松辽盆地裕民地区北部泉头组四段沉积特征
|
摘要
以松辽盆地裕民地区泉头组四段为研究对象,利用高分辨率层序地层学原理并结合测井、岩性资料,识别该地区的层序界面并进行层序地层的划分,建立层序地层格架,分析沉积相类型及展布.结果表明,该地区泉四段可划分为3个中期旋回、7个短期旋回,发育曲流河相和浅水三角洲相,识别出河漫、河床、三角洲平原、三角洲前缘4个沉积亚相及多种沉积微相.通过沉积相类型、岩性组合特征、沉积相平面展布以及垂向变化分析,绘制细分层单元沉积微相图件,为寻找有利砂体提供预测.
To study the fourth member of Quantou Formation(Q4) in Yumin area,Songliao Basin,the principle of high-resolution sequence stratigraphy is combined with well logging and lithologic data to identify the sequence boundary and divide the stratathen establish the sequence stratigraphic frameworkand finally analyze the sedimentary facies and distribution.The result indicates that Q4 can be divided into three mid-term cycles and seven short-term cycles,with development of meandering river and shallow delta facies,from which four sedimentary subfacies of river flood,riverbed,delta plain and delta front,and various microfacies can be identified.Based on the analysis of sedimentary facies types,lithologic association,plane distribution and vertical variation of sedimentary facies,the sedimentary microfacies maps of subdivision layers are drawn,which can provide prediction for prospecting favorable sand body.
