摘　　要：基于TOUGH2数值模拟器中存在处理复杂地质条件难的问题,提出了将三维地质模型与TOUGH2数值模型耦合的具体思路和方法,并在Windows平台上编制了相应的程序,利用该程序可以直接将地质模型(如GMS和Petrel建立)与TOUGH2的数值模型进行有机融合,并进行了算法验证。通过CO2地质储存的实例,可以看出地层构造对CO2的空间运移起着控制作用,模拟结果显示CO2会沿着背斜面地层进行运移扩散。因此通过此转换程序,能够增强TOUGH2模拟器处理地层起伏、断层、褶被等常见地质构造,以及地质属性随空间变化的地质体,提高了模拟器的使用效率。It ’s difficult to deal with complex geological conditions in TOUGH2 simulator, therefore,the method of a complex 3D geological model and coupling pattern numerical simulation were put forward,and the authors developed the corresponding program on the Windows platform.It can be used to the geological modeling created by GMS or Petrel software coupling TOUGH2 numerical model. Through the instance of carbon dioxide （CO2 ）geological storage,it can be seen that the stratigraphic structure plays a controlling role of CO2 space migration,the simulation results show that CO2 can spread along the back slope formation.Therefore,the coupled method,which provides a new approach and methodology to improve the efficiency of this simulator to deal with complex geological structure, such as ups and downs stratum,fault,fold and geological attribute of geological body chang according to the space.
