Mass data of well logging technology patents are formed along with the well logging technology and equipment rapidly developing in recent years. The purpose of this paper is to make full use of well logging technology patent information to promote self-innovation of well logging technologies. Based on the patent retrieval strategies of the key words combined with international patent classification, non-structural patent text data are mined deep and analyzed quantitatively. They reveal the relationships between well logging technology (WLT) patents data and technical research directions with concise charts. Some conclusions about the main technical characteristics, the focus and trend of research & development in the well logging patents are given, providing information support for making well logging technology patent market strategies and research schemes.%科技进步和油气勘探开发需求推动了测井技术及装备的快速发展,并形成了海量的测井专利文献.为使具有丰富信息的专利资源更好地服务于测井技术创新过程,在关键词与专利分类号(IPC)相结合的专利检索策略基础上,对非结构性的测井专利文本数据进行深层挖掘和量化分析,以简明的图表形式展示测井专利数据之间的关联及技术研发脉络,揭示测井专利的主要技术特征、研究热点及技术发展趋势,为制定测井专利策略和研发方案提供了信息支持.
