摘　　要：利用岩芯、录井和测井等基础资料,对子长地区长6储层沉积相演化特征进行研究,分析油水层的分布规律及控制油水分布的主控因素。研究结果表明,控制研究区油水层分布的因素较多,但主要受沉积相、优质储层、鼻状隆起构造、区域盖层、运移通道等因素的控制。其中,沉积微相砂体展布特征、储层物性及鼻状隆起是制约油水分布的主要原因。Based on fundamental data of the core,log and well logging,the article studies the sedimentary microfacies types and evolutionary feature of Chang 6 in Zichang area and analyzes the distribution regular pattern of the oil and main controlling factors of Water distribution.The result shows that there are many factors to control distribution of oil and water layers in the studied area and mainly controlled by some factors such as sedimentary facies,high-quality reservoir,the nose-uplift structure,the regional seal,migration channel and others.Among them,the characteristics of the sedimentary microfacies sand body distribution,reservoir properties and the nose uplift is the main reason for restricting water distribution.
