| 摘 要： | 综合研究伊通盆地鹿乡断陷双二段储层的岩性、含油性和含油饱和度,确定了适用于本区的含油饱和度计算方法,并与实际含油性进行了对比,分析了沉积和构造对含油性的影响。研究区双二段含油储层的岩性以粉砂岩、细砂岩和砂砾岩为主,含油级别为荧光级以上。根据阿尔奇公式计算出的含油饱和度大部分与实际的含油性相符合,并将含油饱和度70%、50%和38%值作为本区气层、油层、油水层和水层的区分标准。本区储层的含油性受到沉积和构造两方面的控制,沉积作用主要控制储层的岩石结构和物性,构造控制油气的聚集,即在构造高部位,实际含油饱和度比计算结果要高,而在构造低部位,实际含油饱和度比计算结果要低。

| Abstract: | The comprehensive study of lithology，oil-bearing level and oil saturation of the 2nd Member of Shuangyang Formation established the suitable calculation method of oil saturation for block-C． The effect of deposi- tion and structure on oil-bearing level was analyzed compared with actual oil-bearing level． Oil reservoir rocks of the 2nd Member of Shuangyang Ｒeservoirs in the studied area are mainly siltstone，fine sandstone and glutenite． Oil levels of reservoirs are all above fluorescence． Most of calculated oil saturations，based on Archie，are consistent with the actual oil saturation． Oil saturation of 70%，50% and 38% are regarded as the distinguishing criteria for gas layer，oil layer，oil-water layer and water layer． The oil-bearing level of reservoirs in the studied area is con- trolled by both deposition and structure． The deposition mainly controls rock textures and physical properties of the reservoir，while structure controls hydrocarbon accumulation，i. e． ，the actual oil saturation in structural highs is higher than the calculated result，while in structural lows is lower than the calculated result． |
