Spiral type synergistic oil pumping device

Abstract

The invention discloses a spiral type synergistic oil pumping device, which comprises a casing, an oil collecting cover, a detection sensor, a main shaft, a spiral blade, a wind plate, a suction device and a rotating motor; the bottom of the casing is equipped with an oil collecting cover, A detection sensor is installed inside the oil collecting cover, a rotating motor is installed on the top of the housing, and a main shaft is installed in the housing. The output shaft of the rotating motor extends into the housing and connects with the top of the main shaft. blades, wind plates are installed on the spiral blades, and a suction device is installed on the main shaft, and the suction device is fixed between the spiral blades and the rotating motor; the present invention facilitates the realization of spiral oil pumping, and the working efficiency High, save time, large oil pumping capacity.

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
