A fixed block 14 arranged above the upper plug 5 is fixed on the inner wall of the well pipe 1, and a spring is arranged between the upper plug 5 and the fixed block 14; the spring provides sufficient downward pressure to move the upper plug 5 downward to compress the rubber particles 7.
A shell 15 with a downward opening is arranged in the middle of the upper plug 5, the opening at the lower end of the shell 15 is fixed on the upper end surface of the upper plug 5, a gap between the upper plug 5 and the monitoring pipe 2 is wrapped in the shell 15, and the contact part of the upper end of the shell 15 and the monitoring pipe 2 is in sliding connection, so that gas in the gas storage chamber is not easy to leak when the gas storage chamber moves up and down; the cavity formed by the shell 15, the upper plug 5 and the monitoring tube 2 is an air storage chamber.
The upper end of the shell 15 is provided with a lower through hole 16, the second one-way valve 8 is arranged below the lower through hole 16, a spring fixed on the upper end face of the shell 15 is arranged above the lower through hole 16, a disc 17 is fixed at the upper end of the spring, a vertical rod 18 is vertically fixed in the middle of the disc 17, the lower end of the vertical rod 18 is arranged in the lower through hole 16, and the vertical rod 18 moves downwards to trigger the second one-way valve 8 to release pressure.

When the device is used, the rubber particles 7 are filled between the upper plug 5 and the lower plug 6 through the feeding device, the spring provides enough downward pressure to enable the upper plug 5 to move downwards to extrude the rubber particles 7, and the rubber particles 7 are mutually extruded to form plugging between the well pipe 1 and the monitoring pipe 2; the device is now in a sealed state.
As time goes on, the rubber particles 7 slowly lose efficacy, the mutual extrusion force among the rubber particles 7 is gradually reduced until air leakage occurs, and air below the lower plug 6 leaks into the space between the upper plug 5 and the lower plug 6 and the air storage chamber; because the cavity below the end cover 3 is low-pressure gas and the gas storage chamber is internally provided with high-pressure gas, the high-pressure gas in the well pipe 1 can drive the gas storage chamber and the upper plug 5 to move upwards against the acting force of the spring at the early stage of gas leakage when the gas leakage is not serious; because only less gas is leaked at the initial stage of gas leakage, the upward movement of the upper plug 5 is slow, the upward movement of the upper plug 5 can reduce the extrusion force among the rubber particles 7, so that the gas leakage is more serious, and a positive feedback effect is formed, once the gas leakage is started, the extrusion force among the rubber particles 7 can be quickly reduced, and the leaked gas can quickly drive the upper plug 5 to move upwards; when the extrusion force among the rubber particles 7 is smaller than the thrust force of the push rod 13, the push rod 13 moves rightwards to extrude the rubber particles 7 through the piston 12, so that new rubber particles 7 enter the well pipe 1 between the upper plug 5 and the lower plug 6;
because the monitoring pipe 2 needs to adjust the position by moving up and down, a gap between the monitoring pipe 2 and the inner edge of the upper plug 5 is larger, a gap between the outer edge of the upper plug 5 and the well pipe 1 is smaller, in the initial air leakage process, air leaked from the outer edge of the upper plug 5 is decompressed through the first one-way valve 4, the pressure in the cavity below the end cover 3 does not change greatly, high-pressure air mainly leaks into the shell 15 through the gap of the inner edge of the upper plug 5, and therefore the high-pressure air can push the upper plug 5 and the shell 15 to move upwards;
in the upward movement process of the shell 15, when the upper end of the vertical rod 18 is in contact with the lower end face of the end cover 3, the vertical rod 18 does not move upward any more, the shell 15 continues to move upward, the lower end of the vertical rod 18 triggers the second one-way valve 8 to release pressure, so that gas in the gas storage chamber leaks into the cavity below the end cover 3, at the moment, the first one-way valve 4 is opened to release pressure, but the pressure release of the first one-way valve 4 is slow, at the moment, the gas pressures in the cavity below the end cover 3, the gas storage chamber and the well pipe 1 are almost the same, under the action of the spring, the upper plug 5 moves downward to apply pressure to the rubber particles 7, so that the pressure between the rubber particles 7 is gradually increased, and the well pipe 1 and the monitoring pipe 2 between the upper plug 5 and the lower plug 6 are plugged again;
when the upper plug 5 moves downwards, the shell 15 also moves downwards, when the vertical rod 18 is separated from the end cover 3, the second one-way valve 8 stops releasing pressure to enable high-pressure air to be reserved in the air storage chamber, the first one-way valve 4 slowly releases pressure, the air enters the monitoring pipe 2 through the air pipe 20 to be recycled, and the first one-way valve 4 can prevent the air in the monitoring pipe 2 from entering a cavity below the end cover 3;
by adding the new rubber particles 7 between the upper and lower plugs 6, the spring is also in a compressed state, so that air leakage can be effectively and automatically found at the initial stage of air leakage, the well pipe 1 can be automatically and effectively plugged, and the sealing aging is effectively prolonged; after the rubber particles 7 lose effectiveness again to cause air leakage, new rubber particles 7 can be repeatedly added, and the sealing aging is effectively prolonged.
The upper plug 5 capable of moving up and down is arranged, a positive feedback effect is formed when the upper plug 5 moves upwards in the initial stage of air leakage, so that the upper plug 5 moves upwards quickly, and then the upper plug 5 moves downwards to form plugging by adding new rubber particles 7; the gas leakage can be automatically found at the initial stage of gas leakage, the well pipe 1 can be automatically and effectively plugged, and the sealing aging can be effectively prolonged.
According to the invention, the feeding device is arranged between the upper plug 5 and the lower plug 6, so that new rubber particles 7 can be repeatedly added after the rubber particles 7 lose effectiveness again to cause air leakage, and the sealing aging is effectively prolonged.
The invention can automatically find the gas leakage and automatically recover the plugging state; the pressure compensation device does not need to be overhauled by workers at regular time and manually.
