利用CiteSpace可视化软件,形成页岩油研究的国家/地区、机构、学科及共引文献知识图谱,揭示页岩油的研究力量、学科属性、研究热点及研究演进历程。研究表明,页岩油研究正处于快速发展阶段。美国在页岩油研究领域发挥关键作用。工程学领域和能源与燃料学是开展页岩油研究的主要学科阵地。油页岩热解是该领域持续性研究热点,围绕干馏技术、干馏因素分析、加氢催化热解等主题开展了相关研究。随着技术的进步,傅里叶变换离子回旋共振质谱(FT-ICR MS)等新技术分析油页岩的分子组成、油页岩微观孔隙以及蕴藏其中的非常规可采油气成为研究新热点。

With the help of visualization tool CiteSpace, this paper formed the knowledge mapping of the nations/areas, institutions, subjects and co-citation of shale oil studies, and displayed the research nations, subjects, research focuses and study history of shale oil. The study showed that shale oil study is undergoing a rapid development, with America playing the leading role. Engineering and energy and fuel study are the main research front. Destructive distillation of oil shale is the focus of related studies, with many studies concentrating on such topics as retorting techniques, retorting factors and catalytic hydropyrolysis and so on. With the development of technology, analyses of oil shale molecular component with new techniques like FT-ICR MS, oil shale microscopic pore and exploration of unconventional oil and gas within the pores have stepped into the new research focuses of related studies.
