摘要

摘要: 根据高频旋回层序在长周期旋回层序内的有序叠加方式可在研究区石炭系中划分出3个Ⅲ级旋回层序和2个Ⅱ级旋回层序.其中Ⅲ₃和Ⅲ₃旋回层序为海侵体系域,Ⅲ₂为高水位体系域,它们共同构成了研究区的层序地层格架并且控制着沉积相和生储盖组合的时空展布特征.由于受成岩历史差异性和不同成岩环境的影响,石炭系碎屑岩和碳酸盐岩储集岩成岩特征和储集性能在巴楚隆起区和麦盖提斜坡区均存在明显差异,且分布在斜坡区的储层物性明显优于隆起区同层位的储层,是近期有利的的勘探区域.

Abstract: According to the ordered superimposed styles of high frequency cyclic sequences within long period cyclic sequences,three Ⅲ order cyclic sequences and two Ⅱ order cyclic sequenes were divided in the Carboniferous of the study area.Among them,Ⅲ 1 and Ⅲ 3 cyclic sequences belong to the transgressive tract system,and Ⅲ 2 belongs to the highstand tract system.They constitute together the sequence stratigraphic framework of the study area and control the space time distributive characteristics of sedimentary facies and source rock reservoir cap rock assemblages.As affected by the differences of diagenetic history and different diagenetic environments,the diagenetic characteristics and storage peformances of the Carboniferous clastic and carbonate reservoir rocks have obvious differences between the Bachu Uplifting area and the Maigaiti Slope area.Besides,the reservoirs distributing in the slope area have obviously better physical properties than those in the same formations of the uplifting area,and are the favorable exploration targets in the near future.
