Screw type efficient oil pumping device

Abstract

The invention discloses a screw type efficient oil pumping device. The screw type efficient oil pumping device comprises a shell, an oil gathering cover, a detecting sensor, a spindle, screw blades, air foils, an air suction device and a rotating motor; the oil gathering cover is arranged on the bottom of the shell; the detecting sensor is arranged in the oil gathering cover; the rotating motor is arranged on the top of the shell; the spindle is arranged in the shell; an outputting shaft of the rotating motor extends into the shell and is connected to the top of the spindle; the screw blades are arranged on the spindle; each screw blade is provided with the corresponding air foil; the spindle is also provided with the air suction device; and the air suction device is fixed between the screw blades and the rotating motor. By the screw type efficient oil pumping device, screw type oil pumping is convenient to implement; work efficiency is high; time is saved; and oil pumping amount is large.

Description

【Technical field】 [0001] The invention relates to the field of oil pumping units used in oil field development, in particular to a spiral type synergistic oil pumping device. 【Background technique】 [0002] The pumping unit is a kind of mechanical equipment for oil extraction. The oil is pumped out of the well by means of pressurization. When the pumping unit is upstroke, the oil pipe elastically shrinks and moves upwards, driving the mechanical unblocking oil extractor to move upwards and hitting the sliding sleeve to generate vibration; at the same time , the positive check valve is closed, and the variable diameter piston assembly blocks the oil. When the pumping unit downstrokes, the oil pipe elastically elongates and moves downward, driving the mechanical unblocking oil extractor to move downward, and impacting the sliding sleeve to generate vibration; at the same time, The reverse check valve is partially closed, and the variable-diameter piston assembly still blocks t...

Problems solved by technology

[0002] The pumping unit is a kind of mechanical equipment for oil extraction. The oil is pumped out of the well by means of pressurization. When the pumping unit is upstroke, the oil pipe elastically shrinks and moves upwards, driving the mechanical unblocking oil extractor to move upwards and hitting the sliding sleeve to generate vibration; at the same time , the positive check valve is closed, and the variable diameter piston assembly blocks the oil. When the pumping unit downstrokes, the oil pipe elastically elongates and moves downward, which drives the mechanical unblocking oil extractor to move downward, and hits the sliding sleeve to generate vibration; at the same time, The reverse check valve is partially closed, and the variable-diameter piston assembly still blocks the annular oil channel of the oil jacket, so that a high-pressure area is formed in the area below the reverse check valve. There are some problems in the use of the existing spiral oil pumping device, especially the oil pumping efficiency cannot meet the demand, and the problem of wasting time needs to be improved urgently
