Abstract

L'invention a trait au forage de puits de pétrole et de gaz. Le procédé consiste à extraire, par séparation, les fractions grossières et fines tirées du matériau isolant, et à colmater successivement les parois du puits présentant ces fractions, selon un traitement par jets provenant d'ajutages. L'invention est notamment applicable à l'isolation, directement pendant le processus de forage, de zones présentant des complications afin d'empêcher l'absorption de boue de forage et de colmatage dans ces zones, et afin d'améliorer l'efficacité fonctionnelle de l'instrument de broyage de roche.
