摘　　要：分析了根据稠油热采井在生产过程中易出现套损的情况,并根据目前热采井套损后,采取的常规修复方法是大修作业,对套管进行补贴,该技术修井周期长,费用高;为此根据我们研制的化学堵漏剂,分析研讨了该技术在稠油井进行套管补贴的可行性,运用化学堵漏剂已经成功的在稀油井实施了套管补漏,经过现场试验,证明对套管补漏是可行的。This paper analyzes casing damage appeared in the production process easily in the heavy oil thermal recovery wells,At present,the conventional repair method is to overhaul operations and casing patch after casing damage occurred in the thermal recovery well,The method needs long cycling time and high cost,for this reason,we developed a chemical blocking agent and discussed the feasibility of casing patch in the heavy oil.Chemical blocking agent has successfully used for casing trap in the thin oil,After field tests,casing trapping is proved to be feasible.
