摘　　要：以松辽盆地和桦甸盆地为例,对盆地中富有机质泥岩进行系统测试。分析表明,富有机质泥岩中含油率和TOC、气体损失率呈明显的正相关;而与半焦、密度呈负相关;与全水的相关性不明显。结合相关研究表明,松辽盆地富有机质泥岩中有机质主要来自湖泊自身生产物,沉积速率较慢,且成岩作用相对较强,此盆地油页岩适合低温干馏炼油,因干馏后半焦中残留有机质较少,适合烧砖、制作水泥等。桦甸盆地油页岩有机质为湖泊生物和陆源有机质共同来源,沉积速率相对较快,成岩作用较弱,此盆地油页岩适合低温干馏炼油,干馏后半焦中残留有机质较多,适合发电和烧砖等,损失气体可以回收进行瓦斯发电。We test organic-rich mudstone systematically in Songliao Basin and Huadian Basin.The analysis of organic-rich mudstone indicates that oil rate is significantly positively correlated to TOC and gas loss rate,while negatively correlated to simi-coke and density.It is not significant to relate with water.A series analysis of test indicators indicated that organic matter of that organic-rich mudstone in Songliao Basin is mainly from the lake＇s own production.Deposition rate is low,and diagenesis is relatively strong.Oil shale from Songliao Basin utilize low-temperature carbonization to refine shale oil.Since residual organic matter is less,the semi-coke is only properly appied for baking bricks and producing cements.Organic matter of that organic-rich mudstone in Huadian Basin is from lake organism and terrestrial organic matter,deposition rate is relatively high,and diagenesis is weak.Oil shale from this basin is utilized low-temperature carbonization to refine shale oil.As residual organic matter is more,the semi-coke is suitable for power generation and brick making,and the gas can be recycled for power generation.
