Study on the Determination of the Separated Layer Water Injection Based on the Grey Synthetic Degree

Abstract:

The determination of the rational layered water injection intensity is the basis to stable oil production and high-yield in oil field. This article analyzes the various influential factors of the separated layer water injection intensity, using grey synthetic degree to determine the dominant influential factors. The weight value is obtained by normalization, each influence factor is quantization. Using grey correlation analysis method to determine the plane dividing coefficient and the vertical dividing coefficient, a reasonable stratified water injection intensity formula is got. This method considers the impact of these factors which consist of permeability, the measure transformation coefficient, perforation thickness, injector producer distance, location coefficient and the number of injector and producer. The problem which the contradiction exists in the same layer or between the layer and layer is obvious in the D block through combining with the current water injection development, reasonable dividing coefficient of block is established, a reasonable stratified water injection intensity formula is got, making well block reasonable injection and increasing adjustment effect of water flooding.
