摘　　要：针对延长气田目的层深、地层老、可钻性差,常规钻井钻速慢、牙轮钻头很难提高钻速等实际问题,对延长气田的岩石可钻性和钻头选型进行了研究,建立了岩石可钻性剖面图;并优选了适合延长气田钻井的PDC钻头。通过现场试验,大幅度提高了延长气田的钻井速度,取得了显著的效果。The resources of Yanchang Gasfield is deep,formation is old,drillability is bad,conventional drilling rate is slow,the drilling rate is hard to be improved by cone bit.To these practical problems,rock drillability and bit selection have been studied,the stratigraphic section of rock drillability have been established,and PDC bit suitable for drilling in Yanchang Gasfield has been optimized.Through field test,drilling rate has been greatly improved,and significant results have been achieved.
