Abstract

Numerical simulation is very useful in utilizing large scale geothermal energy,predicting reservoir response and optimizing exploitation procedure.Here we describe the OpenGeoSys(OGS)software used to simulate the complex processes in geoscience and hydrological applications,focusing on its application in geothermal energy utilization.OGS is based on an object-oriented finite element method concept and can deal with numerical simulation of thermo-hydro-mechanical-chemical processes in porous media.Case studies related to shallow geothermal energy(temperature and pressure prediction),hydrothermal energy(optimization on the distance between production well and reinjection well,scaling)and hot dry rock(hydraulic fracturing,permeability evolution)are shown with the purpose to help managing geothermal energy utilization.

OpenGeoSys在地热能可持续利用中的原理与应用

数值模拟对大规模利用地热能、预测储层响应和优化开发工艺具有重要意义。本文介绍了用于模拟地球科学和水文应用中复杂过程的OpenGeoSys(OGS)软件，重点介绍了其在地热能利用中的应用。OGS基于面向对象的有限元方法概念，可以处理多孔介质中热-水-机械-化学过程的数值模拟。案例研究涉及浅层地热能(温度和压力预测)、热液能(生产井与回注井之间的距离优化、结垢)和热干岩(水力压裂、渗透率演化)，旨在帮助管理地热能利用。

期刊介绍： Earth Science Frontiers is a bimonthly Chinese academic journal co-sponsored by China University of Geosciences (Beijing) and Peking University. Academician Deng Jun has been the editor-in-chief since its founding in 1994. Each issue of the journal invites special editors to compile theme albums, supplemented by selected free submissions, to fully display the cutting-edge, innovative and basic research results in the field of earth sciences, and publish academic debate articles. With its academic influence and excellent performance, Earth Science Frontiers has won honors such as "China's Most Internationally Influential Academic Journal" and "One Hundred Outstanding Chinese Academic Journals", and has been selected into China's "Excellence Action Plan" project.
