Application
Casing pipe is widely used for fastening oil and gas well wall or borehold, with bigger diameter than tubing, including surface casings, technical casings and oil layer casings.
Api oil casing pipe, used oil well casing pipe, oil casing price
Oil casing is used to support the oil and gas pipe well, in order to ensure the drilling
Process and after completion normal operation of the wells. Each well depending on the depth of drilling and geological conditions, to use several layers of casing. After
Cementing casing go down to use it and tubing, drill pipe is different, can not be reused, are disposable consumable materials. Therefore, the casing consumption of more than 70% of all the oil well pipe. Casing according to usage can be divided into: a catheter, surface casing, casing and production casing;
Oil casing is a large-diameter pipe, played the role of fixed oil and gas wells,
Or wellbore wall.
Oil casing steel grade: h40, j55, k55, n80, l80, c90, t95, p110, q125, v150 and so
On. End of the tube processing forms: short round thread, long round thread, buttress
Thread, special deduction. Mainly used for oil well drilling support on the wall after
Drilling and completion, and after completion to ensure the normal operation of the
Entire drilling process wells
