Numerical Investigation of Chemist Flooding in 3D Naturally Fractured Medium

초록

This article presents a numerical analysis of chemist flow in a discrete fractured system using 3D discrete fracture network, automated quadrilateral meshing, and streamline routing. The trajectories of chemists are visualized by OpenGL. Non-reactive masses are transported between two wells and then the main flow patterns are examined. The non-reactive chemists move selectively along intersecting lines or fracture planes in the direction of decreasing pressure gradient. The more heterogeneous the system is, the more severe the channeling occurs. A small region of one fracture comes into being flowing zone while only 3040% of all fractures affect the transport of solutes similar with a real heterogeneous case.
