本文对1987~2011年国家自然科学基金中石油相关项目申请时间、项目金额与年代的关系以及项目依托单位进行文献计量分析,对项目关键词进行共现关键词对处理,利用UCINET将共现频次较高的关键词进行可视化,并采用知识图谱方法进行相关的分析。对高频关键词共现的相关分析,可以直观化地了解到石油科技研究与哪些方面的相关程度较高,或者说石油科技的研究着眼于那些大的方面,进而总结出石油项目目前研究主要集中在石油产业链的中游。本文给石油科技的研究引入了一种新的研究方法,从相关的结果中分析石油科技目前的研究状态,以及存在的一些不足。
In this paper, from 1987 to 2011, the application time of NSFC-PetroChina-related projects, the relationship between the project amount and the age and the bibliographic analysis of the project relying units, the co-occurrence keywords of the project keywords were dealt with. The frequency of co-occurrence with UCINET High keywords for visualization, and the use of knowledge mapping methods for related analysis. Co-occurrence of high-frequency correlation analysis of key words, you can intuitively understand the oil science and technology and what aspects of a higher degree of correlation, or oil science and technology research focused on those aspects, and then concluded that the current oil research project mainly Concentrated in the middle reaches of the oil industry chain. This paper introduces a new research method to petroleum science and technology, analyzes the current state of petroleum science and technology from the related results, and some existing problems.
