断陷和坳陷盆地富有机质泥岩测试参数及研究意义

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。

Testing parameters of organic-rich mudstone in faulted basin and depressed basin and their significance

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 lowtemperature 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．
