Abstract

Et brønnintervensjonssystem (10) som er tilpasset for å koples til en undervanns brønnhodesammenstilling (12) beskrives. Undervannsbrønnhodesammenstillingen har et brønnhode, et havbunnstre (14) koplet til brønnhodet og en brønnkontrollpakke, som har en flerhet brønnkontrollventiler, koplet til havbunnstreet. Intervensjonssystemet (10) omfatter en beholder (44) for lagring og utsetting av kabelverktøy, første fluidkommunikasjonsmiddel som forløper mellom beholderen og en spylefluidkilde (57) og et andre fluidkommunikasjonsmiddel som forløper mellom beholderen og brønnkontrollpakken på et sted ovenfor i det minste én brønnkontrollventil. I bruk fortrenger spylefluid som tilføres beholderen via det første fluidkommunikasjonsmiddel fluid fra beholderen inn i det andre fluidkommunikasjonsmiddel og inn i brønnkontroll pakken. Utførelser av oppfinnelsen beskrives.A well intervention system (10) adapted to be coupled to an underwater wellhead assembly (12) is described. The subsea wellhead assembly has a wellhead, a subsea tree (14) connected to the wellhead, and a well control package, which has a plurality of well control valves, connected to the subsea tree. The intervention system (10) comprises a container (44) for storing and deploying cable tools, first fluid communication means extending between the container and a flush fluid source (57), and a second fluid communication means extending between the container and the well control package at a location above at least one well control valve. In use, flushing fluid supplied to the container via the first fluid communication means displaces fluid from the container into the second fluid communication agent and into the well control package. Embodiments of the invention are described.
