Description

Shooting chaffers for side sampling of rocks are known, containing several sections with barrel holes, gunpowder chambers, connected fire channels and strikers located inside the barrel holes.

The proposed shooting soil for exploration wells of small diameter differs from the known ones by the presence of compensators that are installed in the barrel holes with powder chambers and directed to the opposite side of the barrel holes of the strikers.

The new design of the shooting grounding plate due to the introduction of compensators provides dynamic balancing of its sections and thus eliminates blows against the borehole walls, which prevents from the occurrence of residual bending deformations.

The drawing shows the proposed gruntonos.

It consists of four groups of n-shaped sections / with barrel holes 2, inside of which there are strikers 3 with rubber rings 4 for sealing and compensators 5, made in the form of metal discs.

outlets or paronitic gaskets 7 on the side of the cap holes 2 and are interconnected by two-millimeter fire-conduit channels 8 passing into the incendiary heads 9 with squibs W connected by electric wires // with four-position diode switch 12.

The diode switch 12 has two pairs of diode junctions 13 placed in separate

cavity, and connected to the two conductive wires of the cable 14. The third conductor 15 is used to power the probe, simultaneously descending from the submersible into the well to bind the latter to a certain

productive plastal. Cable 14 Passes through bushing tip 16.

The mutual arrangement of the sections is fixed by screws 17 so that all the strikers 5 are directed to one side, and the sealing

 they are provided with rings 18.

Each section is provided with holes for force 19, which are cut off when firing strikers 3 and compensators 5, and are designed to increase the working pressure of the powder gases during the operation of charges 20.

Shooting submersible works as follows.

From the earth's surface, through the two conductor wires of the cable 14, an electrical pulse is applied to the diode switch 12.

Each section is triggered by one incendiary head 9, and since the powder chambers 6 are interconnected by igniter channels 8, then all the powder charges 20 through them ignite.

Shots from all barrels occur quickly and alternately, one after the other, with compensators 5 being fired in the direction opposite to the flight of the strikers 3.

After the shooting of the submersible, the strikers 3 hang on the cable, located below the tip 21, which increases its permeability when removed from the well.

Separate-group actuation of sections through a diode switch allows to increase the productivity of work with the submersible, so that in one run into the well: well, at the same time, 12 sections are lowered (36 strikers).

Subject invention

Shooting submersible, including sections with barrel holes, roch chambers, connected fire channels and strikers located inside the barrel holes, characterized in that, in order to ensure dynamic balance of the sections and prevent the possibility of residual bending deformations, it is equipped with compensators installed in the barrel holes, directed in the direction opposite to the barrel holes of the heads.
