Abstract
"FERRAMENTA DE INTERIOR DE POçO PASSìVEL DE POSICIONAMENTO NUM FURO DE POçO CIRCUNDADO POR UMA CAMADA DE FLUIDO CONTAMINADO E MéTODO PARA AMOSTRAGEM DE FLUIDO VIRGEM DE UMA FORMAçãO SUBTERRâNEA PENETRADA POR UM FURO DE POçO CIRCUNDADO POR FLUIDO CONTAMINADO". São revelados um aparelho e um método para extração de fluido de uma formação subterrânea. Uma ferramenta de amostragem de interior de poço é provida com uma sonda possuindo uma parede interna capaz de desviar seletivamente fluidos virgens para o interior de um ou mais condutos de fluxo virgem para amostragem, simultaneamente desviando fluidos contaminados para o interior de um ou mais condutos de fluxo contaminado para serem descartados. As características do fluido que passa através dos condutos da sonda podem igualmente ser medidas mediante utilização de técnicas tais como de densidade ótica, para avaliação de diversos parâmetros de fluido, tais como níveis de contaminação. Os dados gerados durante a amostragem podem ser enviados para um dispositivo controlador capaz de gerar dados, comunicar e/ou enviar sinais de comando. O fluxo de fluido para dentro da ferramenta de interior de poço pode ser seletivamente ajustado para otimização do fluxo de fluido para o interior dos condutos mediante ajuste da parede interna contida na sonda e/ou mediante ajuste das taxas de fluxo através dos condutos. A configuração da parede interna e/ou das taxas de fluxo pode (m) ser automaticamente ajustada (s) pelo dispositivo controlador e/ou manualmente manipulada (s) para otimização adicional do fluxo de fluido.
