Abstract

"MéTODO E APARELHO PARA VARIAçãO DE DENSIDADE DE FLUIDOS DE PERFURAçãO EM APLICAçõES DE PERFURAçãO DE óLEO EM áGUAS PROFUNDAS". São divulgados método e aparelho para controlar a densidade da lama de perfuração de poços em um local no solo oceânico (ou logo acima do solo oceânico) ou abaixo do solo oceânico, em aplicações águas profundas e águas ultraprofundas. Esta invenção combina um fluido-base de densidade inferior à densidade da lama necessário na cabeça do poço para produzir uma lama reduzida no riser. Combinando as quantidades apropriadas de lama de perfuração com o fluido-base, a densidade da lama do riser (coluna de ascensão) na ou próxima à densidade de água do mar pode ser obtida. Esta invenção também inclui um dispositivo de injeção de cabeça do poço para ligar à cabeça do poço e para injetar o fluido-base na lama de perfuração ascendente em um local abaixo do solo oceânico. As linhas de carga do riser são usadas para transportar o fluido-base de baixa densidade para o dispositivo de injeção para injetar na lama de perfuração abaixo do solo oceânico. O refugo é trazido para a superfície com a lama diluída e separado de maneira usual. A lama diluída é passada por um sistema centrifugador para separar a lama de perfuração mais pesada do fluido-base mais leve.
