Abstract

"PROCESSOS PARA PERFURAR UM POçO E PARA PERFURAR E TRATAR UM POçO E FLUIDO PARA PERFURAR E TRATAR UM POçO". A invenção proporciona um processo e um fluido para perfuração ou de serviço de um poço em uma formação subterrânea contendo zonas de circulação perdidas ou reservatórios de baixa pressão, esgotados. Um processo de diminuição da densidade do fluido circulado em um furo de perfuração, de diminuição da invasão de fluido para dentro de formações contactadas pelo fluido, ou de diminuição do potencial de circulação perdida de fluido é proporcionado pelo uso, como o fluido, de um líquido aquoso possuindo dispersado dentro dele um polímero que aumenta a viscosidade de baixa taxa de cisalhamento do fluido em uma extensão que o índice de redução de cisalhamento do fluido seja de pelo menos cerca de 10, um agente tensoativo, e aphrons, no qual os aphrons são preferivelmente gerados pela turbulência e pela queda de pressão à medida que o fluido sai da broca na vizinhança da formação, o fluido possuindo uma viscosidade de baixa taxa de cisalhamento de pelo menos 10.000 mPa.s. O fluido contém adicionalmente uma mistura de oligossacarídeos composta de pentosanas e/ou de hexosanas contendo de uma a cerca de 10 unidades de açúcar combinadas selecionadas do grupo consistindo de arabinose, manose, galactose, glicose, xilose, celobiose, e misturas das mesmas. Preferivelmente, a mistura de oligossacarídeos é a porção solúvel em água de lignocelulose termicamente hidrolisada.
