【摘要】 综合利用地震、岩心、测井、录井等资料,对宋站南地区扶余油层扶二组的沉积微相进行了研究。根据宋站南地区扶余油层地震属性和地震剖面特征,推测宋站南地区扶余油层为河流相沉积。以沉积岩颜色、岩石的结构特征、组合韵律以及测井曲线特征为划分沉积微相的标志,指出了研究区扶二组发育河道、决口河道、冲积扇和河漫滩4种沉积微相。从油气富集机理上论述了研究区扶二组油气分布主要与相控下的河道砂体和决口河道砂体密切相关,指出了宋站南地区扶二组油田开发的有利相带。更多还原

【Abstract】 The sedimentary microfacies in the Fuyu Ⅱ formation,Southern Songzhan,Songliao Basin have been studied by using the data of seism,core,logging and mud logging.Based on the seismic attributes and seismic profile characteristics of the Fuyu reservoir,it is inferred that the reservoir belongs to fluvial facies sedimentation.The color of sedimentary rocks,structural features of the rocks,combination rhythms and logging curve characteristics are used as the demarcations to divide the sedimentary microfacies and it is concluded that four kinds of sedimentary facies,i.e.fluvial channel,crevasse channel,alluvial fan and alluvial flat are developed in the Fuyu II formation of the study area.According to the mechanism of hydrocarbon accumulation,it is concluded that the oil and gas distribution in the Fuyu Ⅱ formation of the study area is closely related to the sand bodies controlled by the fluvial channel facies and crevasse channel facies,and the favorable facies belts for development in the Fuyu Ⅱ formation of Southern Songzhan area are identified.更多还原
