| Abstract: | Closed loop geothermal power generation system has been proposed to solve the energetic problem and to develop renewable resources. The system, whose underground part forms a closed system by putting casings in the whole well, overcomes the limitation in traditional geothermal power generation and hot dry rock technology which are subject to geological conditions. It is a newly developed geothermal power generation system, is environmentav friendly and independent of location. ERD technology is used for drilling in the underground part, while the well's profile structure is optimized by applying suspended chain line. The technological requirements for underground connection are suggested. Moreover, technologies of lateral well and expanded casing are applied for cementing, wholse formula has been designed and tested. The thermal conducting fluid is optimized, and the generating efficiency of ORC is calculated. |
| Keywords: | closed loop geothermal power generation drilling and completion technology cement heat conducting fluid organic rankie cycle |
