我国十年来煤层气研究热点分布转换与产业发展

Transformation and industrial development of coalbed methane study hot point distribution in passed ten years of China

采用关键词检索、Cite Space数值分析与统计分析相结合的研究方法,统计了CNKI中国期刊全文数据库2003—2013年所收录的煤层气领域论文,分析了我国煤层气规模化开发十年来的研究进展。结果表明,在我国煤层气领域,地质与勘探、开发技术、综合利用与环保三大方向研究受到的关注程度差异明显。关注的重点集中在沁水和鄂尔多斯两大盆地以及吐哈、两淮等地区,并扩展到黔西、豫西、滇东、准噶尔等地;煤层气开发技术研究受到高度重视,关注热点逐年增强与变化的趋势十分明显;煤系三气(煤层气、页岩气、致密砂岩气)共探共采被纳入研究视野。文献非线性增长趋势显示,十年来我国煤层气产业经历了不均衡发展和均衡快速发展2个阶段,不同阶段产业发展的需求引导了研究热点的阶段性转换。同时指出,两阶段研究明显存在一些共性不足,如对煤层气综合利用与环保、产业政策与矿权管理、深部煤层气的研究与实例分析较少。研究结果对了解我国煤层气产业发展脉络、制订后续研究计划均有所裨益。

The keyword search,Cite Space numerical analysis and statistic analysis combined study method was applied to count the coalbed methane literatures collected in the CNKI（ China Knowledge Resource Integrated） Database from 2003 to 2013 and analyzed the study progress of China coalbed methane scale development in passed ten years.The results showed that in China coalbed methane area,a three directional study on the geology and exploration,development technology,comprehensive utilization and environment protection was concerned obviously with different degree.The concerned focal points were concentrated on Qinshui Basin and Ordos Basin as well as Tuha Area,Huainan and Huaibei Basins and other area and were expanded to Qianxi,Yuxi,Diandong,Dzungaria and other places. High attention was made on the study of the coalbed methane development technology and the hot concerned point steadily increased annually and the variation tendency were very obvious. Coal measure ＂coalbed methane,shale gas and compact sandstone gas＂simultaneous exploration and simultaneous mining were included in the study.The nonlinear increasing tendency of the documents showed that in passed ten years,China＇s coalbed methane industry had experienced a disproportion development stage and a proportion rapid development stage and the requirement of the different stage industrial development would guide the stage conversion of the study hot point.Meanwhile,the paper pointed out that there was some common deficiencies existed in the two stage study,for example,less study and case analysis on coalbed methane comprehensive utilization and environment protection,industrial policy and mining right management,the deep coalbed methane. The study results would have benefits to China coalbed methane scientific academia to understand the industrial development skeleton,to set up the late study plan.
