South West Six Movable Method Described In The Remaining Oil

In this paper, by analyzing the well comprehensive information on the core, select seven different wells core core samples for laboratory testing. The main effects of different penetration levels and sedimentary microfacies (river sand, the main sand, non-main reservoir sand and the sheet) the effective permeability and irreducible water saturation and effective permeability and air permeability, irreducible water saturation and oil-water span of two-phase effective permeability and residual oil saturation of the relationship between the establishment of a mathematical model of oil-water relative permeability is given the formula for calculating the curve. At the same time, according to calculations prepared a computer program to calculate the residual oil distribution movable. Block in the test run, with the relevant core information confined contrast, moving the remaining oil to determine the extent of error saturation. Research of mathematical model of relative permeability curves, you can speed up the pace of history matching to improve the fitting accuracy and shorten the cycle of history matching is to guide potential block an important basis for the adjustment.
