The system monitors the operating pressures within a tubular member (18) and compares the actual operating pressure with a desired operating pressure. The difference between the actual and desired operating pressure is then processed to control the operation of an automatic choke (102) to thereby controllably bleed pressurized fluidic materials out of the annulus (24) between the tubuolar member (18) and the borehole (12) thereby creating back pressure within the borehole.

L'invention concerne un système permettant de contrôler la pression d'exploitation à l'intérieur d'un élément tubulaire (18) et de comparer la pression d'exploitation effective avec une pression d'exploitation souhaitée. La différence entre ces deux valeurs est ensuite traitée et utilisée pour la commande d'une duse automatique (102), ce qui permet de purger sous contrôle les matériaux fluidiques sous pression hors de l'espace annulaire (24), entre l'élément tubulaire (18) et le trou de forage (12), créant ainsi une contre-pression dans le trou de forage.
