摘　　要：在对金湖凹陷西斜坡阜二段储层研究过程中，发现岩心中存在一定数量的由牵引流造成的正韵律砂体，砂体平面分布上存在多条厚度较大的砂体条带，并且存在定向物源和大量残存的补给水道，均与前人认为的滨浅湖砂坝微相特征不相符。综合研究认为阜二段三砂层组地层发育了一套外源滨浅湖沉积体系，包括3个亚相、7种微相，并在单井相、连井相、平面相研究基础上给出了沉积体系模式，从剖面和平面2个方面描述了沉积相展布特征。In the reservoir researches of the Fu No. 2 Member in the west slope of Jinhu Sag, there are a certain number of positive rhythm sandbodies built by traction current in well core, and moreover many much thicker hori- zontal sandbody belts are found, so the directional source and a great many residual feeder channels are discovered and not coordinate with the previously thought microfaeies characteristics of shore-shallow lake sand bars. The inte- grated studies show that a set of allogenie shore-shallow lake sedimentary system are developed in No. 3 Subinterval of Fu No. 2 Member, including 3 subfaeieses and 7 micro faeieses, and furthermore the models of the sedimentary system are presented on the basis of individual well facies, joint well facies and plane facies. Finally the distributa- ry features of the sedimentary facieses are described in both horizontal and vertical aspects.
