A linear motor is a power unit that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism. It is understood that because the linear motor pumping unit moves 90% of the entire stroke during the running process, it overcomes the maximum load of the sucker rod caused by the simple harmonic movement of the beam-type four-link pumping unit. The problem of excessive alternating load is reduced, the stroke loss is reduced, the effective stroke of the plunger of the pumping pump is increased, and the service life of the sucker rod is prolonged.
The linear motor pumping unit is suitable for the process requirements of oil wells with high viscosity, high wax content and high gas to oil ratio. It can effectively change the peak value of maximum and minimum loads and adapt to the requirements of special well conditions. It also makes it possible to lose minor wells and reduce leakage. Quantity, extend the inspection cycle of the well.
It is understood that this technology is applied at home 23-19 well this year, which has changed the traditional process and often caused difficulty in opening the well and rod fight. The daily liquid production increased from 25 to 30.5 square meters, and the daily electricity consumption was 85 kilowatt hours.
Dagang Oilfield Linear Motor Pumping Unit Developed Successfully
The first linear motor pumping unit of Dagang Oilfield has been successfully tested in the third oil production plant of Dagang Oilfield Company. According to industry insiders, this marks a new step in the expansion of the heavy oil wells in Dagang Oilfield and the improvement of machine utilization efficiency.
