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] see figure 1 , Fig. 2, Fig. 3, pendulum balance intelligent control pumping unit of the present invention has base 14, frame 7, motor 2, reversing mechanism and balance 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 part of frame 7, and...

Abstract

The invention relates to a pendulum-type balance intelligent control pumping unit, which is mainly characterized in that the frame is a cantilever structure extending from the top; The main and passive reversing wheels are composed of main and passive reversing wheels. The main and passive reversing wheels are connected by reversing ropes. The passive reversing wheels are fixed with suspension ropes. Connected and linked, the motor is connected with a motor vector control cabinet, the control cabinet is connected with an intelligent control device through a data bus, and the intelligent control device is connected with a flow sensor for monitoring the swabbing flow through a signal transmission line. The pumping unit can automatically control the strokes and strokes of the pumping unit according to the downhole conditions, improve the motor efficiency, reduce labor intensity, and has the advantages of simple structure, high balance, reliable performance, energy saving, lower production and use costs, etc. advantage.

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...
