Abstract

Abstract: Discrete fracture network models have become the focus of much research owing to their ability to better characterize the non-homogeneity of fractured reservoirs. The FILTERSIM multi-point geostatistical method was introduced into the discrete fracture network model to overcome the deficiencies of the Monte Carlo method and to provide a fracture network model for the subsequent numerical simulation of the flow. Based on the oil-water two-phase flow model, the finite-element numerical solution of the degree of oil-water two-phase saturation was derived. Taken together with the constructed fracture network model, the dynamic process of the oil displacement by water and pattern of moisture content increase during single-well injections were studied. The study showed that compared with the homogeneous model, injection of water through the channels of the fracture network in the discrete fracture network model led to the premature emergence of water from oil wells. After the emergence of water from the oil well, the two models exhibited consistent patterns of water cut increase.

Key words: discrete fracture network, multi-point geo-statistics, numerical simulation, fractured reservoirs, oil-water twophase flow
