摘　　要：元城油田开发进入中后期以后，随着综合含水的逐渐上升，井筒腐蚀日趋严重，套损井逐年增多，严重影响了油井的正常生产。介绍了膨胀管补贴技术原理、新型的膨胀管材及主要部件技术以及该在元城油田的现场应用。结果表明．膨胀管套管补贴技术解决了多井段套损漏失导致油水井不能正常生产的矛盾。该技术的试验成功，为油田老井的恢复及再生产提供了一个新的技术手段。With the development of Yuancheng Oilfield getting into the mid-late period,the comprehensive water cut rise gradually, the wellbore corrosion becomes more and more serious and the casing-damaged wells in- creased year by year. These have affected the normal production of oil wells. This paper introduces the principle of solid expansion tube repairing technique, the new material for expansion pipe, the technology of main compo- nent and the application of yuancheng oil field. The results show that the solid expansion tube repairing tech- nique can solve the conflict with casing leak leading to unable normal production. The test success of this tech- nology provides a new technical means for the old wells＇ recovery and reproduction.
