Method of composite-facies-controlled model used in the creative model of oil and gas reservoir parameters

Oil and gas sandstone reservoirs are not only controlled by sedimentary microfacies,but effected by conformation and lithologic characters.The fact is reflected in the oil/gas/water distribution.Using sedimentary microfacies and oil/gas/water distribution to control oil/gas sandstone reservoir physical properties,the paper puts forward a method of composite-facies-controlled model to predict physical property parameters of sandstone reservoirs between wells and to research the lateral distribution of sandstone thickness,effective thickness,reservoir porosity,permeability and saturation by building a model of oil/gas reservoir physical property parameters.The essence of the method is to achieve parameter prediction between wells compositely controlled by geological and oil/gas.The method is suitable for the oil/gas reservoir parameters discription without enough wells and is a practical and technical method of reservoir description.
