按河流相、湖底扇（浊积） 相、三角洲相、滩坝相、冲积扇相、扇三角洲相和非碎屑岩这７ 种类型储集层和它们与低粘（ ＜３ｍＰａ·ｓ）、中粘（３ ～３０ｍＰａ·ｓ ） 、高粘（ ＞３０ｍＰａ·ｓ）与高渗（ ＞ ６００ ×１０－ ３μｍ２） 、中渗（１００ ×１０－ ３ ～６００×１０ － ３μｍ２） 、低渗（ ＜ １００ ×１０－ ３μｍ２） 的组合，统计研究了我国水驱油田的平均空气渗透率、平均孔隙度、平均地下原油粘度、平均地面原油密度、地质储量、可采储量、至１９９５ 年底累积采油量、至１９９５ 年底剩余可采储量、平均采收率、平均采出程度、平均可采储量采出程度等静、动态参数与指标。我国水驱油田平均采收率（ Ｒ） 为０ ．３１ ，按渗透率、粘度界限由大到小排列为高渗低粘（ Ｒ为０ ．５） 、高渗中粘（ Ｒ为０ ．３８１） 、中渗中粘（ Ｒ为０ ．３１７） 、中渗低粘（ Ｒ为０ ．３０４） 、低渗中粘（ Ｒ为０．３０２）、中渗高粘（ Ｒ为０．２８９） 、高渗高粘（ Ｒ为０ ．２８）、低渗低粘（ Ｒ为０ ．２１） 。河流相和三角洲相储集层是我国主体开发储集层，也是今后进一步挖潜的主要对象。滩坝相和扇三角洲相可采储量采出程度明显偏低，有待于加大开采强度。
The seven types of reservoirs, ie, fluvial facies, sublacustrine fan (turbidite) facies, delta facies, dyke dam facies, alluvial fan facies, fan deltaic facies and non-clastic rocks, and their relationships with low viscosity (<3 mPa · s) Medium viscosity (> 30 mPa · s), high viscosity (> 30 mPa · s) and hypertonicity (> 600 × 10-3μm2), medium permeability (100 × 10-3-600 × 10-3μm2) 100 × 10- 3μm2). The average air permeability, average porosity, average underground crude oil viscosity, average ground crude oil density, geological reserves and recoverable reserves of water-flooding fields in China were statistically investigated. By the end of 1995, By the end of 1995, the remaining recoverable reserves, average recovery rate, average recovery rate, average recoverable recovery rate and other static and dynamic parameters and indicators. The average oil recovery (R) in our country is 0. 31. Permeability and viscosity range from high to low low viscosity (R = 0.5), high viscosity (R = 0.381), medium permeability (R = 0.317) Medium permeability low viscosity (R 0.304), low permeability medium viscosity (R 0.302), high permeability (R 0.289), high permeability high viscosity (R 0.28), low permeability Low viscosity (R is 0.21). River facies and delta facies reservoirs are the main reservoirs for development in China and are also the main targets for further potential tapping in the future. The recoverable reserves of beach dam facies and fan delta are obviously lower, and the intensity of recovery needs to be increased.
