Abstract

Abstract: Tar-rich coal resources are widely distributed in Xinjiang region, from which oil and gas can be extracted through low-temperature pyrolysis. However, there is a great difference in the pyrolytic tar yield at different sedimentary locations, restricting the fine exploration and evaluation of tar-rich coal. This paper is a case study of coal samples extracted from Badaowan Formation and Xishanyao Formation in Santanghu Basin. Based on fully understanding of the aliphatic chain structure in the form of methylene and methyne as a key microscopic characteristic for tar-rich coals, the paper illustrates the molecular structural features of coal macerals and the effect of coal macerals on tar yield, and reveals the control law of peat bog environment on the coal molecular structure and tar yield. The results indicate that more long-chain aliphatic structures of vitrinites can help increase coal tar yield, and the tar-rich coal formed in the peat bog environment characterized by high water levels, strong reducing conditions and high-degree plant tissue degradation contains more aliphatic hydrogen structures, especially methylene and methyne structures, thus producing high-yield pyrolytic tar. The coal in Badaowan Formation processes the above characteristics of key substances and a coal-forming environment so that it has a higher tar yield than that in Xishanyao Formation. Meanwhile, plant types at different coal-forming stages and differences in their responses to the thermal evolution of paleotemperature are also worth discussing.

Key words: tar-rich coal, molecular structure, maceral, coal-forming environment, Santanghu Basin

摘要： 新疆地区广泛分布通过低温热解提取油气的富油煤资源,但其在不同沉积位置的热解焦油产率存在较大差异,制约了富油煤精细勘查评价。以三塘湖盆地八道湾组和西山窑组煤样为研究对象,在充分认识以亚甲基、次甲基等形式存在的脂肪链结构是富油煤关键微观特点的基础上,阐释了煤显微组分的微观分子结构特点及其对焦油产率的影响,揭示了泥炭沼泽环境对煤分子结构及其焦油产率的控制规律。研究结果表明:镜质组的长链脂肪结构更加丰富有利于提高煤焦油产率,覆水较深、还原性强、植物组织结构降解程度高的泥炭沼泽环境形成的富油煤包含更多的脂肪氢结构,尤其是亚甲基和次甲基结构等,从而产出更高的热解焦油。八道湾组煤具备上述关键物质特点及成煤环境特点,从而比西山窑组煤具有更高的焦油产率。同时,不同成煤期植物类型及其对古地温的热演化响应差异也是值得探讨的问题。
