Abstract

<B>"PROCESSO PARA A AVALIAçãO DE FLUIDOS DE PERFURAçãO é descrito um processo para a avaliação de fluidos de perfuração a serem usados com rochas ricas em argilas tais como folhelhos, o processo compreendendo coletar os folhelhos de modo a preservar a condição de hidratação de fundo de poço e então submeter esse folhelho preservado a Análise Termo-Gravimétrica, de modo a obter a curva derivada da massa em relação à temperatura, depois imergir uma amostra do mesmo bloco de rocha no fluido de perfuração para o qual a interação com a rocha rica em argila deve ser determinada e obter análise TGA em intervalos de tempo sucessivos de imersão da amostra, de modo a determinar as modificações sofridas pela amostra imersa no fluido de perfuração. A partir das modificações sofridas pela amostra é possível avaliar a adequação do fluido de perfuração a ser colocado em contato com a rocha rica em argila.
