Examples
- ( 3 ) in the hot dry rock geothermal energy extraction system , with the heat extraction , the temperature of the injection lower temperature water go up , but the speed descend gradually
( 3 )在高温岩体地热) l :发系统中，随开采时间的延长，注入的低温水的温度升高的速率逐渐减小。 - The hot dry rock geothermal energy is a r . ew clean energy and have excellent development prospects , but is not yet exploited on large - scale in our country then to mankind : the theories and technique of the heat extraction all belong to the new task in the new field , and already have a strong appeal to the international technology worker , and already have obtain certainly achievement , on the basis of study by our predecessors , this paper do the as follows work , acquire the following main result : lx present a many fields coupling mathematics model for solid - flow - heat of 3d blocked medium in hdr
高温岩体地热是我国以至人类尚未大规模利用而又极具广阔开发远景的新的洁净能源，对其进行开发利用的理论与技术都属于新型领域的新型课题，已经吸引了大批的国内外科技工作者的投入，并取得了一定的成果。在前人研究的基础上，本文做了如下工作，获得了如下主要成果： 1 、建立了高温岩体地热开发的块裂介质固、流、热多场耦合数学模型，模型控制方程包括完全耦合的变形方程、渗流方程、热传导与对流方程，描述了热储层的非线性特性。 - 7mpa / km in the center of the zone ( 6 ) in the hot dry rock geothermal energy extraction system , after the system start to operate , the normal stress of crack show the pronounced influence depending on the temperature ' s change in a month , there are a marked drop in temperature nearby the injection well , forming a lower stress area , with the heat extraction , the temperature ' s change even gradually , but the temperature descend quickly nearby the production well , forming a new lower stress area
( 6 )高温岩体地热开发中，裂缝面法向应力受温度变化的显著影响，在系统开始运行的一个月内，注入井附近区域其温度降低较快，形成低应力区;随开采时间的延长，其温度变化逐渐平缓，而生产井附近区域温度降低加快，逐渐形成新的低应力区。 - 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。 - ( 7 ) in the hot dry rock geothermal energy extraction system , the fracture width widen gradually with the heat extraction , after the system start to operate , in a month the width change rapidly , the growth rate exceed 100 % , and then the change become even , until 3 year , the variety is very small , almost towards to stability
( 7 )在高温岩体地热开发中，其裂缝宽度是随地热提取而逐渐加宽的，在开始运行的一年内，宽度增长迅速，其增长率达到100 %以上，然后变得平缓，到3年后，变化很小，几乎趋于稳定。
