| 摘 要： | 准噶尔盆地吉木萨尔凹陷芦草沟组为一套优质陆相烃源岩, 是我国当前页岩油气研究的热点地区之一.基于吉木萨尔凹陷18口井芦草沟组约为580 m岩心观察、薄片观察、地球化学测试等数据, 对芦草沟组烃源岩岩石类型、地球化学特征等方面开展了研究与评价, 结果表明: 1)芦草沟组烃源岩整体上为优质烃源岩, 且以Ⅰ-Ⅱ型有机质类型为主, 处于低熟至成熟阶段; 2)烃源岩主要划分为5种类型, 包括纯页岩、白云质页岩、纯泥岩, 白云质泥岩和粉砂质泥岩, 其有机质类型和丰度存在一定差异.综合研究得出, 吉木萨尔凹陷芦草沟组优质有效烃源岩的有机质丰度下限值为2.0%, 并认为TOC≥2.0%的烃源岩段也是该区页岩油发育的有利层段.

| Abstract: | The source rocks of Lucaogou Formation in Jimusar sag, Junggar Basin is a set of excellent continental hydrocarbon source rock, and is also one of the hotspots of the shale oil and gas research in China. On the basis the examination of 580 meters of 18 well cores, observation of thin sections and organic geochemistry analysis, the rocks types and organic geochemistry characteristics of the source rocks were comprehensively studied. The results reflected that: 1)On the whole, the hydrocarbon source rocks of the Lucaogou Formation were high quality source rock, whose kerogen were mainly Ⅰ~Ⅱ types, and were at the stage of low maturity to maturity; 2)The source rocks could mainly be classified into five rock types: pure shale, dolomitic shale, pure mudstone, dolomitic mudstone and silty mudstone. Through comprehensive study, the organic carbon content limit value of the high quality and effective source rock of the Lucaogou Formation hydrocarbon source rocks was 2.0%. Meanwhile, the hydrocarbon source rocks with TOC≥2.0% were also the favorable layers for shale oil in the Jimusar sag. |
