Hollow Sucker Rod
Hollow sucker rod has hole in the middle and has the characters: chemicals and hot oil can be injected through the inner hole to decrease the viscosity of the oil and the paraffin deposit in the well thus the pump efficiency is increased; The smaller passage and the faster flow velocity can avoid the sand deposit efficiently while use hollow sucker rod in the sand well; Matched with the rodless pump hollow sucker rod can substitute the tubing; Hollow sucker rod can be used to drive the PC pumps as it can bear larger torque.

Continuous Sucker Rod
Continuous sucker rod is not-jointed and made of high quality alloy steel sucker rod with advanced technology whose section is semi-elliptic or round. It has the advantages of high strength, good flexibility and solderability so that it can significantly decrease the failure frequency of sucker rod, the attrition rate with the tubing, improve the workover efficiency, lighten the labor and increase the production of the well. Mechanical performance is equivalent to grade D of and special purpose rod of SM SMR, SU, and SRU. Now the annual usage in Shengli Oilfield is more than 1,000 kilometer.
