摘　　要：八面河西南区沙四段4-6砂组古地貌为北低南高的格局,今构造为一洼一隆两斜坡的特征,地层由北向南总体抬升减薄。通过岩心描述及岩性图版重新修订,明确沙四段4-6砂组沉积微相及储层展布规律。The paleogeomorphology of the 4-6 sand formations of the fourth member of Shahejie Formation in the southwest Bamianhe area was low in the north and high in the south.The present structure is characterized by one depression,one uplift and two slopes.The strata are mostly uplifted and thinned from north to south.Through core description and revision of lithology chart,the sedimentary microfacies and reservoir distribution pattern of the 4-6 sand formations of the fourth member of Shahejie Formation are defined.
