Abstract
Because of its matured lifting technology and perfect supporting process, beam unit-rod pumping is applied widely in oilfield development. But as applied in low liquid production wells, the proportion of idle power consumption is large. Therefore, the lifting technology of electric submersible piston pump was studied to decrease the energy consumption. Based on the supporting technologies of electrical heating, liquid level automatic monitoring and remote control, the technology of down-hole intelligent intermittent pumping was developed, which can decrease the energy consumption, and provide technical support for the construction of digital oilfield.
