摘　　要：在未来几十年,油气仍将是人类的主力能源。随着世界和我国油气工业的发展,那些规模大、储量大、资源丰度高、易勘探、好开采的中、高渗透油气资源在整个剩余油气资源总量中所占的比重越来越小,以前不被重视的低渗透油气资源逐渐成为油气勘探开发的重点,低渗透油气资源研究的重要性日益凸显。专利能够很好地反映某个领域科学和技术的发展情况,是开展相关领域技术发展态势分析的重要工具。选用德温特创新专利索引(DII)为主要数据源,以汤森数据分析师(TDA)为主要分析工具,对1968年以来的低渗透油气资源勘探开发国际专利进行了分析,探讨了该领域技术的未来发展趋势。从1971年开始出现低渗透油气资源研发专利,此后专利数量逐渐增加,特别是近20年以来快速增加,反映了国际低渗透油气资源研发呈现快速发展的趋势;专利技术领域主要集中在低渗透油气层的识别和改造技术、钻采工艺技术等方面,反映这些领域是技术研发的热点和重点;美国、加拿大、俄罗斯等国家是国际低渗透油气资源研发专利的主要拥有国,反映了低渗透油气资源大国同时也是技术大国;专利技术主要为大油气田公司所拥有,反映企业是低渗透油气资源研发的主体;近年来我国在低渗透油气资源研发方面有较快发展,但与技术领先国家仍有一定差距。In the coming decades, oil and gas will remain the main kinds of human energy. With the development of oil and gas industry, the middle-high permeability oil and gas resources are decreasing, which are large in scale, large reserves, high abundance of resources, easy to exploration and mining well. The research on lowpermeability oil and gas resources becomes more and more important. Using Thomson data analyzer （TDA） as the main analytical tool, patenting activities of exploration and development technologies for low-permeability oil and gas resources were analyzed based on the data from Derwent Innovations Index （DH）. Since the first patent of low-permeability oil and gas resources applied in 1971, the number of patents has been increasing, especially in the latest 20 years. The patents focus on low-permeability oil and gas layer of identification and transformation technology, drilling technology, etc. The United States, Canada, Russia are the major patents possessor states. Patents are mainly owned by super oil ＆ gas companies. In recent years China have rapid development in R ＆ D of low-permeability oil and gas resources, but the country remains a certain gap to the technology leaders.
