| 摘 要： | 通过对研究区内岩心的岩石相特征、沉积构造、录井资料以及电测曲线的综合认识,结合连井地层的对比,对麻黄山西区块长62小层的沉积相类型以及砂体展布特征进行了系统的研究:认为长62小层为三角洲前缘沉积,识别出5中沉积微相;其中水下分流河道和河口坝微相是研究区储集砂体的主要沉积类型,并确定了长62油层组沉积微相的平面展布,为储层有利区块预测奠定了基础。

| Abstract: | By comprehensive understanding of the rock core,sedimentary structures and logging in study area,the sedimentary faces and distributional characteristics were analyzed.The Chang 62 formation developing front of delta and 5 kinds of sedimentary microfaces were identified.The results showed that underwater distributaries channel and mouth bar which can be as exploration target area were the main types of reservoir. |
