OCTG Casing and Tubing are essential tubulars.

OCTG Casing and Tubing are essential tubulars.
Production tubing is normal nowadays into the well casing pipe in the well. Flowing wells, oil flows into the ground through the tubing into the gathering process. Apheresis wells, tubing, sucker rod deep well pump (ie, "three pumping" device) combination, the oil pumped to the surface, into the gathering process.
At the end of the sleeve is drilling down into the underground pipe, OCTG Casing  and cementing wall with cement, and then with the alignment target layer
perforating guns, the oil flow through the rock, cement, casing into the well bottom, then enter the tubing to the ground.

Sucker rod centralizers is downhole tool

Sucker rod centralizers is anti-pumping wells eccentric wear downhole tool for partial mill pumping wells, especially for rod and points or more partial grinding deviated directional wells and pumping, sucker rod and points hereinafter, with nylon rod centralizer body fit, preventing side wear better. By the coupling rod centralizer, centralizer sleeve, pup joints. Sucker rod centralizer having flexible and strong, it is in contact with the tubing wall, rod and tube may reduce friction, enhanced oil pumping life.

Part of the Drill String Components

Drilling tools drill pipe is connected to power transmission lever. Usually part of the drill string components are: drill, drill collars, drill Pipe,drilling stabilizers, special fittings and kelly. The basic role of the drill string is: (1) from under the drill bit; (2) applying WOB; (3) the transmission of power; and (4) conveying the drilling fluid; (5) special job: squeeze cement, processed downhole accidents.

Sucker rod pumping wells are elongated rod

Sucker rod pumping wells are elongated rod, then light it on the bar, then under the pump from the power transmission role. A single 7.6 or 8 meters in length, the material is generally high carbon steel, hard chrome plated, with internal threads in the hoop tubing connected on a root has been extended to an underground reservoir of the piston, reciprocating motion to pump oil through the present the oil length generally about two kilometers to the Shengli Oilfield, for example, Sucker Rod Pump Unit Controller include pumping unit, sucker rod pump
