Abstract
método para mitigar a formação de lama e sistema para mitigar a formação de lama um método e aparelho para mitigar a formação de lama em uma corrente de fluido multifásico que flui através de um conduto sendo que o conduto compreende uma primeira porção e uma segunda porção que está inclinada a montante em relação à primeira porção e em que a corrente de fluido multifásico com prende uma fase gasosa e uma fase líquida, sendo que o método compreende as etapas de:(a)determinar a pressão no conduto a montante de uma zona de injeção de lama; (b) determinar a pressão no conduto a jusante da zona de injeção de lama; (c) determinar a diferença de pressão real ao longo da zona de injeção de lama ao subtrair a pressão a jusante da etapa (b) da pressão a montante da etapa (a); (d) determinar o erro entre a diferença de pressão e a diferença de pressão real; (e) produzir um sinal que compreende um primeiro componente que é proporcional ao erro e um segundo componente que é proporcional à taxa de mudança do erro ao longo do tempo; e (f) usar o sinal produzido na etapa (e) para controlar a posição de uma válvula do afogador ajustável localizada a jusante da zona de injeção de lama de modo a estabilizar o aparecimento de variações na diferença de pressão real ao longo do tempo.
