Abstract
Se da a conocer un método para inhibir la precipitacion del sulfato de bario en fluidos acuosos, con bajo ph, de formaciones subterráneas que llevan petroleo, agregando a estos sistemas una cantidad efectiva de un polímero soluble en agua, de bajo peso molecular, que contiene del 5 al 35 por ciento en peso de unidades de monomeros del ácido sulfonico y del 65 al 95 por ciento en peso de unidades de monomeros del ácido carboxílico. Las composiciones de polímero, basadas en el 10 al 15 por ciento en peso del ácido 2-acrilamido-2-metil-1-propansulfonico, del 15 al 65 por ciento en peso del ácido acrílico y del 25 al 70 por ciento en peso del ácido maléico son particularmente preferidas para su uso en condiciones del ph muy bajas, por ejemplo de 5.5 o menos, en la presencia de concentraciones altas de iones de bario.
