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.
