准噶尔盆地滴南凸起水西沟群层序地层特征
|
摘要
基于Vail经典层序地层学理论,综合运用地质、测井和地震资料,对准噶尔盆地滴南凸起水西沟群的层序地层特征及勘探潜力进行了研究。根据地震、钻井及测井资料显示的界面特征,识别出5个层序界面、4个初始湖泛面、4个最大湖泛面,据此将研究区侏罗系水西沟群划分为JSQ1、JSQ2、JSQ3J、SQ4 4个三级层序,12个体系域。对各三级层序特征进行了分析,建立了水西沟群八道湾组和三工河组沉积体系分布格架和地层层序模式。据八道湾组一段及三工河组二段一砂层组沉积相平面展布特征及油气显示情况,认为这两个层段油气勘探潜力巨大,勘探的主要方向为与辫状河道砂体有关的岩性圈闭和低幅度背斜圈闭。
On the basis of Vail's classical sequence stratigraphy theory,this paper studied the sequence stratigraphy and exploratory potentiality in the Dinan area of Junggar Basin using the geologic,logging and seismic data.According to the interface characteristics revealed by the seismic,drilling and logging data,it recognized five sequence boundaries,four initial flooding surfaces,four maximum flooding surfaces,and Shuixigou Group was divided into four 3rd-order sequences(JSQ1,JSQ2,JSQ3,JSQ4) and twelve systems tracts.It analyzed the sequence characteristics of every sequence,and established sequence stratigraphic frameworks and models for J1b and J1s.According to sedimentary facies and oil/gas shows in J1b1 and J1s21,these two formations have huge exploratory potentiality.Exploratory direction is to look for lithologic traps and low-amplitude anticline traps related to braided channel sands.
