Abstract

The invention can be used for the extraction of oil and gas. The purpose of the invention is to increase the durability of the borehole pump and the string of pump rods by increasing the stroke length of the polished rod by additionally moving the suspension point of the column of pump rods relative to the balancer head and reducing the rolling number of the latter. The electric motor 2 and the reducer 3 are mounted on the frame 1. The crankshafts 5 are placed on the output shaft 4 and connected to the connecting rods 6, which are connected to the balance bar 8 by the cross beam 7. The balance bar 8 is mounted on the rack 9 located on the frame 1 and provided with a head 10 having rollers 11. Through the rollers 11 passes a flexible bond 12 in the form of ropes 13, one ends 14 of which are connected to the suspension 15 of the rod.

Description

The invention relates to an oil production technique, in particular, to a drive of well pump sucker pumps, for example, pumping units, and can be used in the oil and gas industry for oil and gas production.

The purpose of the invention is to increase the durability of the borehole pump and the string of pump rods by increasing the stroke length of the polished rod by additionally selected in accordance with the required increase in the stroke length of the polished rod.

In the horizontal position of the balance bar 8, the suspension point of the column of the pump rods is below the neutral position of the additional cables 17 by the amount of their attachment radius to the cranks 5. Further, with the upper arrangement

tubes of sucker rods with respect to the balancer head and a decrease in the number of swings of the latter.

FIG. 1 is schematically represented

Movement of the suspension point of the head 10 of the balance bar 8, the position of additional ropes 17 is considered neutral, and the relative upward movement of the suspension point of the column of rods occurs by the amount of radius of the pumping unit when the connecting rods 6 are horizontal-mounted to the cranks 5.
