Submersible direct-drive screw pump oil production equipment

The invention discloses submersible direct-drive screw pump oil production equipment which comprises an oil production executing mechanism and a control mechanism. The oil production executing mechanism comprises a wellhead device, an oil pipe, a screw pump and a motor. The screw pump is located beneath the oil pipe, and an oil outlet of the screw pump is communicated with the oil pipe. The motor is located below the screw pump and used for driving the screw pump to work. The control mechanism comprises an oil inlet sensor, an oil outlet sensor and a control cabinet. The control cabinet is used for receiving signals collected by all the sensors and controlling the motor to work according to the received signals. According to the submersible direct-drive screw pump oil production equipment, the oil pipe, the screw pump, the motor and the like are arranged under a well, a series of traditional components like a kowtow machine and an oil pumping driving rod are omitted, no mechanical rotating members exist on the ground, the occupied area is small, noise is low, working efficiency is high, and the failure rate is low; the oil inlet sensor and the oil outlet sensor are arranged under the well so that the downhole operating condition can be monitored in real time; the control cabinet controls the rotating speed of the motor according to the received signals, and thus the oil production executing mechanism can operate intelligently and efficiently.
