Abstract: A heavy oil lifting device and a heavy oil lifting method are disclosed. The device includes: a plurality of liquid injection pumps each including a liquid inlet and a liquid outlet and configured to intake in liquid and discharge the liquid after pressurization; a control valve including a first end and a second end, the liquid outlets of the plurality of liquid injection pumps are connected with the first end; a power liquid transmission pipe connected with the second end and configured to transmit the liquid after pressurization; an operation pump connected with the power liquid transmission pipe, and the liquid after pressurization is used as power liquid to drive the operation pump to reciprocate; the control valve is in switchable communication with the liquid injection pump so that the power liquid transmission pipe is in switchable communication with the liquid injection pump.

Abstract: The present disclosure relates to the technical field of well site energy management, and in particular to a comprehensive energy management system and method for the fields of oil and gas field drilling and oil and gas field yield increase business. The energy device adopted by the application combines all power energies on site, thus realizing an integrated centralized control strategy of energy. The purpose of strong resistance to load fluctuation, and peak storage and valley release of electric energy is achieved. A cloud server is adopted to seamlessly combine site with local control, so that manual remote operation is realized. The problem that personnel cannot reach the site to handle faults, and consequently, loss is caused due to shutdown is solved. Limited resources are reasonably utilized to the greatest extent.
