3 , carry out detailed numerical simulation and analysis for heat extraction of deep - seated hdr based on the tengcong prefecture , reach the major variety rule of rock mass stress , temperature , fracture width depending on the heat extraction . ( 1 ) in the hot dry rock geotherraal energy extraction system , transportation of energy and flow of water arise mainly through the fracture , the lower temperature water attain the high temperature from the injection well to production well through conduction convection and take away the thermal from wall rock 3 、认真地对腾冲高温岩体地热开发进行了数值模拟计算和分析，得出了地热开发过程中岩体应力、温度以及裂缝宽度随地热提取的变化规律等重要结论： ( 1 )在高温岩体地热开发系统中，能量的运移、输送与水的流动主要通过裂缝面发生，注入的低温水在流到生产井的过程中，发生传导、对流、吸收围岩热量，达到升温的目的。
