河流相砂体是含油气盆地中重要的储油层系。本文以济阳坳陷埕东北坡馆陶组河流相砂岩为例,详细总结河流相砂岩的储集空间类型,对研究区不同砂层组内河流相沉积砂体及不同沉积微相内砂体储层物性参数的变化进行统计分析,确立河流相沉积中不同微相内的砂体储集性,并探讨沉积岩岩性、沉积微相及成岩作用等因素对河流相砂岩储层发育的控制作用。
River sand body is an important oil-bearing basin reservoir system. Taking the sedimentary facies sandstone of Guantao Formation in northeastern slope of Jiuyang depression in Jiyang depression as an example, this paper summarizes the reservoir space types of fluvial facies sandstone in detail and analyzes the relationship between the fluvial sedimentary sand bodies in different sand layers of the study area and the sand bodies in different sedimentary microfacies Reservoir physical properties of the changes in the statistical analysis to establish river sediment deposition in different microfacies and to discuss sedimentary rock lithology, sedimentary microfacies and diagenesis and other factors on the development of fluvial sandstone reservoir control .
