【摘要】 本文综合运用地质、测井、地震和化验分析等资料,对济阳坳陷上第三系沉积特征进行了全面系统地研究,认为该时期发育冲积扇和河流2种沉积相类型,河流相可细分为4种亚相7种微相。通过单井和连井剖面相分析,研究了沉积相的演化规律,并编制出各时期的沉积相平面图,分析了物源区及古河流流向,指出了有利的油气储集相带。更多还原

【Abstract】 The authors have studied the sedimentary characteristics of the Neogene in the Jiyang depression using the geological,log,seismic and chemical analysis data. It is thought that in this period there developed two types of sedimentary facies, alluvial fan facies and river facies. The river facies is divided into 4 sub-facies and 7 microfacies. Through the facies analysis of single-well and multi-well sections. The authors have studied the change of the sedimentary faices,prepared maps of sedimentary facies in different periods,analyzed provenances and the flow direction of the ancient rivers and finally pointed out advantageous oil-gas reservoir facies zones.更多还原
