Abstract

"MéTODO E APARELHO PARA EXECUTAR UM PRé-TESTE NUMA FORMAçãO DE ROCHA PERMEáVEL". A presente invenção está voltada para métodos e aparelhos para usar um testador de formação que possui baixa permeabilidade, coletando intermitentemente uma parte de fluido a uma taxa de rebaixamento de nível constante. A pressão de rebaixamento de nível é monitorada até que um diferencial de pressão máximo seja alcançado entre a formação e o testador. A seguir, o pistão é parado até que o diferencial de pressão aumente até um valor estabelecido, quando então o pistão é reiniciado. A operação intermitente controlada do pistão continua até que seja alcançado um volume de pré-teste estabelecido. O rebaixamento de nível modulado permite uma coleta precisa de dados de pressão em relação ao tempo que são em seguida usados para calcular a pressão de formação e permeabilidade. A presente invenção também pode ser usada em aplicações de registro de sondagem durante a perfuração e de medição durante a perfuração nas quais a conservação de potência é crítica.
