摘要
Abstract
By analyzing the eccentric wear of rods and tubing of rod pumped well in Zhangtianqu oilfield,it＇s considered that the main reasons for the eccentric wear of rods and tubing include the well track,column collapse,operational parameter and others factors.Therefore,the quaternity resistant-side-wearing technical policy is developed,which consists of ground-parameter adjusting,downhole optimal design,fixing resistant-side-wearing tools and strengthening site supervision.The working system of the rod pumped well is long stroke and low stroke per minute.The parameter of sinker bar is optimal-designed.The other two measures use the resistant-wearing rod and collar centralizer and strengthening site supervision.The treatment countermeasures have achieved good results in the field,effectively extending the operating cycle of pumping wells.The control measures can provide certain references for the well production.关键词
