Compared with beam pumping unit:
| Contrast project | Model | Floor space | Consume steel | Rod and tube partial-wear |
| Beam pumping unit | 12 types | 20-100 m2 | 29t | Have |
| Electric submersible oil reciprocation pump | 1140 | 5m2 | 1t | Nothing |
As follows with eight type beam pumping unit experiment of energy consumption results:
| Daily fluid production rate | Within 2t | 2t~5t | 6t~8t |
| Power saving rate | ≥80% | ≥60% | ≥40% |
Well liquid is to lower and go up (peupendicular hole) through linear electric motor outer wall and flow to oil well pump, and motor is dispelled the heat by well liquid, plays the effect of heating to well liquid simultaneously, enhances the mobility of well liquid.
The travelling-magnetic-field of motor stator alternation, has diluting effect to well liquid.
When motor stator is up, well liquid was inhaled into motor counter balance pocket by counter balance pocket inlet opening within 1 second time; When motor stator is descending, the well liquid in counter balance pocket was got rid of by mover extruding within 1 second time.
Go round and begin again, constantly local assault is produced to oil reservoir, also can increase the mobility of fluid.
The de-plugging problem of effective solution.
Linear electric motor are not activated electric current, and working power is direct current square wave.
Control cabinet takes filtering measures, can not produce the harmonious wave interference of inrush current to electrical network.
By oil field Local Area Network or mobile phone, monitoring and controlling is carried out to oil well Operational Limits and running state, realize wireless remote and patrol control.
