摘要

根据陆相层序在地震剖面及电测曲线上的识别标志 ,采用沉积旋回分析技术及Fis cher图解法 ,将泌阳断陷双河—赵凹地区下第三系核三上段划分为 3个陆相层序 ,在研究区表现为冲积扇 -扇三角洲 -湖相沉积体系空间配置关系。在这三个陆相层序中发育低位加积型、退积型、高位加积型和进积型四类小层序组共 1 3个 ,其中可识别的小层序达 4 0余个 ,并进一步阐明了其沉积相 (微相 )构型特征。
According to discrimination marker of terrigenous sequence on seimic profiles and well-logging,and using the methods of sedimentary cychicity analysis and Fischer diagram,the upper member of Eh 3 of Shuanghe-Zhaoao in Biyang fault-depression can be classified into three terrigenous sequences. In the studied area,there lies fluvial fan-fan delta-lacustrine deposinal system sequencely.In the three terrigenous sequeces,there are well-developed thirteen parasequences of four basic types:lowstand aggradation and regression,highstand aggradation and progradation.Among them there are more than forty recognizable parasequences.The sedimentary facies land microfacies have been further explainded in this paper.
