基于专利信息的页岩气勘探开发技术发展趋势研究

页岩气是近年来备受关注的非常规能源,因此页岩气勘探开发相关技术也成为技术研发焦点。目前国内外已经形成了大量的专利技术,采用国际专利分类法,通过德温特国际专利数据库和中国知识产权网专利数据库进行检索分析,发现整个页岩气技术群主要集中在干馏、热采等15个专业领域,而钻井、固井、完井和压裂等相关专利却占比很少,但这4个专业的相关专利在2000年后得到了快速增加。从生命周期来判断,页岩气整体技术群的发展处于快速发展时期,预计将于2018年进入成熟期,而钻井、完井、固井和压裂等4个上游相关专业却刚刚进入快速发展时期。

Study on Development Trend of Shale Gas Exploration and Development Technology Based on Patent Information

Shale gas is a kind of unconventional energy which draws more concern in recent years, so the related exploration and development technologies become the focus. A large quantity of patented technologies has been currently created both in China and abroad. The catalog analysis is made based on the adoption of international patent classification method and using Derent international patent database and Patent database of China intellectual property network, it is found that the patent applications of whole shale gas technologies group are concentrated in 15 technological areas, such as dry distillation and and thermal recovery; while patents of drilling, cementing, well completion and fracturing have accounted very small propotion. But the related patents of these 4 fields are booming quickly. Judging from the life cycle, the shale gas technology is in a period of rapie development and will go to the maturation in 2018. The related upstream fields of drilling, cementing, well completion and fracturing is just entering the rapie development period.
