Abstract: A method of controlling the annular pressure in a well during a well construction operation. The operation comprises pumping a fluid down a tubing located within the well and extracting the fluid that flows back through an annulus within said well and surrounding the tubing. The method comprises defining a set pressure pref, determining a desired extraction flow rate qc of fluid from said annulus in dependence upon the set pressure pref and a pumped flow rate into the annulus, and configuring an extraction path to achieve said desired extraction flow rate.

Abstract: Se describe un método para controlar la presión anular en un pozo durante una operación de construcción de pozo. La operación comprende bombear un fluido hacia abajo de una tubería ubicada dentro del pozo y que extrae el fluido que fluye a través de un anillo dentro de dicho pozo y rodea la tubería. El método comprende definir una presión de regulación, Pref, determinando una velocidad de flujo de extracción deseada, qç, del fluido desde dicho anillo en dependencia de la presión de regulación y una velocidad de flujo bombeado hacia el anillo, y configurando una trayectoria de extracción para lograr la velocidad de flujo de extracción deseada.
