Abstract

Un sistema de perforación de un pozo en una formación subterránea, que incluye: una columna perforadora que se extiende hacia el hoyo de perforación, en el que el espacio anular se forma entre la columna perforadora y la pared del hoyo de perforación, la columna perforadora incluye un ensamblado en el fondo del hoyo y un pasaje de fluido de perforación longitudinal con una apertura de salida en la parte inferior de la columna perforadora; una bomba primaria para bombear selectivamente un fluido de perforación de una fuente de perforación de fluido, a través de dicha columna perforadora y hacia el espacio anular; un conducto de descarga de fluido en comunicación de fluidos con dicho espacio anular para descargar dicho fluido de perforación; un sistema de presión diferencial de fluidos en comunicación de fluidos con dicho conducto de descarga de fluidos, dicho sistema de presión diferencial de fluidos incluye un dispositivo de control de presión diferencial para controlar la presión diferencial en el conducto de descarga para controlar la presión diferencial en el conducto de descarga para aumentar la presión de fluido de perforación en el espacio anular; un sistema de control y de monitoreo de presión programable para controlar dicho sistema de presión diferencial de fluido, el sistema de control y de monitoreo organizado para calcular una presión de fondo del orificio pronosticada utilizando un modelo, dicho sistema de presión diferencial de fluido, comparar la presión del fondo del orificio con una presión del fondo del orificio deseada, y utilizar la diferencia entre estos valores para controlar dicho sistema de presión diferencial de fluido.
