摘要
断层模式地热抽采可利用热储层的天然裂隙带作为地热流体的传输通道,是一种地热高效抽采的方式,其抽采过程中热储层的温度、渗透率演化等对地热抽采效率、地热井稳定性与地热抽采寿命等尤为重要.通过理论建模、工程仿真方式对断层模式地热抽采进行了研究,获得了热储层温度和渗透率的演化趋势,为断层模式地热抽采工作提供了理论依据.
Abstract
Geothermal extraction in fault mode can take advantage of the natural fracture zone of geothermal reservoir as the transmission channel of geothermal fluid,which is a highly efficient way of geothermal energy extraction.The temperature and permeability evolution of geothermal reservoir during the extraction process are particularly important to the efficiency of geothermal extraction,the stability of geothermal well and the life of geothermal extraction.Through theoretical modeling and engineering simulation,the geothermal extraction in fault model was studied,and evolution trend of geothermal reservoir temperature and permeability was obtained,which can provide a theoretical basis for geothermal extraction in fault model.
