Abstract

The invention relates to the drilling of wells in a rotary percussion method. The goal is to increase work efficiency by improving unloading conditions. The slurry receiver includes a drill pipe, on which the bottom 2 with a groove is mounted concentrically and the slurry reception pipe is made of sections (C) 3. C 3 3 are placed one above the other with the possibility of axial movement. The lower parts of the C 3 are made with a tapered bore, and the upper parts with an outer conical end. The bottom 2 is rigidly fixed on the drill pipe 2 by the lock 4 and has a conical outer surface placed in the corresponding conical opening of the lower C with the possibility of its axial movement. When drilling, due to the fact that the landing is made in the form of self-braking conical surfaces, the vibrations of the drill string and the impact hammer do not cause a violation of the integrity of the sludge receiver. If there is still some displacement between the individual C, the conical surfaces serve as guides along which C 3 return to their place. 1 il.

FIELD OF THE INVENTION The invention relates to mining, in particular to the drilling of wells in a rotary percussion method.

The purpose of the invention is to increase work efficiency by improving unloading conditions.

The drawing shows the device, the overall appearance.

The sludge collector consists of a drill pipe 1, on which the bottom 2 with the projecter is concentrically mounted, and the shield-receiver pipe is made of sections 3. The latter are placed one above the other with the possibility of axial movement, the lower parts of sections 3 are made with a tapered bore, with outer conical end. The bottom 2 is rigidly fixed on the drill pipe 1 by the lock 4 and has a conical outer surface, the plug is placed in the corresponding conical fitting hole of the lower section with the possibility of its axial movement. Shlampriemnik works as follows.

Before descending into the well, the bottom 2 is lowered onto the lock 4. The lower section 3 is lowered onto its outer conical surface. Then the next section is placed on the upper part 3, etc. Further in the well, the Shlampriemnik is placed above the pneumatic (hydro) drummer. When drilling, due to the fact that the landing is made in the form of self-braking conical surfaces, vib15

Nicknames do not cause violations of the integrity of the sludge receiver. If, however, a certain shift occurs between the separated sections, the conical surfaces serve as guides, along which section 3 returns to its distance. After lifting, the drill pipe is placed on supports in such a way that it assumes a horizontal position. To remove the slurry of section 3, starting from the top, move it away from the rest of the piece and empty it with short reciprocating movements carried out with pressure on the drill pipe 1. The process of unloading the sludge pipe is facilitated and also appears with the possibility of layer-by-layer divided slurry sample.

Claims (1)

Claims of sludge receptacle, including a drill pipe, concentrically mounted sections of a slurry receiving pipe with the possibility of reciprocal axial movement, on a bottom rigidly fixed on the drill pipe, characterized in that, in order to expand technological capabilities, the sections of the slurry pipe are connected conical, while the lower parts of the sections are made with conical fitting holes and the upper with outer conical ends, and the bottom is made with an outer conical surface and set Leno in a tapered bore with the possibility of axial ne radios of the drill string and pneumatic impact-50 displacement section.

If a certain shift occurs between the individual C, the conical surfaces serve as guides on which the C 3 return to their place. 1 il. five nicknames do not violate the integrity of the sludge collector. If there is still some shift between the individual sections, the conical surfaces serve as guides, in which section 3 returns to its place. After lifting, the drill pipe 1 is placed on the supports so that it takes a horizontal position. To remove the sludge section 3, starting from the top, move away from the rest and empty with short reciprocating movements carried out with pressure on the drill pipe 1. The process of unloading the sludge pipe is facilitated, and also the slurry sample can be separated. Invention Slamp acceptor, including a drill pipe, concentrically mounted sections of a slurry receiving pipe with the possibility of reciprocal axial movement, on the bottom rigidly mounted on the drill pipe, characterized in that, in order to expand technological capabilities, the connection of sections of the slurry receiving pipe is made conical, the lower parts of the sections are made with conical bore holes, and the upper parts are with external conical ends, the bottom being made with an external conical surface and mouth Anchored in a conical bore with the possibility of axial movement of the section.
