摘要
对东濮凹陷濮城油田沙三中亚段开展沉积微相研究,在水下扇沉积中识别出沟道、沟道间、席状砂、深湖—半深湖等微相。依据建立的主要微相测井相模式识别和划分单井相,结合砂岩含量及分布,绘制了沙三中亚段的沉积微相平面图。根据对研究区砂体展布和微相特征的预测,认为研究区南缘有另一个物源,在濮67南块可能分布有分流水道和水道间等较有利的沉积微相区,存在较好的砂体;西侧濮138块尽管砂层薄、层数少。但沙三中亚段存在较好的水下河道砂体,且席状砂体较为发育。据此制定了滚动勘探目标,钻探结果证实这两个区块的含油前景良好。
The middle interval of S_3 in the Pucheng oil and gas field, Dongpu Depression, is of sub-fan deposits. The distributary channel, sheet-like sand, intra channel sand and lacustrine mud could be determined according to the core and well-log analyses. Based on the sand-body distribution, the micro-facies model is established and the sand distribution outside the area controlled by the well could be predicted. Based on the distribution, some progressive exploration targets could be provided. All the drilled well got good oil production in this area, suggesting both blocks have potential for playing.
