摘要
利用灰色局势决策理论综合评价了金刚石钻头的技术经济效益。结合近几ａ的钻探生产实践和科研成果，经验证和对比，为豫西地区优选高效、长寿、综合效益好的钻头提供了参考。
he basic principle of the Grey Decision Theory was discussed and the technical and economicbenefits of diamond bits were comprehensively evaluated using the grey theory. After the testing and verifyingin scientific researches and drilling practice in recent ysars in the western Henan,the diamond bits are selectedoptimally, which are of high efficiency,long life and good benefits.
