What is sucker rod?

Sucker rods are long, slender, solid rods used in the oil and gas industry to transfer energy from a surface pumping unit to downhole reciprocating pumps to lift oil from a well. They are typically made of high-strength steel and are available in various grades and sizes depending on the specific well conditions and requirements.

Sucker rods are connected end-to-end to form a continuous rod string that extends from the surface to the bottom of the well. The rods are attached to the pump plunger at the bottom of the well and are moved up and down by the surface pumping unit to lift oil to the surface.

Sucker rods are designed to withstand high tension, bending, and compression forces during the pumping operation. They are also corrosion-resistant and have a long service life, making them a cost-effective solution for artificial lift applications in oil and gas production.

Regular maintenance and inspection of sucker rods are necessary to ensure their safe and efficient operation. Proper handling, installation, and storage practices are also important to extend the life of sucker rods and prevent premature failure.
