为明确辽河西部凹陷曙一区杜84块兴Ⅰ组油层成藏规律及下一步剩余油挖潜方向,综合运用岩心、测井资料系统分析了研究区的油层分布特征及控藏因素。结果表明:兴Ⅰ组油层主要分布于XⅠ1—2及XⅠ2—1小层内,为典型的边水油藏;兴Ⅰ组空间上受构造高部位、断层及不整合面的综合控制,平面上受沉积微相及储层岩性差异的双重制约。
In order to clarify the reservoir formation law and the direction of the remaining oil tapping potential in Block Du 84 Block Xingshu of Lühe West Depression, the oil and gas reservoir distribution characteristics and reservoir holding factors in the study area were analyzed synthetically using core and well logging data. The results show that the oil layer of Xing Ⅰ Formation is mainly distributed in the small layers of XⅠ1-2 and XⅠ2-1, which is a typical edge water reservoir. The composition of Xing Ⅰ Formation is controlled synthetically by the high positions, faults and unconformities in the space. Affected by sedimentary microfacies and reservoir lithology double constraints.
