Method for analyzing dynamic and static communication conditions of sand body of oil-water well

The invention relates to an oil-water well sand body dynamic and static connectivity condition analysis method. Static connectivity judgment is carried out; the sand body static connectivity degree is obtained according to the product of the sand-to-ground ratio S, the sand body distribution connectivity degree and the longitudinal overlapping connectivity degree; dynamic connectivity judgment is carried out; determining the perforation perfection degree, the water drive reserve control degree and the injection-production corresponding degree of each producing well; the obtained sand body effective thickness, porosity, permeability, sand body static connectivity degree, perforation perfection degree, water drive reserve control degree and injection-production corresponding degree serve as evaluation parameters, the evaluation parameters are normalized and weighted, and the sum of products of the normalized evaluation parameters and the corresponding weights serves as a static and dynamic connectivity coeffici
