AbstractThere is a rich geothermal energy in Yangyi area of Tibet and the potential energy of single well can be up to 10 MW. Utilization of Enhanced Geothermal System(EGS) technology in the exploitation of deep geothermal energy can alleviate the western energy
Other Abstract西藏羊易地区具有丰富的地热能,单井开发潜力接近10 MW,对其深部热储进行EGS开采,可缓解西部能源紧缺问题。本文建立二维理想EGS开发模型,探讨深层地热开采过程中开采流量、注采方式、注入温度等参数对热储温度场分布及开采寿命的影响。基于羊易温度信息设计了12个数值模型,对比研究发现,开采流量对EGS开采的影响较大,为保证开采50年内的商业利用价值,最大开采流量应控制在0.028 kg/s以下;考虑到钻井成本,注采方式的选择以高注高采和中注高采为最佳;注入温度对热储开采影响较小,可选择40℃-80℃之间任意
