Problems solved by technology

But this method is time-consuming and labor-intensive, and it is difficult to ensure effective control of the pumping well. Even if the manual adjustment parameters reach a balance for a while, it is difficult to maintain the balance, so that the pumping well is in an unbalanced working state

Embodiment Construction

[0024] Referring to Fig. 1, Fig. 2, Fig. 3, the pendulum balance intelligent control pumping unit of the present invention has a base 14, a frame 7, a motor 2, a reversing mechanism and a balancing mechanism. Wherein: the frame 7 is a cantilever structure protruding from the top, and the extension end is equipped with a rope pulley 8 to maintain the distance between the main body of the frame 7 and the wellhead 10, which is convenient for workover operations and downhole fault handling. The reversing mechanism is arranged on one side of the frame 7 and is composed of active and passive reversing wheels 4 and 5. Both the active and passive reversing wheels 4 and 5 are provided with forward and reverse spiral rope grooves to prevent the pulling of the rope. Damaged by extrusion friction during winding. Active reversing wheel 4 is contained in the bottom of frame 7, and is connected with motor 2 by belt transmission part 3, and passive reversing wheel 5 is contained in the middle...

Abstract

The invention relates to a swing-type balance intelligent control oil extractor which is mainly characterized in that the machine frame is in cantilever structure with extending top. The extending end of the machine frame is provided with a suspension rope wheel. A reversing mechanism is formed by a driving reversing wheel and a driven reversing wheel with a positive rope groove and a negative rope groove; the driving and the driven reversing wheels are connected through a reversing pull rope, the driven reversing wheel is fixedly connected with a suspension rope. A balancing mechanism adopting the swing-type balance is connected with the reversing mechanism through a bridge shaft in linkage; a motor is connected with a motor vector control cabinet which is connected with an intelligent control device through a data bus; wherein, the intelligent control device is connected with a flow sensor for monitoring the swabbing flow through a signal transmitting line. The oil extractor which can automatically control the stroke frequency and the stroke of the oil extractor according to the underground conditions, improve the motor efficiency and reduce the labor intensity, the invention has the advantages of simple structure, high balance degree and reliable performance as well as saving the electric energy and decreasing the producing and using cost, etc.

Description

technical field [0001] The invention belongs to the technical field of oil production equipment, and relates to a pendulum balance intelligent control pumping unit used for pumping crude oil in an oil field. Background technique [0002] In the known technology, although the beam pumping unit generally used in the oil field is easy to use and reliable, because the load of its motor is a periodic pulsating load, and superimposed there is an instant impact. In order to reduce the load fluctuation of the up and down strokes of the pumping unit, it is generally equipped with a balance block, which uses its rotational inertia to stabilize the load fluctuation. This method has a low balance coefficient and poor effect, and can only be used for high rotation speed and small load. At present, most oil fields are in the late stage of production, and a large number of poor oil wells need low stroke, long stroke, and large displacement extraction, and the low rotation speed leads to th...
