摘要
准噶尔盆地卡因迪克地区侏罗系是重要的勘探层位之一,本次研究从该区单井划相出发,详细研究了其侏罗系沉积相区域展布特征,提出物源主要来自北面的车排子凸起,边缘相不发育,主要为三角洲-湖泊沉积体系。在此基础上分析了其沉积体系的演化过程,根据层厚度变化确定了四棵树凹陷自侏罗纪以来沉降中心的迁移,最后预测出砂体展布范围并指出了有利储层分布。
The Jurassic System at Kayindike area is one of important exploration targets in Junggar Basin.Based on the analysis on facies of individual well,the distributions of regional sedimentary facies in Jurassic were studied in detail.Study shows that the source mainly comes from Chepaizi uplift with scarce edge facies but the ample delta and lake sedimentary systems.Consequently,the evolutional process of sedimentary system was analyzed.Study on sequence thicknesses suggests that the transferring of subsidence centers in Sikeshu depression is determined.Finally,the sand body range is predicted and the favorable reservoir is presented.
