Title (EN) DOWNHOLE IN-SITU HEAT GENERATION TO REMOVE FILTERCAKE
(FR) GÉNÉRATION DE CHALEUR IN SITU EN FOND DE TROU POUR ÉLIMINER UN GÂTEAU DE FILTRATION
Abstract:
(EN) In a method to degrade filtercake in a hydrocarbon reservoir using downhole in-situ heat generation, a filtercake breaker, configured to degrade filtercake at a temperature, is mixed with a drilling fluid. The drilling fluid mixed with the filtercake breaker is flowed through a hydrocarbon reservoir in which a wellbore is being drilled. A filtercake forms in a portion of the hydrocarbon reservoir responsive to flowing the drilling fluid. A temperature of the portion of the hydrocarbon reservoir is less than the temperature at which the filtercake breaker is configured to degrade filtercake. Multiple filtercake chemicals are flowed to the portion of the hydrocarbon reservoir. The multiple filtercake chemicals, when mixed, are configured to react in an exothermic reaction to release heat to increase the temperature of the portion of the hydrocarbon reservoir to at least the temperature at which the filtercake breaker is configured to degrade filtercake.
(FR) L’invention concerne un procédé permettant la dégradation d’un gâteau de filtration dans un réservoir d'hydrocarbures à l'aide d’une génération de chaleur in situ en fond de trou, un agent de rupture de gâteau de filtration, conçu pour dégrader un gâteau de filtration à une certaine température, étant mélangé à un fluide de forage. Le fluide de forage mélangé avec l’agent de rupture de gâteau de filtration est amené à s’écouler dans un réservoir d'hydrocarbures dans lequel un forage est réalisé. Un gâteau de filtration se forme dans une partie du réservoir d'hydrocarbures en réponse à l'écoulement du fluide de forage. Une température de la partie du réservoir d'hydrocarbures est inférieure à la température à laquelle l’agent de rupture de gâteau de filtration est conçu pour dégrader un gâteau de filtration. Plusieurs produits chimiques de gâteau de filtration s'écoulent vers la partie du réservoir d'hydrocarbures. Les multiples produits chimiques de gâteau de filtration, lorsqu'ils sont mélangés, sont conçus pour réagir dans une réaction exothermique pour libérer de la chaleur afin d’augmenter la température de la partie du réservoir d'hydrocarbures au moins jusqu’à la température à laquelle l’agent de rupture de gâteau de filtration est conçu pour dégrader un gâteau de filtration.
