| 摘 要： | 通过岩石类型、粒度分析、沉积构造特征、测井相分析,并结合区域地质背景,认为西峰油田董志区属于辫状河三角洲前缘沉积,共识别出水下分流河道、水下天然堤、残余河口坝、分流间湾等4个沉积微相类型,其中水下分流河道微相是长81储层的主要沉积微相。水下分流河道自西南向东北方向延伸,主要呈现四个水下分支河道。 |
| 关 键 词： | 沉积微相 董志区 西峰油田 |

| Abstract: | Through rock types,grain size analysis,sedimentary structural features and electrofacies analysis,combining with regional geological setting,we consider that Dongzhi region in Xifeng Oilfield attributes braided delta front sedimentation.We recognite four sedimentary microfacies types of underwater distributary channels,subsea natural levees,residual mouth bars and interdistributary bays.And underwater distributary channels are mainly sedimentary microfacies of Chang 81 reservoir.The underwater distributary channels extend from southwest to northeast,and mostly present four underwater branch channels. |
| Keywords: | sedimentary microfacies Dongzhi region Xifeng Oilfield |
