Description

The invention relates to oil production engineering, in particular, to well pumping installations, and can be used in the oil industry in the operation of wells producing high viscosity and high paraffin oils.

The purpose of the invention is to expand the range of use.

The drawing shows a schematic of a well pumping unit for dobji oil, a general view.

The well pumping unit for oil production contains a rod end 1 placed in the cylinder 2 of the rod pump connected to the column of the rod rods 3 plunger 4 with the discharge valve 5 installed in it and the suction valve 6. Go to the rod rod 1 the reagent meter 7 is connected In the cylinder 8, with the formation of the sub plunger chamber 9 of the dispenser, a spring loaded pressure valve 10 is installed and. a plunger 11 rigidly connected by means of a hollow rod 12 to a hollow plunger 4 of a sucker-rod pump 1. The sub-plunger chamber 9 of the reagent dispenser 7 communicates with the bypass channel -13 through the suction valve 14 of the dispenser when the plungers 4 and 11 move upwards.

The plunger 11 of the dispenser 7 of the reagent is made hollow, and the water channel 13 is made through the hollow plunger 4;

The main pump 1, above which the suction valve 14 of the dispenser 7 is located, and the watering 13 is hydraulically connected with the roll column 3 of the rods 3.

. Cylinder 2 of the sucker-rod pump 1 is connected to the column of pump tubes 15.

The plunger 4 of the sucker-rod pump 1 is installed in the cylinder 2 with an image of

flows through the pump suction valve 6 into its sub plunger chamber 16, while the fluid in the pump supra plunger chamber 17 is displaced into the column of pump tubes 15 and further to the surface. In this case, the reagent from the hollow column of the pump rods 3 made through the suction valve 14 of the dispenser 7 and the bypass channel 13 enters the sub plunger chamber 9. the reagent dispenser, fills its space.

When downward, the columns of the pump rods 3 and, with it, the hollow plungers 4 and 11, respectively, of the sucker-rod pump 1 and the reagent dispenser 7, are suction valves 6 and 14 closed. The reservoir fluid, which is located in the sub-plunger chamber 16 of the sucker-rod pump 1, flows into its supra-plunger chamber 17 through the pump valve 5, which has opened the injection valve, while the reagent from the sub-plunger chamber 9 of the dispenser 7 through the open sub-plunger pressure valve 10 displaced into the well to receive a sucker-rod pump. As the reagent is consumed by a single injection into the cavity of the column, the sucker rods 3 fill it.

If necessary, the proposed installation also allows pumping the coolant into the well through the hollow column of pump rods 3, through the suction valve 14 of the metering device, through the bypass channel 13, the hollow rod 12, the hollow plunger 11 of the metering unit and its sub plunger chamber 9, through the spring-loaded discharge valve 10 .
