Abstract
<B><MU>FLUIDO DE PERFURAçãO DE SALMOURA TRANSPARENTE<MV><D>. São revelados um fluido de perfuração compreendendo uma mistura de salmoura e aditivos para manter propriedades reológicas em uma salmoura neutra ou ligeiramente ácida e um método para usar o fluido de perfuração para sondar uma formação de produção. O fluido de perfuração compreende polímero viscoso e polímero de perda de fluido que funciona na salmoura sem afetar substancialmente adversamente as suas propriedades. A salmoura é substancialmente isenta de sólidos insolúveis. O polímero viscoso e/ou o polímero de controle de perda de fluido podem ser solúveis em ácido. Sais de zinco na forma de brometo de zinco isolado ou em uma mistura de brometo de zinco e brometo de cálcio são adicionados para aumentar a densidade da solução de salmoura. O polímero viscoso tem amido suspenso e ácido sulfónico ou grupos sulfonados. Alternativamente ou adicionalmente, o polímero viscoso compreende um polissacarídeo. O polímero de controle de perda de fluido pode compreender um amido de ligação cruzada, catiónico ou anfotérico. Sólidos solúveis são dispersos na salmoura.
