摘要： 通过对库车坳陷吐格尔明地区和克孜勒努尔地区的下侏罗统阿合组和阳霞组不同沉积微相(辫状河道、水下分流河道、心滩和河口坝)储集层微观非均质性特征的研究,认为不同沉积微相具有明显不同的岩石结构和孔隙结构;辫状河道微相储集性最好,其次为水下分流河道微相,心滩和河口坝微相最差;就相同微相而言,吐格尔明地区要优于克孜勒努尔地区。

Abstract: This paper analyzed the micro-heterogeneous features of different sedimentary microfacies (braided channel,underwater distributary channel, channel bar and debouch bar) of A he formation and Yangxia formation in Tugermin area and Kezilenur area of Kuche depression. The result showed that different sedimentary microfacies possess clearly different rock structures and pore configurations; the braided channel microfacies are of the best reservoir quality,underwater distributary channel microfacies are of average quality,while channel bar and debouch bar of the poorest. F or the same microfacies, that of Tugermin area is better than that of Kezilenur area.

Key words: Tarim basin, Kuqa Depression, Early Jurassic, sedimentary microfacies, reservoir, microstructure, heterogeneity
