Abstract
"DISPOSITIVO DE SONDA PARA UTILIZAçãO EM UMA FERRAMENTA DE INTERIOR DE POçO DISPOSTA EM UM FURO DE POçO CIRCUNDADO POR UMA CAMADA DE FLUIDO CONTAMINADO, E MéTODO PARA AQUISIçãO DE UMA AMOSTRA DE UM FLUIDO VIRGEM DE UMA FORMAçãO SUBTERRáNEA PENETRADA POR UM FURO DE POçO CIRCUNDADO POR UMA CAMADA DE FLUIDO CONTAMINADO". Trata-se de um dispositivo de sonda que realiza amostragens de fluido de um furo de poço que penetra uma formação subterrânea contendo na mesma um fluido virgem localizado após uma camada de fluido contaminado que circunda o furo de poço. O dispositivo de sonda inclui um corpo de sonda passível de extensão a partir de uma ferramenta de interior de poço, e um obturador ('packer') portado pelo corpo de sonda e possuindo uma superfície distal adaptada para estabelecimento de um contato formador de vedação com o furo de poço. O obturador possui uma periferia externa e uma periferia interna, em que a periferia interna é definida por um espaço vazado através do obturador. O obturador é adicionalmente equipado com um ou mais canais formado(s) na superfície distal e dispostos de forma a definirem uma abertura de admissão de limpeza anular entre as periferias interna e externa. A(s) via(s) de passagem estende(m)-se através do obturador para condução de fluido virgem e/ou fluido contaminado entre o(s) canal/canais. Um tubo de amostragem é disposto de forma passível de formação de vedação no espaço vazado do obturador para conduzir fluido virgem para uma segunda abertura de admissão no corpo de sonda e ferramenta de interior de poço.
