基于文献大数据的我国煤层气研究现状与热点分析

CBM Research Status and Hot Spots Analysis in China Based on Literature Big Data

我国煤层气资源丰富,勘探开发起步较早,但近年来研究趋缓,增产遇到瓶颈。基于中国科学引文数据库中2008～2017年以"煤层气"为篇名的1 092篇文献数据,分析我国煤层气学术研究的趋势、研究力量、研究方向、研究热点及高被引论文等。结果表明,当前我国煤层气学术论文增长趋缓;煤层气学术研究形成了不同研究群体间的合作关系,中国矿业大学秦勇等学者发文量较高,是我国煤层气学术研究的中坚力量;《天然气工业》《煤田地质与勘探》《煤炭学报》刊载我国煤层气学术论文最多;学者们围绕煤层气储层、开发技术、成藏、数值模拟等主题开展研究,形成当前我国煤层气学术研究的热点。

China has abundant CBM resources with start early exploration and exploitation.But in recent years,the CBM research is slowing down,production increasing met bottleneck.Based on 2008~2017 data from 1092 literatures under the title“CBM”in the Chinese Science Citation Database(CSCD),have analyzed the CBM academic research trends,capacity,orientation,hot spots and mostly cited papers etc.in China.The result has shown that the increasing of CBM academic papers is slowing down at present;CBM academic research has formed partnership among different research groups;scholars including Professor Qin Yong of China University of Mining and Technology have higher total articles in publication list,thus the backbone of CBM academic research in China.The magazines of“Natural Gas Industry”,“Coal Geology and Exploration”and“Journal of China Coal Society”have most academic papers on CBM published in China.Around the themes of CBM reservoir,exploitation technology,reservoiring,numerical simulation etc.,scholars have carried out CBM researches and formed CBM academic research hot spots in China at present.
