摘要
利用铸体薄片、扫描电镜和压汞等资料,对扶新隆起带扶余油层进行了储层特征研究。结果表明储层类型主要为特低孔-低孔、非渗-超低渗储层,物性受成岩作用、沉积作用、微观孔隙结构等多因素影响。孔隙类型以次生孔隙为主,溶蚀作用是其主要成因。选用物性、岩性、微观孔隙结构等多个参数,将扶余油层储层划分为3类,其中Ⅱ类储层物性中等,是扶余油层产能贡献的主体储层,为今后研究的重点。
Through the information offered by casting slice,scanning electron microscope and mercury injection test and so on,characteristics of Fuyu Oil Layer in Fuxin Uplift of Songliao Basin is researched,the results show that the types of reservoir are super low porosity and low porosity,non-infiltration and ultra-low permeability,reservoir physical properties are influenced by diagenesis,sedimentation,microscopic pore structure,main pore types are secondary porosity and dissolution are its main causes.choose properties,lithology,microscopic pore structure and so on,the reservoirs of Fuyu Oil Layer are divided into three categories,the second class reservoirs properties are medium,which are the main reservoirs of Fuyu reservoir for capacity contribution,and are also the focus of future research.
