摘　　要：以现场试验资料为依据，分析了短翼下喷嘴刮刀钻头、ＰＤＣ钻头以及中长和加长喷嘴牙轮钻头的使用效果，并引用优先数法评选出大庆长垣东部地区中深井的最优钻头系列，为提高中深井钻井速度提供了可靠依据。Based on field experiment data, theapplication result of short-wing-down-nozzle dragbit, PDC bit, mid-extended and extended-nozzlerolling cone bit was analysed. By the method of priorindex,the bit type series was selected for mid-deepwells in Eastern Changyuan area, Daqing Oilfield,which provided a reliable verification for increasingthe mid-deep well drilling speed.
