摘　　要：油气钻井技术的评价对于科学合理地制定我国石油工业科技发展战略具有重要意义。针对油气钻井技术的特点,建立了油气钻井技术评价指标体系。指标权重的确定采用权值因子判断法,该方法计算简单、实用。应用多指标评价的新方法-主成份投影法对14项油气钻井技术进行了评价。应用结果表明,该方法是合理的。Our oil and gas industry is faced with many new challenges in 21st century. Comprehensive evaluation of oil and gas drilling technology is very important to scientific and reasonably lay out our science and technology development strategy in oil and gas industry. Considering the characteristics of oil and gas technology, a technical evaluation index system was established. The weight of each index was obtained by the weight factor decision method. Its calculation is simple and practicable. A new method of multi - index comprehensive evaluation ( i. e. the principal component projection method) was applied to evaluate fourteen oil and gas drilling technologies. The application results indicated that it is feasible.
