The article investigates the effect of a local change in the parameters of relative phase permeability (RPP) in oil reservoirs. A computer hydrodynamic simulation of oil field development was performed using the example of a homogeneous model reservoir with two wells – producer one and injection one. Changes in residual water and oil saturation as well as in the scales of RPP curves of water and oil were studied. The effects of variations in the localized areas near the producer and injection wells and in the interwell space are discussed. The effects of inhomogeneity of globally relative parameters of RPP were also analyzed. The maps of oil saturation were built, and the graphs of bottom hole pressure for the injection and producer wells were examined. As a result of the numerical calculations, it was established that the influence of inhomogeneous parameters on the integral characteristics is negligible and on the dynamic ones it is significant. Thus, in some cases RPP inhomogeneity can be neglected in reservoir simulation, and it is sufficient to use refined permeability or skin factor.
