More Information
Summary:The utility model provides a sucker rod. The sucker rod comprises a sucker rod body and rod heads arranged at the two ends of the sucker rod body. The rod heads are provided with external threads used for being connected with internal threads arranged on a coupling. The diameter of the sucker rod body is larger than 28.58 mm. Due to the fact that the size of the diameter of the sucker rod body is larger than that of the diameter of an existing sucker rod, the largest load borne by the sucker rod body is increased, lifting tension is increased, the service life of the sucker rod is prolonged, and the process requirement for oil well ultra-deep exploitation is met.
