Sucker rod profile

The sucker rod is an elongated rod member of a pumping well. It is connected with a light rod and a sucker pump at the bottom to transmit power.


The single length of the sucker rod is 7.62 or 8 meters and 9.14m. The material is generally low-carbon alloy steel. After quenching and tempering, the oil pipe is connected with the internally threaded hoop one by one to the piston at the underground oil layer. Reciprocating motion to pump oil. The current length of oil wells is generally about two kilometers, with Shengli Oilfield as an example, the deepest is more than 3,000 meters.
