A、定子A, stator定子是螺杆泵的一个关键部件,并直接影响到井下机组的寿命。定子制造质量越高,井下机组的寿命就越长。定子的作用就是提供转子工作和液体抽汲的螺旋腔,莫诺,其结构非常简单,由钢制外壳和塑料/橡胶衬套内腔有双螺旋、三螺旋、四螺旋甚至五螺旋、六螺旋,在相同尺寸下,螺旋数越多,泵的排量越高。The stator is a key component of the screw pump, which directly affects the life of the downhole unit. The higher the quality of the stator, the longer the life of the downhole unit. The role is to provide a rotor stator and liquid pumping spiral c***ity drain, the structure is very simple, a steel shell and a plastic / rubber bushing c***ity with double helix, three helix, four or even five, six spiral helical spiral, in the same size, the number of spiral, the displacement of the pump is high.



杆柱脱落Rod shedding杆柱脱落也是螺杆泵常发生的一种故障现象,表现为运行电流很低,井口也无产液,正反循环油套不连通,通过对扣或下入抽油杆打捞工具就可以进行处理来***生产。抽油杆脱落也有两种情况,一是脱扣,一是掳扣。造成脱扣的原因是停机后抽油杆柱扭转变形余能释放引起杆柱反转,可以采取在地面和抽油杆柱上安装防倒装置进行防止。造成杆柱掳扣的原因有三个:一个是稠油井在长时间关井后再启泵时,启动扭矩特别大,把螺纹损坏了;一个是油特别稠,螺杆泵长期在高扭矩下工作而把螺纹损坏;再有一个原因是定子部分脱胶,转子转不动造成的。



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 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.
