四川盆地包界地区须家河组层序界面特征
|
摘要
层序地层学研究最关键的是对层序界面的识别。以四川盆地包界地区须家河组为例,综合应用野外露头、钻井岩芯、测井曲线、地震剖面等资料,识别出4种类型的层序界面,它们分别是:冲刷面、岩性岩相转换面、古风化壳、沉积结构转换面。并阐述了研究区层序界面在钻井岩芯、野外露头、测井曲线、地震剖面上的特征、识别标志和表现形式。这一研究成果对于正确划分研究区须家河组层序具有重要意义。
It is well known that the identification of sequence boundaries is the key to sequence stratigraphic research.Using the Xujiahe Formation in the Baojie Area of Sichuan Basin as an example,we recognized four types of sequence boundary on the basis of outcrop,drillcore,logging,and seismic.These different types of sequence boundary are represented by erosion surfaces,sedimentary facies changes,weathering crusts and sedimentary structure changes.Their characteristics,drill cores,outcrops,logging curves,and seismic sections are described in detail in this paper.
