摘　　要：综合应用沉积学、岩石学等原理、方法,在对夏子街油田26-35井区克上组的岩石学、测井相分析的基础上,建立了该区目的层的沉积模式。研究区目的层主要发育洪积扇扇顶亚相,其中以主槽、侧缘槽微为主要微相类型,呈片状大面积发育,槽滩微相发育在主槽侧缘槽两侧,漫洪带发育在工区西部。研究分析认为沉积微相的空间展布对油、水运动具有明显的控制作用,研究结果可以为工区目的层下一步勘探开发提供依据。on the bases of petrology ,log facies for the upper Kelamayi formation in the well 26-35 area of Xiazijie oilfield ,by the combination of principles and approaches of sedimentology and petrology ,and its sedimentary models were figured out in this paper .The top fan subfacies of the proluvial fan is the dominant facies for the target formation ,among them ,the major microfacies are the side edge of trough microfacies and the major trough microfacies ,and they tend to distribute in huge area with flakiness shape ,the slot beach microfacies distribute along two sides of major trough microfacies ,fluvial zone distribute the west area .The research results demonstrated that the spatial distribution of the depositional microfacies will mainly and obviously control the oil and water movement ,and it will provide a guideline for the further exploration and development .
