Abstract

"CONCENTRADOS DE POLìMEROS HIDRóFILOS". A invenção refere-se a um concentrado de polímero hidrófilo solúvel em água para adição a líquidos aquosos para acentuar as propriedades do mesmo, particularmente para aumentar a viscosidade ou diminuir a perda de fluidos de perfuração e manutenção de poços, concentrado este que compreende um líquido hidrofóbico insolúvel em água, um agente de suspensão de argila organófila, o polímero solúvel em água, e um agente de estabilização que compreende um ou mais ácidos em uma quantidade de cerca de 0,001% a cerca de 1,5%, um ou mais tensoativos aniónicos em uma quantidade de cerca de 0,001 % a cerca de 1,0%, um ou mais tensoativos não-iónicos em uma quantidade de 0,001% a cerca de 0,625% e, de cerca de 0% a cerca de 0,75% de um ou mais líquidos orgânicos solúveis em água, em que a concentração total do agente de estabilização é de cerca de 0,1% a cerca de 2,5%, sendo essas porcentagens baseadas no peso do concentrado. Preferencialmente, o agente de estabilização é uma microemulsão que compreende o(s) ácido(s), o(s) tensoativo(s) aniónico(s), o(s) tensoativo(s) não-iónico(s), e o líquido(s) orgânico(s) solúvel(solúveis) em água, e adicionalmente compreendendo de cerca de 0,0005% a cerca de 1,0% de um ou mais solventes insolúveis em água, e de cerca de 0,001% a cerca de 2,0% de água.
