Title (EN) PROPORTIONAL CONTROL OF RIG DRILLING MUD FLOW
(FR) COMMANDE PROPORTIONNELLE D'ÉCOULEMENT DE BOUE DE FORAGE D'UN APPAREIL DE FORAGE
Abstract:
(EN) A system includes a mud pump for pumping a drilling mud from a drilling mud source, through a drill string, out a drill bit and into an annular, and a plurality of chokes disposed down stream from the mud pump, including a first choke disposed between the mud pump and the drill string, and a second choke disposed between the mud pump and a mud tank. The system further includes a fluid discharge conduit in fluid communication with the annular space for transferring the drilling mud to handling equipment in fluid communication with the mud tank. The first choke receives the drilling mud from the mud pump at a first flow rate, the first choke reduces drilling mud flow rate to a second flow rate less than the first flow rate, and the second choke reduces drilling mud flow rate to a third flow rate.
(FR) Système comprenant une pompe à boue pour pomper une boue de forage d'une source de boue de forage, la faisant passer par un train de tiges de forage, hors d'un trépan et dans un espace annulaire, et une pluralité de duses disposée en aval de la pompe à boue, comprenant une première duse disposée entre la pompe à boue et le train de tiges de forage, et une seconde duse disposée entre la pompe à boue et une cuve à boue. Le système comprend en outre un conduit de décharge de fluide en communication fluidique avec l'espace annulaire pour transférer la boue de forage à l'équipement de manipulation en communication fluidique avec la cuve à boue. La première duse reçoit la boue de forage provenant de la pompe à boue à un premier débit, la première duse réduit le débit d'écoulement de la boue de forage à un deuxième débit inférieur au premier débit, et la deuxième duse réduit le débit d'écoulement de la boue de forage en l'amenant à un troisième débit d'écoulement.
