Zusammenfassung:	To provide a geothermal power production process using a closed loop system.SOLUTION: A process for producing electric power includes injecting a first heat transfer fluid through an injection well 100 to a geothermally-heated formation 200 that contains a second heat transfer fluid. The first heat transfer fluid is heated via indirect heat exchange in an interwell run 110, which is fluidly connected to the injection well, and disposed within the geothermally-heated formation. Thermal energy contained in the recovered first heat transfer fluid is converted in a power production unit 140 that is fluidly connected to the injection well and a production well 120. The interwell run, in some embodiments, includes a plurality of heat exchange tubes disposed within a sewing machine casing or drill pipe.SELECTED DRAWING: Figure 1 【課題】閉鎖ループシステムを用いた地熱電力生成プロセスを提供する。【解決手段】注入ウェル１００を通じて第１の熱伝導流体を、第２の熱伝導流体を含む地熱で加熱された層２００に注入する事を含む電力生成プロセス。第１の熱伝導流体は注入ウェルと流体接続された中間ウェル経路１１０において間接的熱交換を介して熱せられ、地熱で加熱された層内に配置される。回復された第１の熱伝導流体内に含まれた熱エネルギーは注入ウェルおよび生成ウェル１２０と流体接続した発電ユニット１４０内で変換される。中間ウェル経路はいくつかの実施形態では、ミシンケーシングまたはドリルパイプ内に配置された複数の熱交換チューブを含む。【選択図】図１
