Abstract[English]
A carbon dioxide handling well pressure control system includes a well closure device arranged to close an annular space between a well conduit and a well construction and/or workover tool disposed in the well. The well closure device has a fluid outlet disposed below a closure element in the well closure device. A conduit connects the fluid outlet to at least one controllable orifice choke. A pump disposed in the sealed enclosure has an outlet connectable to be in fluid communication with mud solids removal devices disposed on or proximate a well construction and/or workover unit.[French]
Un système de commande de pression de puits de manipulation de dioxyde de carbone comprend un dispositif de fermeture de puits conçu pour fermer un espace annulaire entre un conduit de puits et une construction de puits et/ou un outil de reconditionnement disposé dans le puits. Le dispositif de fermeture de puits présente une sortie de fluide disposée au-dessous d'un élément de fermeture dans le dispositif de fermeture de puits. Un conduit relie la sortie de fluide à au moins un étranglement d'orifice pouvant être commandé. Une pompe disposée dans l'enceinte étanche présente une sortie pouvant être reliée pour être en communication fluidique avec des dispositifs d'élimination de solides de boue disposés sur ou à proximité d'une construction de puits et/ou d'une unité de reconditionnement.
