Casing and Tubing Coupling API

Casing and TUBING COUPLING API

TUBING and CASING are essential tools in oil production.
Tubing is the pipe that runs the casing of an oil well in the normal course of production. In a flowing well, oil flows through tubing to the surface and into the gathering and transportation process. In a mechanical production well, a combination of tubing, a sucker rod, and a deep well pump, known as a sucker rod. "Three pumping" equipment) will pump oil to the ground, into the gathering and transportation process.
Casing is a pipe that is placed into a well after drilling. CASING COUPLING The casing and well wall are sealed with cement and then perforated with a perforating gun aimed at the target zone, allowing the oil to flow through the rock, cement jacket and casing to the bottom of the well and then through the tubing to the surface.
The main functions are as follows: first, strengthen the shaft wall to prevent the formation collapse; Second, API 5CT COUPLING seal different oil and water layers to realize stratified mining; Third, it is easy to implement fracturing, acidizing and other measures and maintenance operations. Four is the formation of oil flow channel, with the oil pipeline cooperation, oil recovery purpose.
The sequence of operations is as follows: Casing is run after the well is completed, the casing is cemented to the wall, and the tubing is run into the casing. The tubing is equipped with oil packer, pump and other downhole tools. ubing Coupling The sucker rod is placed in the tubing, and the sucker rod pulls the piston of the pump up and down. That way, the oil is pumped underground.

Couplings are used to connect two joints of Tubing Coupling or casing pipe together.

Couplings are short length of heavy wall pipe with the same threads on each end.

EASTSUN manufactures tubing coupling and casing tubing coupling strictly comply with API 5CT latest standard.
