Intelligent winch type pulling oil production system

Abstract

The invention discloses an intelligent winch type pulling oil production system. The system comprises a drive assembly (1), a rack (2), an oil pumping rope (3) and a control device (9), wherein the drive assembly is provided with a winding drum (11) and a drive device (12) driving the winding drum (11) to rotate; a pulley (21) is installed on the rack; one end of the oil pumping rope is wound on the winding drum (11) and the other end thereof is connected with an oil production device (4) in an underground oil well pipe (5) by bypassing the pulley (21); the control device is used for controlling the drive device (12) to rotate; the oil production device (4) is provided with an underground liquid column height detector (6); and the underground liquid column height detector (6) transfers the detected liquid column height signal to the control device so that the control device controls the drive device (12) to act when receiving the preset liquid column height signal, thus driving the oil production device (4) to pull the liquid in the oil well pipe (5) out of the well mouth. The system has high oil production efficiency, reduces the energy consumption and reduces equipment wear.

Description

technical field [0001] The invention relates to an oil production equipment, in particular to an intelligent winch-type lifting oil production equipment. Background technique [0002] At present, the beam pumping unit is widely used in mechanical oil recovery. The beam pumping unit is the bottom power equipment of the downhole oil pump, commonly known as the kowtow machine, which transmits the reciprocating motion of the suspension point of the pumping unit to the pumping unit through the sucker rod. For the downhole plunger pump, when pumping oil, the transmission of the motor becomes the up and down movement of the donkey head through the gearbox and the crank connecting rod structure, and the donkey head passes through the polished rod and the sucker rod to drive the plunger of the deep well pump to move up and down, thereby continuously The oil or oily liquid in the well is pumped out of the wellbore. [0003] The oil recovery method of the beam pumping unit is suitable...

AI Technical Summary

Problems solved by technology

[0003] The oil recovery method of the beam pumping unit is suitable for oil wells with large oil production. The beam pumping unit can quickly and uninterruptedly pump out the oil or oily liquid in the oil well. For oil wells, due to insufficient oil supply in the formation, the recovery of the oil well liquid level is slow, and dry pumping often occurs when beam pumping units are used for oil production, resulting in loss of electrical energy and wear on equipment

If you want to wait for the liquid level to recover before pumping oil, you must rely on manual control of the start and stop of the pumping unit, and the time for manually controlling the start and stop of the pumping unit is not easy to grasp, and improper time for manually controlling the start and close of the pumping unit may easily cause jams Well and operation rework; at the same time, since the pumping unit is generally installed in the field, it is required to work around the clock, and manual control increases the operating cost and brings inconvenience to production

Moreover, the structure of the beam pumping unit is complicated, the cost is high, and the floor area is large, so it cannot be used in some places where the available space is small
