摘　　要：通过对姬塬油田元214区块长61油层岩心观察,结合岩石类型、沉积构造、测井相等相标志对该区进行了沉积相特征研究,指出元214区长61油层沉积相大致呈北东-南西向展布,沉积相类型主要为三角洲沉积相三角洲前缘亚相,主要发育水下分流河道微相,分流间湾微相,偶有河口坝微相发育。其中水下分流河道砂体是长61储集层的骨架砂体,并确定了长61油层沉积微相的平面展布,为储层有利区块预测奠定了基础。Based on core observation and analysis of rock types,sedimentary structure and logging facies,sedimentary facies characteristics were studied.The results show that sedimentary facies of Chang 61 reservoir in Yuan 214 area distributes from northeast to southwest.The sedimentary type is mainly deltaic deposit and delta-front facies.Main development is underwater distributary channel microfacies,interdistributary bay microfacies and a spot of river mouth bar microfacies.Underwater distributary channel is the sand body framework of Chang 61reservoir.And plane distribution of Chang 61reservoir sedimentary microfacies has been determined,which can lay a foundation for predicting favorable reservoir blocks.
