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(Thomson Reuters)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。
Shale gas is an important unconventional natural gas resource. It was initially explored and developed in the United States. At present, shale gas has developed mature evaluation methods and exploration and development technologies in North America and promoted the development of the shale gas industry. This paper studies the current status of the development of international shale gas and uses the Derwent patent database of Thomson Reuters as a data source. Based on the key words from the national, institutional and research topics, the shale gas Mining technology-related patents were analyzed to reveal the shale gas key mining technology features and trends, for the development of shale gas in our country put forward countermeasures and suggestions.
