摘要(Abstract)：

根据取心资料、测井资料、古生物分析、元素分析、岩石薄片分析、粒度分析等相因素分析,查明了该区研究层段发育的沉积相、亚相、微相类型及特征,建立了相应的识别标志。该区黑帝庙油层发育的沉积相类型有曲流河三角洲和湖泊两种沉积相类型。在平面上,运用层序地层学和地球物理手段预测了砂体的平面分布特征,分析了其在平面上的演化规律。从嫩江组三段早期至嫩江组四段晚期,敖浅1—茂702区块沉积相总体上呈近东西向展布、南北相带变化明显的特点。总体上构成一个向上变粗的进积序列,反映了湖平面收缩的沉积特征。
Through analysis on coring data,logging data,palaeophyte,elements,rock chips and grain size,this paper determines sedimentary facies,subfacies and microfacies and their characteristics of studies intervals in this area,and establishes corresponding identification signs.Sedimentary facies in Heidimiao Reservoir develops meandering deltic and lacustrine facies.It uses sequence stratigraphic and geophysical methods to predict areal distribution of sandbodies,and analyzes areal evolution rules.From early period of Member 3 to Member 4 in Nenjiang Formation,sedimentary facies of Block Aoqian1-Mao 702 appears as extending in EW direction and changes apparently in NS direction, forming generally coarsening upward propagational sequence,and reflecting sedimentary characteristics of lake level shrinking.
