Our many years and a lot of cash inventory can be shipped the same day, please come to order. oil casing itself by the strength of the steel casing can be divided into different grade, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150 and so on. Well conditions, depth of different steel grades used are different. In a corrosive environment also requires the casing itself has corrosion resistance. In complex geological conditions where the sleeve has also asked the collapsing performance. Oil Casing is a large-diameter pipe, played the role of fixed oil and gas wells, or wellbore wall. Cannula is inserted into the wellbore, the fixed with cement to prevent the borehole spaced formation and borehole collapse and to ensure drilling mud circulation to facilitate drilling mining. Different types of casing used in oil extraction process: Surface oil casing - protection drilling to avoid the contamination of shallow aquifers and shallow gas - supporting wellhead equipment and other layers to maintain the casing weight. Technical Oil Barrel - separate the different levels of pressure, in order to limit the normal flow of drilling fluid and protect the production casing. - In order to install anti-burst device, leak-proof devices and tailpipes in the drilling. Oil casing oil - exporting oil and gas from under the surface in the storage layer. - For the protection of drilling, the drilling mud layers. When the oil casing production, typically 114.3 mm outer diameter to 508 mm. API oil casing having a hollow cross section, a large number of used pipes conveying fluids, such as transportation of oil, gas, gas, and water. With a steel pipe manufacturing ring parts Can improve material utilization, simplify the manufacturing process, saving materials and processing time, such as bearing rings, jack sets, it has been widely used to manufacture steel. API oil casing is mainly used to transport oil and gas well drilling and oil and gas. It includes oil drill pipe, casing, tubing pumping. Oil drill pipe used to connect the drill collar and drill bit and drilling power transfer. Oil casing is mainly used to support the rear of the wall during drilling and completion, and after completion to ensure the normal operation of the entire drilling process wells. Oil well casing is run to maintain a lifeline. Due to different geological conditions, underground complex stress state, pulling, pressing, bending, torsional stress acting on the combined effect of the tube, which is the quality of the casing itself made a higher demand. Once the casing itself is damaged for some reason, it could lead to the whole production wells, or even scrapped.
