管柱脱落的故障现象是：运行电流很低，基本上是电机的空载电流，除了有一股一股的气外，莫诺，井口基本上无产液，正发循环时油套连通。The failure phenomenon of the string is: the running current is very low， basically the motor"s no load current. Besides the gas with a single strand of gas， the wellhead basically has no liquid production， and the oil sleeve is connected when circulating.减少管柱脱落的措施有：将油管上扣扭矩由原来的值提高到值；采用油管螺纹垫片；定子上的装卸短节采用防松螺纹连接；采用油管锚或张力封隔器固定螺杆泵。The measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading and unloading joint on the stator is connected by loosening screw thread; and use the oil pipe anchor or tension packer to fix the screw pump.
管柱脱落是自由式管柱结构经常发生的一种现象，这是由于正常运转时转子旋转对定子产生的摩擦扭矩方向实际上是定子及油管的连接螺纹的卸扣方向，如果摩擦力矩大于油管扣的上扣扭矩，油管就脱扣。当尾管很重时，还会出现螺纹掳扣。当管柱脱落时，通过作业重新连接好就能恢复生产。如果未发生螺纹掳扣，可以采取对扣方式打捞，如果发生掳扣，必须下打捞工具进行打捞。Column shedding is a common phenomenon of free tube structure， which is due to the direction of rotation of the friction torque generated by the stator rotor during normal operation is actually a stator and tubing connection1 screw shackle direction， if the friction torque is greater than the pipe le on torque， oil pipe tripping. When the tail pipe is very heavy， there will also be a thread caption. When the pipe column falls off， the production can be restored by reconnecting the work. If the le is not threaded， it can be salvaged by the way of the le. If the le occurs， the fishing tool must be salvaged.
