Research on Quantitative Recognition Method for Preferential Percolation Path by Tracer Experiment

To effectively block preferential percolation path for solving the injected solution cross-flow and ineffective circulation along preferential percolation path, has great significant to improve the oil-field development efficiency and realize oil stabilization and water control. In this paper, the method of simulation and tracer was used to research the dynamic reflection of preferential percolation path. The major parameters and relative characteristics of the preferential percolation path were analyzed. The assessment criterion and results describe of preferential percolation path based on oil reservoir numerical simulation were established. Quantitative recognition for preferential percolation path can be realized. The research results have very important significance for preparing rational measures of water control at late stage of oil field development.
