摘要
渤海湾盆地埕岛油田是我国极浅海地区第一个投入开发的大油田。综合应用沉积岩石学、地质学等多学科理论,从岩心描述入手,结合区域地质背景、岩心分析和测井等资料,全面分析了埕岛油田馆上段的岩石学特征、沉积构造特征、测井曲线特征和古生物特征等,确定了该区馆上段砂岩为河流相沉积,并运用多种河相判别参数对埕岛油田馆上段储层进行判别,进一步确定了该储层的亚相类型为曲流河,在此基础上总结了4种沉积微相特征和主力小层古水流方向,并对不同沉积微相的开发特征和开发效果进行了评价。
The Chengdao Oil Field is the first shallow oil field put into development in China . Applying sedimentary petrography and geology, the sedimentary petrographical and structural characteristics, logging curves and palaeontologic features of the Neogene upper Guantao formation （Ng） have been studied on the basis of geological setting, core description and logging analysis. Sands of the upper Ng belong to fluvial facies and the subfacies is meandering river by many identification parameters of river types. Then , 4 types of microfacies have been concluded, the palaeocurrent directions of the main unit have been pointed out, and the deve-lopment characteristics and effects of different microfacies have been evaluated .
