Description

The invention relates to a device for lifting liquids from great depths by transporting materials using hydraulic means and can be used in oil and other industries.

A device is known for hydraulic transportation of materials, containing containers with internal volume dividers made in the form of elastic diaphragms, pipelines with check valves for supplying and discharging the transported medium, and pipelines for supplying and discharging the working component connected to containers on different sides of the separator (autosweet. USSR No. 1652245, IPC ⁷ B65G 53/30, publ. 1991).

Such a device contains two containers installed in parallel, which increases its transverse dimensions and prevents use in places with limited transverse dimensions, for example, in wells.

Closest to the claimed and adopted as a prototype is a device for transporting a fluid (diaphragm displacement pump), containing two bodies with elastic dividers, forming in each case on one side of the tank separator for the transported fluid and on the other side - tanks for the working component , pipelines with non-return valves for supplying and discharging the transported medium and the unit for supplying and discharging the working component for changing the volume of containers (Prospect LLC URALPROMTRA NS "2003).

Such a device is used for oil production in reservoir pressure increasing systems. However, its use in the well is also limited for the reasons described above.

The technical result of the invention is the ability to transport fluid from the well by reducing the transverse dimensions of the device.

The technical result is achieved by improving the device for transporting a fluid, containing two bodies with elastic dividers, forming in each case on one side of the tank separator for the transported fluid and on the other side - tanks for the working component, pipelines with check valves for supplying and discharging the transported environment and node supply and removal of the working component to change the volume of containers.

This improvement consists in the fact that the casings are arranged in series, while the pipeline for removing the transported medium from the first tank has a channel passing through the second housing, and the pipeline for supplying the transported medium to the second tank has a channel passing through the first housing,

In addition, the node for supplying and discharging the working component can be equipped with a tandem cylinder with a rod with pistons dividing the cylinder into four cavities, two of which are connected to the pipelines for supplying and discharging the working component to elastic containers, and the other two are connected to the supply and discharge source of the working component.

The arrangement of the bodies in series allows to reduce the transverse dimensions of the device, which makes it possible to locate it in places with limited transverse dimensions, for example, in a well.

The execution of the pipeline for the removal of the transported medium from the first tank with a channel passing through the second housing, and the pipeline for the supply of the transported medium to the second tank with the channel passing through the first housing, allows you to perform the necessary communications for supplying and discharging the transported medium to the tanks with a sequential arrangement of cases with containers without increasing the transverse dimensions of the device.

Providing a supply unit for supplying and discharging the working component with a tandem cylinder with a piston rod that divides the cylinder into four cavities, two of which are connected to pipelines for supplying and discharging the working component to elastic containers, and the other two are connected to the supply and discharge source of the working component — rational and reliable option for supplying a working component to change the volume of elastic containers.

The invention is illustrated in the drawing, which schematically shows the proposed device installed in the casing in the well.

The device for transporting a fluid contains two housings 1 and 2 arranged in series with elastic dividers 3 and 4, forming in the housings 1 and 2 on one side of the separator a first container 5 and a second container 6 for the transported fluid and on the other side of the separators 3 and 4 - containers 7 and 8 for the working component, pipelines 9 and 10 with non-return valves 11 and 12, respectively, for supplying the transported medium, and pipelines 13 and 14 with non-return valves 15 and 16 for discharging the transported medium. The pipeline 10 for supplying the transported medium to the second tank 6 has a channel 17 passing through the housing 1. The pipe 13 for removing the transported medium from the first tank 5 has a channel 18 passing through the housing 2. The node for supplying and discharging the working component in the above embodiment is filled working fluid (for example, oil) with a tandem cylinder 19, with a rod 20 with pistons 21 and 22, dividing the cylinder 20 into four cavities 23, 24, 25 and 26. The cavities 23 and 26 are connected by pipelines 27 and 28 with capacities 8 and 7, and cavities 24 and 25 are connected by pipelines 29 and 30 with a source of supply and discharge of the working component located on the surface (not shown).

The device operates as follows.

The device for transporting the fluid is located in the well at the depth of the oil layer, which is connected through the filter 31 to the pipelines 9 and 10. In the initial position (shown in the drawing), the first tank 5 is filled with the transported medium - oil. From a source located on a surface (not shown), the working component is piped through 29 to the cavity 24 of the tandem cylinder 19. In this case, the piston 21 and the associated piston 22 are moved downward, displacing the working component from the cavity 23 through the pipeline 27 to the container 7, which in this case increases in volume displaces the oil from the tank 5 through the channel 18 into the pipeline 13. Under the action of the oil flow, a check valve 15 opens, through which oil is supplied through a pipe (not shown) to the surface. When the piston 22 moves down with it, the rod 20 and the piston 21 move down, increasing the volume of the cavity 26 into which the working component is sucked from the container 8. The volume of the container 8 decreases, deforming the separator 4 and increasing the volume of the container 6. Under the action of the generated in the container 6 the vacuum opens the check valve 12 and the oil through the channel 17 enters the tank 6. When moving down the rod 20, the working component is displaced from the cavity 25 through the pipe 30 to the drain. When the pistons 21 and 22 reach the lowest position, the flow is switched over, and the working component is piped 30 into the cavity 25 of the tandem cylinder 19, providing upward movement of the rod 20 and the pistons 21. When this happens, the tank 5 is filled with oil through the open check valve 11 through the pipeline 9 and the oil is displaced from the tank 6 through the pipe 14 through the open valve 16. When the pistons 21 and 22 reach the highest position, the device’s cycle is repeated, while the oil is constantly supplied to surface.

Thus, the use of the proposed device provides the ability to transport fluid from the well by reducing the transverse dimensions of the device and the possibility of placing it in the well.
