Abstract

Abstract: Injecting natural gas to enhance oil recovery has a good application prospect, but at present, there is a lack of corresponding development effect evaluation index system and standard for natural gas flooding reservoirs, and it is impossible to evaluate the development effect correctly, objectively and scientifically. According to the industry standard of "oilfield development level classification" and the evaluation index system of water flooding and CO₂ miscible flooding development effect, 10 evaluation indexes for evaluating the development effect of natural gas flooding reservoirs are selected: recovery improvement range, oil exchange rate, production increase ratio, reserve utilization degree, reserve control degree, pressure maintenance level, gas storage rate, gas-oil ratio increase ratio, stage injection-production ratio and gas injection timing. Combined with the geological characteristics, production performance and gas injection development characteristics of W natural gas drive reservoir, the evaluation index system and evaluation standard of natural gas drive development effect are established. The development effect evaluation method of natural gas flooding reservoir based on fuzzy comprehensive evaluation decision is established by using analytic hierarchy process, fuzzy transformation principle and maximum membership degree principle. The traditional single index and qualitative development effect evaluation are transformed into multi-factor and quantitative development effect evaluation. The application example shows that the evaluation index system and evaluation method of natural gas flooding development effect are feasible and effective, and have certain guiding significance for the evaluation of the development effect of the same type of natural gas flooding reservoir.

Key words: natural gas drive reservoir, development effect evaluation, evaluation index system, analytic hierarchy process, fuzzy evaluation strategy
