Application of eccentric wear of highly deviated well in Zhuangxi oilfield

With the quickly increased number of highly deviated wells in Zhuangxi oilfield, the wear of rod string and tubing in pump well is continuously becoming serious. In this case, the study of eccentric wear has been put into practice. Through anti-eccentrically worn technology and matching drilling technology including depth-dumping well and other wells, obvious eccentric wear effect has been achieved.
