An oil and gas well shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (2), a high explosive (3), and a reactive liner (6) where the high explosive (3) is positioned between the reactive liner (6) and the housing (2). The reactive liner (6) is produced from a composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition may be selected from any known formulation which is suitable for use in an oil and gas well perforator, typically the composition will comprise at least two metals such as to form a inter-metallic as classified by Hume-Rothery electron compounds and at least one further metal, which is not capable of an exothermic reaction with the reactive composition which is present in an amount greater than 10% w/w of the liner (6).

L'invention concerne un perforateur de charge façonné de puits de pétrole et de gaz, capable de fournir une réaction exothermique après une détonation, le perforateur comprenant un boîtier (2), un explosif détonant (3) et un revêtement interne réactif (6), l'explosif détonant (3) étant positionné entre le revêtement interne réactif (6) et le boîtier (2). Le revêtement interne réactif (6) est produit à partir d'une position qui est capable de supporter une réaction exothermique pendant la formation du jet de coupe. La composition peut être choisie à partir de toute formulation connue qui est appropriée pour une utilisation dans un perforateur de puits de pétrole et de gaz. Typiquement, la composition comprendra au moins deux métaux tels qu'ils forment un composé intermétallique tel que classifié par les composés d'électron Hume-Rothery et au moins un autre métal, qui n'est pas capable d'une réaction exothermique avec la composition réactive qui est présente dans une quantité supérieure à 10 % en poids du revêtement interne (6).
