1前言在阿塞拜疆东部和土库曼斯坦西部晚第三纪三角洲储层中，油气储量十分丰富（图1略）。通过对阿塞拜疆境内露头储层沉积记录的分析，4种从冲积网状河砂岩和砾岩到三角洲前缘粉砂岩和泥岩的沉积相组合已经确定出来，它们分别代表一系列不同的古环境条件。4种沉积相组合显示 1 Introduction Reservoirs are abundant in the Late Triassic delta in eastern Azerbaijan and western Turkmenistan (Figure 1 omitted). Based on the analysis of sedimentary records of outcrops in Azerbaijan, four sedimentary assemblages of alluvial reticular sandstone and conglomerate to delta front siltstone and mudstone have been identified, each representing a series of different paleo-environmental conditions. Four sedimentary facies combinations show
