Title (EN) COLLAPSE INITIATED EXPLOSIVE PELLET
(FR) PASTILLE EXPLOSIVE AMORCÉE PAR ÉCRASEMENT
Abstract: front page image
(EN)A technique facilitates analysis of hydraulic fractures. A plurality of explosive pellets is constructed for delivery into a fracture or fractures of a subterranean formation. Each explosive pellet comprises an explosive material combined with an initiating member working in cooperation with a friction sensitive pyrotechnic mixture. Crushing or otherwise actuating the initiating member initiates the friction sensitive pyrotechnic mixture which, in turn, ignites the explosive material to produce explosive signals. The explosive signals may be monitored to obtain data related to the fracture or fractures.
(FR)L'invention concerne une technique facilitant l'analyse des fractures hydrauliques. Une pluralité de pastilles explosives est conçue pour être introduite dans une fracture ou dans des fractures d'une formation souterraine. Chaque pastille explosive comprend un matériau explosif combiné à un élément d'amorçage fonctionnant en coopération avec un mélange pyrotechnique sensible au frottement. L'écrasement ou ou autre actionnement de l'élément d'amorçage amorce le mélange pyrotechnique sensible au frottement qui, à son tour, allume le matériau explosif pour produire des signaux d'explosion. Il est possible de surveiller les signaux d'explosion pour obtenir des données relatives à la fracture ou aux fractures.
