摘　　要：高邮凹陷HJ油田是一个受岩性-构造控制的复杂断块油气藏,古近系戴南组沉积时期发育了扇三角洲平原和扇三角洲前缘沉积,主要发育辫状河道、辫状河道间、水下辫状河道、水下辫状河道间、河口砂坝等微相。该区戴南组储集层物性主要受控于沉积相带、粒度、碳酸盐胶结等因素;水下分流河道储层物性良好,扇中辫状河道、河口砂坝储层物性较差;碳酸盐胶结物含量对储层物性起破坏作用;相同成岩带内岩石粒度与孔隙度、渗透率都有较好的正相关性。沉积微相与沉积物结构研究对戴南组油藏的勘探与开发具有重要的地质意义。HJ Oilfield in Gaoyou Depression was a complicated fault-block reservoir controlled by structure-lithology.Fan delta plain and fan delta front were developed in Dainan Formation(E2d),the main sedimentary micro-facies were braided channel,inter-braided channel,underwater braided channel,underwater inter-braided channel and channel mouth bar.The reservoir physical property of Dainan Formation was controlled by the factors of sedimentary facies zone,particle size and carbonate cementation.The reservoir physical property of underwater braided channel was better than braided channel and channel mouth bar.Carbonate cement content destroys the reservoir physical property.In the same diagenesis zone,there are positive correlations between rock grain size and porosity,permeability.The study of sedimentary micro-facies and sediment structure has important geological significance for reservoir exploration and development.
