巴楚隆起井下寒武系发育齐全,划分为3统7段,自下而上为下统碎屑岩段、白云岩段、下含膏白云岩段,中统盐下碳酸盐岩段、膏盐岩段、上含膏白云岩段与上统纯白云岩段,各段之间电性特征明显。在碎屑岩段获丰富的小壳与藻类化石,详细地讨论了小壳化石的时空分布,确定巴楚隆起井下含小壳化石地层的时代为早寒武世早期,并与地表露头剖面进行了对比,认为碎屑岩段与玉尔吐斯组上部为同时异相关系,盐下碳酸盐岩段对应于沙依里克组,并作为区域地层对比标志层。地震层序地层可将寒武系划分为3个超层序,分别对应与3个统;钻井层序地层可划分为2个半超层序、5个层序。该区寒武系的划分与对比为其它学科进一步研究奠定了坚实的地层学基础。
Bachu uplift underground Cambrian developed well, is divided into 3 System 7, bottom-up clastic rocks, dolomite, under the creamy dolomite, salt under the Central Plains carbonate, Gypsum salt rock, dolomite on the paste and the upper pure dolomite, the electrical characteristics of the various segments is obvious. The rich shell and algae fossils in the clastic rocks have been discussed. The temporal and spatial distribution of the small shell fossils has been discussed in detail. The time of determining the small shell fossil formations in the Bachu uplift is the early Early Cambrian and is associated with the surface profile In contrast, it is considered that the upper part of the clastic rocks and the Yurtuisu Formation are simultaneously heterogeneous, and the lower carbonate rocks correspond to the Shayiruk Formation and serve as a contrast marker layer in the regional strata. Seismic sequence stratigraphy can be divided into three super-sequence Cambrian, respectively, corresponding to 3 systems; drilling sequence stratigraphy can be divided into two half-super-sequence, five sequences. The division and contrast of the Cambrian in this area has laid a solid foundation for further study of other disciplines.
