页岩气开采技术国际专利态势分析

页岩气是一种重要的非常规天然气资源，最早由美国勘探开发，目前在北美地区形成了成熟的评价方法和勘探开发技术，并推动了页岩气产业的发展。该文研究了国际页岩气的开发现状，并以汤森路透（ThomsonReuters）的Derwent专利数据库为数据源，基于关键词从国家、机构和研究主题等方面，对截至2013年的页岩气开采技术相关专利进行了分析，揭示了页岩气的关键开采技术特点和发展趋势，为我国页岩气的开发提出了对策和建议。

Research and Development of Shale Gas Exploration

As an unconventional natural gas resource, shale gas was first extracted in America. The evaluation method and exploitation technology for shale gas have been developed maturely and push the shale gas industry grows rapidly in North America. In this paper, the exploitation technology patents on shale gas from Derwent database of Thomson Reuters by 2013 were analyzed based on the quantity and key words from countries and institutions, as well as the focus themes. It reveals the key mining technology and development trends of shale gas, and then proposes countermeasures and suggestions for the shale gas development in China.
