摘要
利用层序地层学的原理和方法，系统分析了塔里木盆地巴楚凸起南部玛扎塔格构造带石炭系的岩心、测井和地震资料，将石炭系划分为三个层序（１个Ⅰ型层序、２个Ⅱ型层序）和８个体系域，该层系体系域类型齐全。石炭系包括三套天然气储集层，分别对应于低水位体系域、陆棚边缘体系域和并进型高水位体系域，对比研究认为体系域对储集层的储集性能和空间展布有较好的控制作用。
According to the principle and method of sequence stratigraphy, this paper
systematically analyzed the core, well logging and seismic data of Carboniferous in Mazartag
structural belt in southern Bachu arch of Tarim basin, dividing the Carboniferous into three
sequence (one type, and two type sequences) and eight system tracts, which includes three
sets of gas reservoirs corresponding to lowstand system tract, shelf margin system tract and
keepingup highstand system tract. Comparison results showed that the system tracts have a
better control on storage feature and space distribution of reservoir, keepingup highstand
system tract should be the most favorable exploration area.
