Abstract

Un fluido a base de agua para el uso en pozos de perforación y otras operaciones de perforación que incluye arcilla esquistosa la cual se engrosa en la presencia del agua. Preferentemente, el fluido incluye, una fase continua de base acuosa y un agente de inhibición de hidratación de arcilla esquistosa que tiene la fórmula: H-(OR)x-[-NH-CH2-CH2-CH2-O-CH2-CH2-NH-]-(R'O)y-H, donde R y R' son grupos alquilenos seleccionados independientemente teniendo de 2 a 4 átomos de carbono y donde x y y tienen valores independientemente seleccionados tales que la suma de x y y sea por lo menos de 1. El agente de inhibición de hidratación de arcilla esquistosa debe estar presente en una concentración suficiente para reducir la intumescencia de la arcilla esquistosa. El fluido puede ser usado para formular fluidos de perforación tales como los lodos de perforación a base de agua o fluidos de perforación de salmuera clara. El fluido también puede ser usado en la mezcla y eliminación de ripio que contiene arcilla que se engrosa en el agua o arcilla esquistosa.
