摘要：通过对长武—富县地区钻井和露头长 73 亚段开展岩性描述、薄片鉴定、X--射线衍射等分析，识别出 5 种主要泥页岩岩性类型，分别为黏土质页岩、含凝灰黏土质页岩、凝灰质黏土质页岩、含粉砂黏土质泥岩和粉砂质黏土质泥岩; 同时识别出 3 种主要夹层岩性类型，分别为细砂岩、凝灰岩和沉凝灰岩。在统计分析基础之上，划分了 4 种主要岩性组合类型，即纯泥页岩型、泥页岩夹砂岩型、泥页岩夹凝灰岩型、泥页岩夹砂岩和凝灰岩型，并明确了不同类型岩性组合的分布特点。对黏土质页岩和含粉砂黏土质泥岩 2 种主要泥页岩类型开展生烃特征评价，认为 2 种泥页岩的有机质丰度和热成熟度均达到了页岩油形成的标准，含油性指标也显示其达到了页岩油资源富集级别。储层物性特征评价认为，相对于泥页岩，细砂岩和凝灰岩类夹层具有更优的物性条件，因此夹层发育对于提高泥页岩层段整体物性条件具有积极作用，且细砂岩夹层起到的积极作用更大。勘探有利区评价认为，研究区泥页岩一类有利区主要分布在张村驿—张家湾、上畛子林场、安置农场等地区，其中张村驿泥页岩夹砂岩型岩性组合发育区为最有利勘探目标，其次为上畛子林场、安置农场泥页岩夹凝灰岩型勘探目标，以及张家湾纯泥页岩型勘探目标。

Abstract: Through lithology description，thin section identification and X--ray diffraction analysis of drillings and outcrops of the Chang 73 sub-member in Changwu--Fuxian area，five main shale lithology types are identified， namely clay shale，tuff-bearing clay shale，tuffaceous clay shale，silt-bearing clay mudstone and silty clay mud-stone． At the same time，three main interlayer lithology types are identified，namely fine sandstone，tuff and sedimentary tuff． On the basis of statistical analysis，four main types of lithologic assemblages are divided，namely pure shale type，shale with sandstone type，shale with tuff type，shale with sandstone and tuff type，and the distribution characteristics of different types of lithologic assemblages are defined． The hydrocarbon generation characteristics of clay shale and silt-bearing clay mudstone are evaluated． It is considered that the organic matter abundance and thermal maturity of the two kinds of shale meet the standard of shale oil formation，and the oil-bearing index also shows that they have reached the enrichment level of shale oil resources． According to the evaluation of reservoir physical property characteristics，compared with shale，fine sandstone and tuff interlayer have better physical property conditions． Therefore，interlayer development plays a positive role in improving the overall physical property conditions of shale section，and fine sandstone interlayer plays a greater positive role． According to the evaluation of favorable exploration areas，the first-class favorable areas of shale in the study region are mainly distributed in Zhangcunyi--Zhangjiawan，Shangzhenzi forest farm，Anzhi farm and other areas． Among them，the development area of shale with sandstone type in Zhangcunyi is the most favorable exploration target，followed by the exploration target of shale with tuff type in Shangzhenzi forest farm and Anzhi farm，as well as the exploration target of pure shale type in Zhangjiawan．

Keywords: shale oil lithologic assemblages favorable area evaluation Chang 73 sub-member Changwu-- Fuxian area Ordos Basin
