Title (EN) VISCOSIFIED FLUID LOSS CONTROL AGENT UTILIZING CHELATES
(FR) AGENT DE RÉGULATION DE PERTE DE FLUIDE À INDICE DE VISCOSITÉ AMÉLIORÉ UTILISANT DES CHÉLATES
Abstract: front page image
(EN)Disclosed herein is a well treatment method comprising the steps of injecting into a well a fluid loss control agent comprising a chelating agent, a viscosity increasing agent, and a plurality of at least partially insoluble bridging solid particles dispersed therein, wherein the chelating agent is effective to at least partially solubilize at least a portion of the bridging solid particles over a solubilizing period of time for thereafter substantially dissolving the bridging solid particles, wherein the solubilizing period of time is controlled by the concentration of the viscosity increasing agent, the concentration of the chelating agent, the composition of the metal salt, the pH of the fluid loss control agent, or a combination thereof. A fluid loss control agent is also disclosed.
(FR)L'invention concerne un procédé de traitement de puits consistant à injecter dans un puits un agent de régulation de perte de fluide comprenant un agent de chélation, un agent d'augmentation de la viscosité, et plusieurs particules solides de pontage au moins partiellement insolubles, dispersées dans l'agent de régulation de perte de fluide. L'agent de chélation peut solubiliser efficacement au moins une partie des particules solides de pontage, sur une durée de solubilisation, puis dissoudre sensiblement les particules solides de pontage. La durée de solubilisation est contrôlée par la concentration de l'agent d'augmentation de viscosité, la concentration de l'agent de chélation, la composition du sel métallique, le pH de l'agent de régulation de perte de fluide, ou une combinaison de ceux-ci. L'invention concerne en outre un agent de régulation de perte de fluide.
