Succeeded in the transformation of the crushing process of the sucker rod righting block in the No. 1 Oil Production Plant of Henan Oilfield

Since the Production Preparation Team of the No. 1 Production Plant of Henan Oilfield has implemented the reformation of the crushing process of the sucker rod righting block, up to now, 60,075 of the various types of pumping rods have been overhauled, and there has been no accident of repairing and scrapping the sucker rod caused by the crushing and righting blocks. It marks the success of this technological transformation. It is reported that the repair and maintenance team of the oil pipe rod has improved the efficiency of repair work and reduced the labor intensity of workers. The time required to crush a sucker rod straightening block has been shortened from 8 minutes to 2 minutes, and the quality of repair and work efficiency have been significantly improved.
