摘　　要：沉积微相研究是认识储层各种物性特征的重要基础。以岩心和测井分析资料为基础,通过对Ⅵ、Ⅶ油组的岩石类型及其组合、沉积构造、生物特征及粒度分布特征等沉积相标志的综合研究,确认目的层为一套扇三角洲沉积体。可进一步分为三角洲前缘及前三角洲两个亚相,其内主要发育水下分流河道、水下分流河道间、河口砂坝、远砂坝、席状砂及前三角洲泥微相。研究表明河口砂坝、水下分流河道沉积储层物性较好,远砂坝、席状砂砂体物性相对较好。反映了沉积微相对研究区储层物性特征起着重要作用。sedimentary microfacies study is the understanding of reservoir haracteristics of the various properties of an important foundation.On the basis of the materials of rock and well logging.It is held that Ⅶ Oil Formation of He-3 member in shuang jiang oilfield is a set of fan-delta deposition according to the analysis of various of facies marks,including rock types and their combination,sedimentary structure,biology feature and grainsize distribution feature of sandstone and so on.It can be divided into two s...
