The sucker rod is an elongated rod of the pumping well, which is connected to the polished rod and is connected to the pump to transmit power. The length of the sucker rod is 7.62 or 8 meters, 9.14m. The material is generally low-carbon alloy steel after quenching and tempering. It is connected with the internal thread hoop in the oil pipe and extends to the piston at the underground oil layer. Reciprocating motion to pump oil. The current length of the oil well is generally about two kilometers, taking Shengli Oilfield as an example, the deepest is more than 3,000 meters.
The sucker rod is used to transfer the energy of the pumping unit from the ground to the pump to achieve the purpose of lifting the liquid. The strength, service life and characteristics of the sucker rod directly affect the ability of the pumping unit.
The sucker rod is the slender rod of the pumping unit well and is one of the important components of the pumping system. The sucker rod is an important part of the rod pumping equipment. The sucker rod is connected to the sucker rod column through the coupling, and the upper rod is connected to the pumping unit through the light rod, and the plunger of the pumping pump is connected to the bottom, and the function is to transmit the reciprocating motion of the ground pumping unit to the downhole oil pump.
Sucker rod application
The single length of the sucker rod is 7.6 or 8 meters, and can also be customized according to customer requirements. The material is generally hard chrome plated on the surface of high carbon steel. It is connected with the internal thread hoop in the oil pipe and extends to the piston at the underground oil layer to pump oil through reciprocating motion. The current length of the oil well is generally about two kilometers. Take Shengli Oilfield as an example, the deepest is more than 3,000 meters.
Main features of hollow sucker rod:
Increase the effective stroke of the plunger, improve pump efficiency and increase oil production.
Reduce the number of workovers and well washing, avoid high-condensation, high-wax oil wells, wells, and other accidents.
The structure is reasonable and the sealing is reliable. The mechanical properties reach the D-level rod level.
