| 摘 要： | 曙266断块油藏杜家台油层为扇三角洲前缘沉积。本次研究精细划分出水下分流河道、水下分流间湾、水下天然堤、河口坝、远砂坝、前缘席状砂及前三角洲泥7个沉积微相，其中水下分流河道是本区储层的主要成因类型。平面上，杜家台油层属强非均质性，储层层内及层间属中等一强非均质性，在微观上则表现为细喉道、高配位数的特点。本区储层非均质性主要受沉积环境的控制。

| Abstract: | The Dujiatai pay zone of the Shu266 fault block reservoir consists of fan-delta front deposits,which may be divided into seven microfacies: subaqueous distributary channel,subaqueous interdistributary embayment,mouth-bar,distal-bar,front sheet sand and prodelta mud,of which subaqueous distributary channel sands are the main genetic type of reservoir in the area.In a plan view,the Dujiatai pay zone is highly heterogeneous,while the inter-reservoir and within-reservoir heterogeneities are moderate-high.Microscopically,it is characterized by high coordination numbers and thin throats.The reservoir heterogeneity in the area is mainly controlled by the sedimentary environment. |
