| 摘 要： | 利用区域地质、地震、测井及岩心分析资料,对濮城油田南区沙二上4-7砂岩组储层的沉积特征进行了全面研究。结果表明,4-7砂岩组为小型闭塞陆相断陷湖盆三角洲前缘沉积,成分和结构成熟度低,可进一步划分为7种微相类型;建立了三角洲前缘砂体的垂向相序和演化模式,总结了储层的平面微相展布规律,为油气勘探开发指明了方向。 |

| Abstract: | The reservoir sedimentary characteristics of the No.4-7 sand sets in the upper of the 2~(nd) member of the Shahejie Formation in southern Pucheng oilfield were fully studied in terms of regional geology,seismic,well log as well as core analysis.The result indicates that the 4-7 sand sets belong to a kind of delta front deposition developed in a little occlusive non-marine fault-trough lake basin.The reservoir is of low compositional and textural maturity,and can be divided into 7 types of micro-facies.Meanwhile,the vertical sequence and the evolution models of the delta front sand-bodies in this area are established. Furthermore,the lateral distributing regularities of the micro-facies are summarized. |
| Keywords: | front edge of delta reservoir micro-facies model facies sequence Pucheng oilfield |
