摘要：

以准噶尔盆地西北缘扎伊尔山出露的三叠系克拉玛依组黑油山沟35 剖面为例，利用岩相组合和层次界面分析方法，结合沉积学理论，探讨了砂砾质辫状河岩石相组合、构型界面及构型单元级次，进而研究砂砾质辫状河河道砂体内部隔夹层的成因、级次、形态、规模及其控制下的渗流地质差异特征。结果表明，在研究区可以识别8 种典型岩相，8 个5 级储集体构型单元以及2 个3 级储集体构型单元。泥质隔夹层主要分为细粒沉积和泥砾型两种类型，泥砾型隔夹层主要发育在河道底部泥砾岩沉积，由河道侵蚀河岸或河底的泥岩快速堆积而成，主要分布在5 级或3 级界面之上，向河道两侧边缘减薄尖灭。同时，内部不同级次的泥质隔夹层控制了储层非均质。

Abstract:

Based on Triassic Karamay Formation outcrop of 35 profiles in Heiyoushan，which is located in the Zaire Mountain， northwestern of Junggar Basin. The lithofacies associations，architecture boundaries and hierarchy of architecture units are discussed by using lithofacies associations and hierarchy interface analysis methods，combined with sedimentary theory. Then， the origin，hierarchy，morphology as well as scale of intercalation in the sand-gravel braided river are analyzed. The results show that eight typical lithofacies which can be divided into eight fifth hierarchy architecture units and two third hierarchy architecture units are recognized. While the muddy intercalation is mainly divided into fine type and mud boulder type. Different level architecture units were identified in the fine grained type deposits. The mud boulder type intercalation chiefly develops in the bottom of channel，formed by the rapid sediment of mud which was caused by the erosion of bank and river bottom. It principally distributes on fifth or third hierarchy surface，pinching out toward both sides of channel. At the same time，internal intercalation of the different hierarchy controlled reservoir heterogeneity.

Key words: sand-gravel braided river, outcrop, intercalation, Karamay Formation, northwestern margin of Junggar Basin
