Abstract

Se proporcionan un método y aparato para determinar un nivel de fluido y/o flujo de salida durante la operación de una bomba centrífuga, que se pueden usar para la producción de gas y/o petróleo desde una perforación, e incluyen un modelo de retroalimentación de vector para derivar valores del momento torsor y de la velocidad a partir de señales indicativas de corriente y voltaje instantáneos consumidos por el motor de la bomba, un modelo de bomba que deriva valores de la velocidad de flujo de fluido y de la presión de cabezal para la bomba a partir de la entradas del momento torsor y velocidad, un modelo de sistema de bombeo que deriva, a partir los valores estimados de los parámetros de operación de la bomba, un valor estimado del nivel de fluido y otros parámetros del sistema de bombeo. Controladores sensibles a los valores estimados de los parámetros del sistema de bombeo controlan la bomba para mantener el nivel de fluido en la entrada de la bomba, cerca de un nivel óptimo, o dentro de un intervalo de operación segura y/o de flujo de salida de la bomba.
