Abstract

PROCESSO PARA REDUZIR A PRESSãO DE REINICIO DE CORRENTES, E, MéTODO PARA MEDIR OS PERFIS DO DIáMETRO INTERNO DE UMA TUBULAçãO E A VISCOSIDADE INSTANTáNEA DO FLUIDO CONTIDO NELA é descrito um processo para a redução da pressão de reinício de correntes selecionadas de óleos brutos cerosos, emulsões de água em óleo bruto e dispersões de hidratos de hidrocarboneto, pelo menos parcialmente estruturado, caracterizado pelo fato um distúrbio mecânico é aplicado, em condições de parada de fluxo, em ditas correntes, tendo: -temperaturas mais baixas do que a WAT (Temperatura de Aparência Cerosa) para os óleos brutos cerosos e emulsões de água em óleo bruto; - temperaturas mais baixas do que as temperaturas de formação de ditos hidratos e pressões mais elevadas do que a pressão de formação de ditos hidratos, para as dispersões de hidratos de hidrocarboneto. Além disso, é descrito um método para medir o diâmetro interno de uma tubulação e a viscosidade instantânea do fluido nele contido, caracterizado pelo fato de que é executado mediante a geração de ondas sonoras e de infra-som que são geradas, sob as condições de ausência de fluxo, por meio da vazão rápido transitória, subseqüentemente registrada por um dispositivo de medição adequado e processada, assim obtendo o perfil do diâmetro interno do duto e a viscosidade instantânea do fluido nele contido.
