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，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 motors no load current. besides the gas with a single strand of gas, the wellhead basically has no liquid production,&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&unloading joint on the stator is connected by loosening screw thread;&use the oil pipe anchor/tension packer to fix the screw pump.
ｄ、限位器d, limiting device限位器为一个底部带限位板和流-道的短节，接在定子的尾部，其作用是施工作业时给转子限位以防止下入过头而失去作用和杆柱脱落时防止杆柱掉入井底。the limiting device is a short section with bottom limit plate&distribution channel, which is connected to the tail of the stator. its function is to limit the rotor to the rotor during ctruction1, so as to prevent it from falling into the overhead&lose its function&prevent the rod from falling into the bottom when the rod string falls off.
现将在现场采用同规格的g型单螺杆泵及齿轮泵在完全相同工况条件下并在输送出口压力为1 mpa时进行了简单的对比,测量了这样两组数据:当输送重油粘度约为75×102-6m2/ s时,齿轮泵出口压力表的指针跳动幅度为±0.16,三螺杆泵出口压力表的指针跳动幅度为±0.05,双螺杆泵出口压力表的指针跳动的幅度为±0.04 ;而当输送重油粘度约为150×102-6m2/ s时,齿轮泵出口压力表的指针跳动幅度为±0.22,三螺杆泵出口压力表的指针跳动的幅度为±0.06,双g型单螺杆泵出口压力表的指针跳动的幅度为±0.04。这说明,g型单螺杆泵在重油的输送和喷燃过程中,介质的输送压力很稳定。并且随着介质粘度的加大,g型单螺杆泵(尤其是双螺杆泵)的无脉动特点相比之下更为明显。
