- the fluid After the end of the burning process, the fluid will move further when the inertia forces are in motion.
- the pressure in the gas supply will be less than the pressure of the fluid stop and it will start to move down.
- the pressure in the gas discharge due to gas compression will increase and, at the same time, the full consumption of liquid energy will increase the pressure of the fluid.
- the equipment for the implementation of this method consumes the charged charges installed on the mainstream devices.
- the device is equipped with a flash ignition system, installed in a pressurized cavity and incorporating a quick ignition device and a remote control unit. The device operates the following way. When delivering an electrical pulse from an explosive ⁇ ⁇ 97/08427 ⁇ / ⁇ 5 / 00183
- the proposed method makes it possible to substantially increase the time of exposure to excessive pressure on the casual zone of the area.
- the product is designed to save energy and planting in a healthy place. Subsequent pulsed pressure influences a more significant process of production and, thereby, increases the efficiency of the product and the failure.

- the method of working on a free-standing zone of a meal involves, in addition, creating excessive pressure in the well through the use of a gas-processing facility. Excessive pressure builds up at least two pressure pulses. The amplitude and duration of the first impulse are chosen to be sufficient for the expansion of natural and the emergence of new microcracks in the area. The amplitude and duration of the second pulse selects the same amplitude and the duration of the pulse to develop these gaps.

- Disposal products 8 of the igniter discharges the heat exchanger 2 and burns the discharge I.
- the pressure generated in the bore depends on the amount of gas produced by the charge I per unit of time, and the pressure build-up depends on the mass of the charge I during section 7.
- the primary combustion section 7 (that is, the positive pressure pulse) must be selected so that ⁇ ⁇ 97/08427 ⁇ / ⁇ 95 / 00183
- the pressure in the borehole drops and at the end of the end of the combustion of the first section 7, the pressure value is equal to 0.5 times the total pressure of 8.

Abstract
La présente invention concerne des procédés de stimulation de puits de forage et consiste à créer une pression excédentaire dans le puits en exerçant sur le lit une action par impulsion à l'aide de produits de combustion gazeux générés par une charge de poudre explosive. Les paramètres de la première impulsion sont choisis de manière à provoquer l'ouverture des fissures naturelles et la création de microfissures, les paramètres des impulsions suivantes étant au moins égaux à ceux de la première impulsion. Le dispositif permettant de mettre en oeuvre ce procédé comprend des charges de poudre explosive (1) disposées dans des tubes (2) qui sont reliés entre eux de manière à créer des cavités étanches (4). Chaque cavité (4) est divisée en plusieurs sections (7) par des cloisons (6) faites d'une composition pyrotechnique. Chaque section (7) contient au moins une charge (1) et un détonateur de mise à feu (8). La section supérieure (7) renferme une cartouche pyrotechnique (10) connectée à un mécanisme explosif. Cette invention peut être utilisée afin d'accroître le rendement de puits de pétrole et de gaz dont les lits de production possèdent de faibles caractéristiques de volume de filtrage.
