Abstract

"MéTODO E APARELHO PARA CONTROLE DE QUALIDADE DE BOMBEAMENTO ATRAVéS DE TéCNICAS DE ANáLISE DE TAXA DE FORMAçãO". A invenção refere-se a um método e aparelho para a determinação da qualidade de uma amostra de fluido da formação que inclui monitorar a permeabilidade e a mobilidade versus o tempo para determinar um nível de contaminação de filtrado, um estado de fase única sem gás e sólidos no fluido da formação, como este existia na formação e a determinação de fluxo laminar da formação. A presente invenção também permite a determinação de uma taxa de bombeamento ótima para corresponder à capacidade de uma formação de subsuperfície de produzir uma amostra de fluido da formação de fase única em um tempo mínimo. O método e aparelho também detecta os problemas de bombeamento tal como areia e perda de vedação com o furo de poço.
