摘要
利用关键词检索对石油装备行业中的钻井装备、采油(气)装备、完井装备等几大领域分别进行全时段专利数据的检索,系统分析国内石油装备行业的现状、发展趋势以及发展机遇,给出促进我国石油装备行业发展的对策和建议。结果表明,中国石油装备行业专利申请量在2005-2012年之间呈加速上升的态势,而其中钻井装备的专利数量最多,并且申请人主要集中在国企及院校,地域上主要集中在北京、四川等地,高端装备申请专利较少。
Based on the characteristic of oilfield equipment industry, patent data of drilling equipment, nil （gas） exploring equipment, and completion equipment area in oilfield equipment are searched in all time. The trend, current situation and chance of oilfield equipment industry are analyzed systematically. The results show that number of patent development for oilfield equipment industry of China grew slowly before 2005 ; but the development was in an accelerated speed between in the years from 2005 and 2012 ; between 2012 and 2014 the growth rate declined. The number of drilling equipment patent was the biggest in all areas of oilfield equipment industry. The patent applicants were concentrated in state - owned enter- prises and colleges or in Beijing, Sichuan in spatial distribution. The number of invention patent was increasing year by year despite of the limited applications for high - end patents.
