摘　　要：针对特种油开发公司热采井套管损坏日益严重,制约了热采油井的正常生产这一问题,引进了套管热应力补偿器,并在现场198口热采井中进行了应用,有效缓解了热采井的套管损坏,使套管损坏率下降了10个百分点以上。Casing failure in thermal recovery wells of the Special Oil Development Company is getting serious day by day, and restricts normal production in these wells. Thermal stress compensator for casing has been imported. It has been used in 198 thermal recovery wells. Casing failure problem is mitigated effectively, and the rate of casing failure reduces by over 10 percent.
