摘要
以濮城油田为例,对低渗透储层进行了分类评价,根据评价原则及主要参数,将储层分为一般低渗透 层、特低渗透层、超低渗透层、致密层、非常致密层及裂隙-孔隙层六种类型,为进一步认识油层内部结构 特点及合理开发,提高最终采收率提供科学依据。
Low permeability reservoirs are classified and evaluated by taking Pucheng oilfield as an example. According to evaluation standards and the main parameters, the reservoirs are divided into 6 types, including ordinary low permeability reservoirs, ultra - low permeability reservoirs, tight reservoirs, very tight reservoirs and fractured - porous reservoirs. It provides scientific basis for further understanding internal structure of oil layers, rationally developing oilfield and enhancing ultimate recovery factor.
