摘　　要：天津地区具有丰富的地热资源和油气资源,20世纪90年代大港石油集团公司为寻找石油在塘沽地区开凿了一大批石油开采井,随着石油资源的日益枯竭,多数油井均已废弃。本文结合该区地热地质资料和油井井身结构,探索将废弃的石油井改造为地热井,并通过T38-1、T38-2井成功改造实例证明其可行性,为类似工程提供了借鉴。Tianjin area is rich in geothermal resources and oil and gas resources. In 1990 s,Dagang Oilfield Co.,Ltd.built a large number of exploited wells for oil prospecting in Tanggu area. With the oil resource exhausting,most of the wells have been abandoned. Combined with geothermal geological datas and oil well configurations,the methods of transforming abandoned oil wells into geothermal wells is explored in this paper,the feasibility is proved through the successful transformation examples of T38- 1 and T38- 2 wells.
