Anti-break Sucker Rod
Introduction
Anti-break sucker rod is 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 sucker rod and the anti-break polished rod can solve the tripping problem of rod string caused by alternating torque.
