The Study on Water-Flooded Mechanism and Logging Data Response Characteristics of Water Displacing Oil Tests of High Permeability Reservoirs

In order to investigate water-flooded mechanism and logging data response characteristics, a series of water displacing oil tests of high permeability reservoirs are performed. Rock pyrolysis, gas chromatograph of saturated hydrocarbon and fluorescent microgram of samples are developed. Meanwhile, variation ruled and trend of rock pyrolysis, gas chromatograph of saturated hydrocarbon and fluorescent microgram followed by water cut increasing are analyzed. Logging data response characteristics of high permeability reservoirs are discussed. The study provides theoretical foundation for evaluating different range of water-flooded of high permeability reservoirs by logging data.
