Oil reservoir injection-production parameter adaptability evaluation method and device, storage medium and equipment

Abstract

The invention provides an oil reservoir injection-production parameter adaptability evaluation method and system, a storage medium and equipment, and the method comprises the steps: determining a comprehensive evaluation index based on the correlation between the recovery degree of an oil well with formulated injection-production parameters and geological parameters, carrying out the positive and negative correlation processing, and calculating a weight coefficient; calculating an oil reservoir comprehensive evaluation index coefficient according to the positive and negative correlation processing result and the weight coefficient; dividing grading boundaries of the oil reservoir and the evaluation indexes based on the correlation between the water content change condition of the oil well and the comprehensive evaluation index coefficient of the oil reservoir; calculating a seepage field evaluation coefficient and a total adaptation coefficient; and according to the correlation between the recovery degree and the total adaptation coefficient, determining an adaptation limit, and evaluating the injection-production parameters and the oil reservoir unadapted well to obtain an evaluation result. According to the method for judging the adaptability of the oil reservoir injection-production parameters, multiple factors are comprehensively considered, the adaptability of the oil reservoir injection-production parameters is judged quickly, accurately and quantitatively in a standardized mode, scientific judgment of the adaptability of the oil reservoir injection-production parameters is achieved, and the implementation effect is ensured.
