Abstract

Se expone un fluido para perforar con base acuosa para utilizarse en la perforacion de pozos a traves de una formacion que contiene un esquisto que aumenta de volumen en presencia de agua. De preferencia, el fluido para perforar incluye: una fase continua con base acuosa, un material de ponderacion y un agente inhibidor de hidratacion de un esquisto que tiene la formula: H2N-CH (CH3) CH2{-OCH2CH (CH3)-}x-NH2 en la cual x tiene un valor menor a 15. El agente inhibidor de hidratacion de un esquisto podria estar presente en una concentracion suficiente para reducir el aumento de volumen del esquisto. De preferencia x tiene un numero promedio entre aproximadamente 1 y 5, y con mayor preferencia x tiene un numero promedio de aproximadamente 2.6. Tambien se incluye en la presente invencion un metodo para reducir el aumento de volumen del la arcilla del esquisto encontrada durante la perforacion de un pozo subterraneo, el metodo comprende hacer circular en el pozo un fluido para perforar con base acuosa preparado de acuerdo con la presente invencion.
