Anti-break Polished Rod
Introduction
Ｐolished rod is mainly applicable to deviated well, horizontal well and heavy oil well. Due to the large contact force between sucker rod and tubing, the downward oil has high resistance, it often makes sucker rod difficult to move downwards. The combination of the anti-break polished rod and the anti-break sucker rod can solve the break off of rod string caused by alternating torque.
