Abstract

PROCEDIMIENTO DE PREPARACION DE DISPERSANTES PARA LODOS DE PERFORACION. CONSISTENTE EN LA COPOLIMERIZACION DE UNA MEZCLA, EN PROPORCION MOLAR, DE 75% A 99% DE ACIDO ACRILICO O METACRILICO Y DE 1% A 25% DE UNA SAL SOLUBLE EN AGUA DEL ACIDO ALILSULFONICO O METILSULFONICO, ESPECIALMENTE UN ALILSULFONATO O METALILSULFONATO DE SODIO O DE AMONIO. EL CATALIZADOR PUEDE SER AGUA OXIGENADA, EN ASOCIACION CON ALCOHOL ISOPROPILICO EN PRESENCIA DE PEQUEÑAS CANTIDADES DE SAL DE COBRE O SUSTANCIAS ALTERNATIVAS. LA MEZCLA INICIAL INCLUYE, PREFERENTEMENTE, ACIDO ACRILICO Y METACRILICO EN PROPORCION ENTRE 1/1 Y 2/1. EL AGENTE DISPERSANTE SE INCORPORA AL LODO EN CANTIDAD PREFERENTE ENTRE 0,1 G/L Y 0,4 G/L.
