A New Measurement of Anisotropic Relative Permeability and Its Application in Numerical Simulation

In this paper, we used a self-developed anisotropic cubic core holder to test relative permeability by the unsteady-states method, and introduced traditional numerical simulator. The oil–water two-phase governing equation considering is established, difference discretization carried out. We formed new simulation method. It clear that in heterogeneous rock with millimeter centimeter scale laminae, an tensor. When displacement direction parallel bedding, residual oil saturation high efficiency low. greater angle between bedding strike, lower is, higher curve tends towards rightward shift. simulator showed not only affects breakthrough time sweep range of water flooding, but also has significant influence on overall cut. validated actual oilfield model. could describe law seepage reservoir, depict remaining distribution typical fluvial provide technical support for reasonable injection-production directions.
