Description

The invention relates to mining and can be used in the well extraction of solid minerals.

The aim of the invention is the elimination of the unproductive consumption of a pressurized working agent.

Figo 1 and the diagrams of the unit are shown at different positions of the jetting column.

The well hydromonitor assembly contains a central pulping column 1, a pressure hydraulic elevator column 2, a pressure hydraulic column 3, a bumper nozzle 4, a hydraulic elevator with a perforated wall 5 of the receiving chamber 6 and a nozzle 7, a connector 8, a channel 9, a seal, a seal, a seal 5 of the receiving chamber 6 and a nozzle 7, a port 8, a channel 9, a seal, a seal, a seal 5 of the receiving chamber 6 and a nozzle 7, a port 8, a channel 9, a seal, a seal, a seal 5, a chamber 6 and a nozzle 7, a seal 8, channel 9, sealed eleven.

The pressurized hydraulic elevator column 2 is located concentrically with the pulp of the concave 1 and is rigidly connected with it, while the hydraulic elevator column can reach the surface and communicate with the independent pump, and on the other hand can be connected to the jetting column through openings 12c.

The pressurized hydraulic column is mounted concentrically to the hydraulic-elevator 2 with the possibility of rotation and axial movement relative to the last deadline. The end cap 4 is in communication with the hydraulic column, and the adapter can be placed both inside and outside the column cavity. The hydraulic elevator pump 7 is in communication with the hydraulic elevator pipe 1 crossing the receiving chamber.

The nozzle 8 is mounted in the jetting column at its downhole end with a concentric hydraulic elevator column and rigidly connected to the jetting column. The wall of the nozzle is made with two holes 14 and 15 spaced apart along the length of the nozzle, the lower 14 of which are located at the lower end of the nozzle. These holes are interconnected by a channel 9 located in the jet column and insulated from the cavity of the latter. A tube element installed in the cavity between the branch pipe B and the wall of the jet column can be used as a channel.

The hydraulic elevator column on the outer side of the receiving chamber is complete

with a groove 16 and a hole 17 located in the interval of the groove at its lower end. The valve 11 is installed in the said opening in such a manner 5 that when it is pressed from the outside of the hydraulic elevator column it opens. As a valve, known check valves can be used. Seals 10 are installed on the hydraulic elevator column above and below the groove with the possibility of contact with the nozzle 8, while the lower seal is located between the groove 16 and the receiving chamber 6c

The length of the groove and the distance between the holes 14 and 15 exceed the length of the perforation of the receiving chamber, while the length of the groove and the specified distance are chosen so that when the lower hole 14 is located within the perforation of the receiving chamber, the upper hole 15 is located within the groove interval.

The outer diameter of the receiving chamber is smaller than the outer diameter of the hydro-elevator column.

The unit works as follows. After conducting a pilot well to the soil of the productive horizon with re-drilling, an aggregate is placed in it, while the jetting column is installed in the uppermost position. Hydro-monitor and hydro-elevator columns are fed under pressure, which, passing the nozzle 4 and 7, is formed in a jet, ensuring the destruction of the rock and hydrotransport of the pulp to the surface using a pulp production column. When the hydraulic column is rotated, a excavation chamber is formed. As the hydraulic column is softened, the productive column is removed at full capacity, while the upper seal 10 and the valve 11, which is in the closed position, prevent leakage of pressurized fluid.

When fixing the perforation or cavity of the receiving chamber, as well as, if necessary, the destruction of oversize accumulated at the receiving windows, lowering of the jetting column is carried out. As soon as the bottom end

pipe 8 presses valve 11, pressure fluid begins to flow into the gap between groove 16 and pipe 8 from the hydraulic elevator column.

Through the hole 15, the channel 9 and the hole 14, the liquid in the jet stream is directed to the receiving windows and into the cavity of the receiving chamber, unstitched, and the hydraulic elevator column is rotated and descended into within the interval of the receiving chamber. At the same time, the destruction of oversize by the fender attachment 4 is performed. In this case, the lower seal 10

The connection between the groove and the receiving chamber on the hydro-elevator column does not allow

liquids out of the gap between the groove and the nozzle.

After the shirring, the hydraulic column is lifted, and as soon as the nozzle is no longer in contact with the valve, the flow of pressure fluid from the hydraulic elevator column through the opening 17 is stopped, and the rocks continue to wash out

If necessary, cleaning the receiving windows and the cavity of the receiving chamber can be repeated.
