, are indispensable materials for various conventional weapons. Barrels, etc., have to be manufactured with petroleum cracking pipes. Petroleum cracking pipes can be classified into round pipes and shaped pipes according to the shape of the cross-sectional area.

Oil casing is a steel pipe that supports oil and gas well walls. Each well requires several layers of casing based on different drilling depths and geology. After the casing is drilled, the cement is used to cement the well. Unlike the tubing and drill pipe, it cannot be reused and is a disposable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes. Casings can be categorized according to usage: ducts, surface casings, technical casings and oil reservoir casings.

The oil casing is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes oil drilling pipes, oil casings, and oil extraction pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing is mainly used to support the wellbore during and after drilling to ensure the normal operation of the entire oil well after the drilling process is completed.

The pumping pipe mainly transports the oil and gas at the bottom of the well to the ground. Oil casing is the lifeline to maintain well operation. Due to different geological conditions, the downhole stress state is complex, and the combined action of pulling, pressing, bending, and torsion stress acts on the pipe body, which imposes higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason, it may result in a reduction of the entire well, or even scrapped.
