摘　　要：大庆油田普遍采用刮刀钻头钻调整井。现场试验表明，对刮刀钻头钻井参数进行优选优配，在同等条件下比牙轮钻头可获得更高的经济效益。本文主要介绍大庆油田１９９２年２０多口井现场试验情况，同时探讨了钻头选型、喷嘴组合、泵压、排量、钻压、转速及钻井液参数对刮刀钻头钻速的影响规律。Drag bits are commonly used to drill adjustment wells in Daqing Oilfield. Field tests display, through optimization of bit parametrs and under the equal conditions,the use of drag bits can obtain more economic benefits than those ofrock bits.The paper gives a general introduction to the field tests in 1992,and the effects of bits'selection,jet nozzles'combinations,mud pump pressure,flow rate,bit weight and rotatary speed and drilling fluid parameters on the ROP of drag bitsare studied.
