摘　　要：涡轮钻具在国外已经是一套成熟工具和提速方法,在国内没有成熟的产品,还没有形成工业化应用和处于探索阶段,并受设备条件的限制特别是泵压的限制,文章对不同钻井液密度下涡轮钻具的压降变化进行了分析研究,通过实例对比给出了总泵压的变化幅值,推荐使用的钻杆尺寸对今后涡轮钻具的试验应用有较强的指导意义。Turbodrill has been a mature tool and technique to improve the ROP abroad.However,there have been not mature productions and not industrially applied in China.Trial ones are restricted by drilling equipments especially by the pumping pressure in drilling pad.The change of pressure drop of burbodrill was analyzed under different drilling fluid density,the change range of the pumping pressure was given and the DP size was also recommend in this paper.It can direct the burbodrill experiment in the future.
