摘　　要：对为解决连续管钻井作业中存在的连续管弯曲受阻和摩擦自锁所采用的连续管振动器 (CTV)的摩擦压力损失进行了初步计算与分析 ,结果表明 ,通过 CTV的压力损失仅为 0 1 3 8MPa,远小于连续管作业的工作压力 ,说明 CTV不会对连续管作业的钻井液压力系统产生不利影响。A CT(coiled tubing) vibrator (CTV) is used in eliminating obstructions due to buckling and self locking due to friction in CT A preliminary calculation and analysis of the friction pressure loss from CTV is carried out The results show that pressure loss across CTV is only 0 138MPa,much lower than working pressure of CT in work and CTV would not produce a disadvantageous impact on the pressure system of drilling fluids when CTV is working
