Seamless L80 TUBING in API 5ct steel pipe

Role of Tubing
① Extraction of oil and gas: after drilling and cementing of oil and gas wells, oil pipes are placed in the oil layer Casing to extract oil and gas to the ground.
② Water injection: When the downhole pressure is not enough, inject water into the well through the tubing.
③ Steam injection: In the process of heavy oil thermal recovery, heat insulation tubing shall be used to input steam into the well.
④ Acidizing and fracturing: in the late period of well drilling or in order to improve the production of oil and gas wells, the acidizing and fracturing media or solids need to be input into the oil and gas reservoirs. The media and solids are transported through oil pipes

CASING is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place
