By the active flexible operation control technology, the power servo drive technology, the downhole conditions and sys?tem operation state identification and diagnosis technology, and the orbit transfer optimization control technology, flexible operation technology realized the pumping of non uniform lifting, changed the inherent oil pumping polished rod speed mode, optimized the process of downhole pumping and made up the inherent defects of the performance of four connecting rod. What’s more, without any changes of the pumping unit structure, it achieved the goals of improving the efficiency of downhole, ensuring the system to run on demand and reducing equipment attrition rate and production consumption. This technology does not need special requirements on submergence depth, but needs strictly requirements on the balance of pumping unit. The better the balance condition is, the bet?ter the application effects are. The application has realized the effect of reducing the power consumption by 30.7 kWh per day and improving the power factor of 0.64. And the energy saving rate is 13.75 %.
