基于多点地质统计的二维裂隙网络溶质运移模拟
Two-dimensional simulation of solute transport in fractured media based on multiple-point geostatistics
摘要
Abstract
In this paper,themultiple point statistical simulationmethod was used to establish and calibrate a synthetic two-dimensionalfracture network model.Also,the generated model was combined with MODFLOW and MT3DMS codes to simulate the flow and solute transport in the fracture network.The simulation results show that the solute in fracture network is transporting strictlyovertimein agreement with the orientation of the fractures.Furthermore, as the conductivity ratio between channel and matrixincreases,the phenomenon of anisotropy and preferential flow becomes much more obvious.It is shown that the multiple-point statistical simulationprovides a powerful toolfor characterizing complicated fracture networks as well as simulatingthe flow and solute transport in fracture networks.关键词
