松辽盆地中央坳陷区头台油田扶余油层高分辨率层序地层学研究
|
摘要
以松辽盆地头台油田扶余油层为研究对象,对研究区42口取芯井的分析,利用高分辨率层序地层原理,结合岩性、电性资料,进行层序地层的划分,识别该地区短期基准面旋回类型,建立层序地层格架并分析沉积相类型及展布。得出该地区发育浅水三角洲沉积和湖泊相沉积,进而识别出其多种沉积微相类型。扶余油层泉四段发育两种短期基准面旋回类型,并细分出6种亚类。划分出Q4MSC1~Q4MSC3三个四级层序,Q4SSC1~Q4SSC7七个五级层序,并建立层序地层格架,绘制细分层单元沉积微相图,为寻找有利砂体展布提供预测。
Taking the Fuyu oil field in Songliao Basin as the research object,analysis of 42 core wells in the study area,take the principle of high resolution sequence stratigraphy into account,and the sequence stratigraphy is divided according to lithology and electrical data,the short-term base level cycle is identified,the sequence stratigraphic framework is established,and the types and distribution of sedimentary facies are analyzed.It is concluded that the shallow water delta and lacustrine sediments are developed in this area,and various types of sedimentary microfacies are identified.There are two types of short-term base level cycles in the Quan Formation forth segment of the Fuyu oil reservoir,and the short-tern subdivided into 6 subclasses.The research area can be classified into 3 forth order sequences Q4 MSC1 ~ Q4 MSC3 and 7 fifth-order sequences Q4 MSC1 ~ Q4 MSC7 and establish sequence stratigraphic framework.Draw a diagram about subdivision of sedimentary microfacies to make a prediction of favorable sand body distribution.
