摘要:
通过对露头及岩心的观察和研究后发现,准噶尔盆地四棵树凹陷古近系主要接受来自北部扎伊尔山以及南部依林黑比尔根山两大物源体系的供给。发育的沉积相类型多样:紫泥泉子组沉积时期广泛发育滨浅湖亚相,仅在凹陷北部发育小型扇三角洲扇群,在南部山前带发育冲积扇相、辫状河流相以及辫状河三角洲相; 安集海河组沉积时期古气候由干旱转湿润,受湖盆扩张的影响,在凹陷北部继承性发育退积型扇三角洲,而南部山前带仅发育辫状河三角洲相,凹陷中央在XH1井—T1井一线开始出现半深湖亚相。本文明确了四棵树凹陷古近系不同物源沉积体系的展布及演化规律,对该地区有利勘探方向的优选具有一定的借鉴意义。
Abstract:
According to the observation and study of outcrops and cores, it was found that the Paleogene in Sikeshu Sag, Junggar Basin, mainly received supplies from Zaire Mountain in the north of the sag and Eren Habirga Mountain in the south of the sag. The sedimentary facies in this area are various. Shore-shallow lake subfacies are widely developed in the sedimentary period of the Ziniquanzi Formation, while small fan delta group is only developed in the north of the Sag, and alluvial fan facies, braided fluvial facies and braided river delta facies are developed in the southern piedmont zone. The paleoclimate changed from drought to wet in the sedimentary period of Anjihaihe Formation which led to the expansion of the lake basin. So retrogradation type fan deltas are developed inherently in the northern of the sag, and braided river delta facies are only developed in the southern piedmont zone. Semi-deep lacustrine subface began to appear in the area between well XH1 to well T1.In this study, the distribution and evolution of sedimentary systems of the Paleogene in Sikeshu Sag have been clarified. The results provide some reference for the optimal selection of favorable exploration direction in this area.
