Abstract

En anordning for redusering av etterdetonasjonstrykk i en perforeringskanon, hvilken anordning inkluderer en perforeringskanon som bærer minst én eksplosiv ladning, hvor når den eksplosive ladning detoneres, den eksplosive ladning frembringer en trykksatt detonasjonsgass, og en mekanisme for redusering av trykket i detonasjonsgassen nær perforeringskanonen. Detonasjonsgassens trykk reduseres ønskelig i en tidsramme som er tilstrekkelig til å danne en dynamisk underbalansetilstand for å fremme en bølgestrømning av fluid fra et reservoar inn i en brønnboring. Trykkreduksjonsmekanismen kan inkludere det ene av eller en kombinasjon av et kjølelegeme (16) for å redusere temperaturen i detonasjonsgassen, en reaktant for å rekombineres med reaktantgassen og redusere den molare tetthet i detonasjonsgassen, og en fysisk kompresjonsmekanisme for å benytte avfallsenergien i detonasjonsgassen til å frembringe arbeid, hvilket samtidig reduserer temperaturen i gassen og den molare tetthet i detonasjonsgassen.
