API Oilfield Seamless Tubing and Casing Pup Joint

API 5CT L80 N80 J55 K55 P110 Oilfield Seamless TUBING and Casing PUP JOINT

Tubing and CASING are essential tools in oil exploitation
The main functions are as follows: first, reinforce the shaft wall to prevent formation collapse; Second, seal off different oil layers and water layers to realize layered mining; Third, it is easy to implement fracturing, acidizing and other measures and maintenance operations. The fourth is to form the oil flow channel and cooperate with the tubing to achieve the purpose of oil production.
The operation sequence is: after the oil well is drilled, run the casing, seal the casing with the well wall with cement, and run the tubing in the casing. The oil pipe is equipped with downhole tools such as oil seal separator and pump. The sucker rod is lowered into the oil pipe and pulls the piston of the pump up and down. In this way, oil will be pumped to the surface.

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
