珠江口盆地番禺地区珠江组层序地层特征
|
摘要
综合利用钻井、测井、地震资料,运用层序地层学原理,根据地震反射终止关系、钻测井上界面识别和井震结合,在珠江口盆地番禺低隆起珠江组共识别出1个二级层序界面,5个三级层序界面,划分为5个三级层序。在层序地层等时格架建立的基础上,探讨了层序的主控因素,认为珠江口盆地番禺低隆起珠江组层序地层主要受控于海平面变化和构造沉降,低位体系域易形成良好的岩性圈闭,是本区有利的勘探目标。
One second-order sequence boundary and five third-order sequence boundaries have been identified in the Zhujiang formation in the Panyu low uplift of the Pearl River Mouth Basin based on drilling,logging and seismic data according to seismic reflection termination relationship,drilling and logging identification of the boundaries.Based on the establishment of isochronal stratigraphic framework,the main control factors have been discussed.It is believed that the Zhujiang formation in the Panyu low uplift of the Pearl River Mouth Basin was mainly dominated by eustatic sea level change and tectonic subsidence;the lowstand system tract tends to form good lithologic traps,which are favorable exploration targets in the study area.
