在阐述了煤成油的概念,总结和评述了煤生油显微组分、生油门限、生油范围和生油高峰等问题后,本文通过吐哈等盆地侏罗系煤生油显微组分组成特征、可溶有机质演化、成熟度和有机质丰度、油源(岩)及原油成熟度对比;含煤岩系中煤层和泥岩的厚度及总量和煤及泥岩最高沥青和总烃转化率的对比;煤及其族组成和煤成原油的族组成特征的对比;提出了中国侏罗系煤成油盆地中泥岩比煤层对煤成油田形成有更大的贡献的看法。
After elaborating the concept of coal-to-oil and summarizing and commenting on the issues such as the microscopic composition of coal-derived oil, the oil-generating threshold, the oil-producing range and the peak of crude oil production, Composition of components, evolution of soluble organic matter, maturity and abundance of organic matter, oil source (rock) and crude oil maturity; thickness and total amount of coal seam and mudstone in coal-bearing rock series and maximum bitumen and total hydrocarbon of coal and mudstone Comparison of conversion rates; Comparison of coal and its ethnic composition with that of coal-derived crude oil; Proposed that the middle mudstone in the Jurassic coal-forming basin of China has a greater contribution than the coal seam to the formation of coal-formed oil fields.
