Description

The invention relates to mining, in particular to the oil industry, and can be used in the design of oil transportation systems using pulsed solenoids in downhole devices.

Known vibration pumps containing a housing with a suction pipe and discharge valves, a working chamber and a vibrator. However, the known pumps are characterized by structural complexity and low reliability.

Known well sucker rod pumping units containing columns of pump pipes and rods, a pump with a receiving pipe and placed in it check valve.

A disadvantage of the known devices is a decrease in the permeability of the bottom-hole formation zone during well shutdowns due to the lack of free volume for fluid accumulation in the downhole equipment. The closest to the invention in technical essence is a vibrating pump containing a cylindrical body, pressure valves, working bodies

which are mounted one above the other in the saddles, and ring valve actuators in (AS No. 673761, class F 04 F 7/00). The disadvantages of the known vibratory pump are a narrow range of operation and a complex structure.

The purpose of the invention is to expand the functionality by using a vibrating pump as a borehole pump and simplifying the design, increasing the pressure during operation of the pump and the possibility of changing the flow.

The goal is achieved in that the vibration pump is equipped with additional valves located between the main valves, while the pump housing is installed in the well with a gap, the seats of the main valves are made of ferromagnetic material, and the seats of the additional valves are made of non-magnetic material. In addition, the working bodies of all valves are made of non-magnetic material. In the gap between the pump tubes and the vibrating pump, hydraulic connection of the perforated part of the pump tubes to the receiving nozzle of the vibrating pump is provided. The gap provides pre-separation of all oil

volume underneath the inlet pipe. The working elements of all valves are made of non-magnetic material, are mounted on top of each other, which ensures reliable operation and the possibility of increasing the pressure. Stabilization of the depression of the formation is ensured with uniform pumping of oil.

The drawing schematically shows a vibrating pump, a longitudinal section.

Vibration pump. Contains a string of pump pipes and an electric cable 3, mounted on tubing, with an electrical connector. The vibronic pump also contains a cylindrical body 4, ring actuators of valves 5, main valves 6 having seats for working bodies 7, additional valves 8 with seats for working bodies 9, a suction pipe with a seat 10 and a working body 11.

For the manufacture of a vibration pump does not require special equipment since quite simple in design and assembly technology. On the outer surface of the cylindrical casing 4 of the vibration pump, ring electric actuators of valves 5-pulse solenoids are wound. Separate parts of ring electric drives are connected in parallel. Mains power is supplied via electrical cable 3 through an electrical connector. During the operation of the vibrating pump, oil is transported through tubing pipes to the surface to flowing fittings. The control pulses to the ring actuators 5 of the valves b come through a control and monitoring unit mounted on the surface. Ring actuators 5 cooperate with main valves 6, which are capable of reciprocating movement along the axis of the pump. The seats of the main valves are made of ferromagnetic material, and the working parts of the 7 valves are made of non-magnetic material.

. The vibrating pump operates as follows. After the installation is lowered into the well, before it is connected to the network, the vibrating pump is filled with oil (working medium) through the suction pipe with valve seat 10 and working body 11. Oil is transferred from the zone of the working layer - the perforated part of the column pipes 1 to the receiving pipe and then to cavities of the main and additional valves for the working bodies 7. Gas separation through the vibrating pump is hindered by the working body 11, which produce a certain weight, depending on the parameters of a particular well. The pressure of the working medium is generated by a control signal to the ring drives. In the absence of a pulse on the actuator, the main valves return to their original position by the action of their own weight and working medium. Suction and non-return valves hold a column of fluid in the tubing. The uniformity of supply is achieved by the fact that with a certain arrangement of pulsed solenoids and a certain program of control signals, the stroke of one pressure valve 6 can be combined in time with the idle speed of another, or a specific trigger sequence can simply be set.

5 The expansion of functionality is confirmed and characterized by the fact that in the pump zone the oil receives additional heating due to the heat transfer of the drive and especially the heat transfer of the power cable in the zones

0 formation of hydrate-paraffin plugs in tubing. The proposed device, when used in production, makes it possible to stabilize the magnitude of the depression on the formation with uniform pumping of oil and at the same time provides preliminary gas separation. The latter functionality is of great importance for improving oil production compared to other downhole equipment. The technical and economic positive effect of using the proposed device for oil production is due to the expansion of functionality compared to the basic facilities of the downhole equipment.

Thanks to the opportunity to design

and therefore assemble the device

to obtain various fluid pressure

. The proposed technical solution allows to obtain a positive effect.

The proposed new technical solution has significant differences from the known technical solutions, in that a simple constructive use will allow 5 to use the proposed device instead of the basic objects and get a positive economic effect.
