摘　　要：易漏失地层钻进及漏失治理效率差,容易导致工期及效益损失。优选了提速堵漏钻具组合,使用PV配合直井测斜仪、堵漏短节组合,既满足防漏堵漏需求,又能监测、控制井斜,同时释放参数,达到钻井提速的效果。介绍了本组合的工作原理,并针对提速堵漏钻具组合在渤海某探井的应用情况进行了分析,结果表明本组合较常规简易钻具组合的机械钻速提高了200%,具有较大的推广前景。Poor drilling and leakage control efficiency in leakage-prone formations may easily lead to loss of construction period and benefits.The speed-increasing plugging drilling tool assembly is optimized,and the combination of PV,vertical well inclinometer and plugging sub is used,which not only meets the needs of leak prevention and plugging,but also monitors and controls well deviation,and releases parameters at the same time to achieve the effect of increasing drilling speed.The working principle of this combination is introduced,and the application of the speed-improving plugging drilling tool assembly in an exploration well in Bohai Sea is analyzed.The results show that the ROP of this combination is 200%higher than that of the conventional simple drilling tool Promote prospects..
