中国对页岩气的研究起步比美国晚,对页岩气勘探、开发、评价等技术仍处于探索和发展阶段,对页岩气主题相关的研究重点及方向也在变化。文章使用复杂网络方法,建立了页岩气主题关键词共文献网络,分析了2006—2015年中国知网上所有页岩气的主题文献。得出:从2011年开始,中国页岩气基础理论研究取得实践性突破;从2013年开始,页岩气的研究重点方向趋于集中;2015年中国页岩气完成第一阶段的研究;中国页岩气发展经历了从认识页岩气到页岩气开发技术研究再到储层特征理论的过程;中国页岩气开发实践进度高于页岩气基础地质理论研究进度。
The research on shale gas in China started later than that in the United States. Techniques for exploration, development and evaluation of shale gas are still under exploration and development. The research focus and direction on shale gas topics are also changing. In this paper, we use the complex network method to set up a co-literature network of shale gas keywords and analyze the theses of all shale gas in CNKI from 2006 to 2015. It is concluded that the shale gas basic theory research in China has made practical breakthrough since 2011, the focus of shale gas research tends to be concentrated from 2013, the first phase of shale gas research in China completed in 2015, The development of shale gas has gone through from the understanding of shale gas to shale gas development technology research to the reservoir characterization process. The progress of shale gas development in China is higher than that of shale gas basic geological theory.
