A system for accessing a subterranean zone (24) from an entry well (12) including an entry well (12) extending from the surface (22). The entry well (12) has a substantially vertical portion. One or more drainage wells (14) extend from the entry well (12) to a subterranean zone (24). One or more articulated wells (16) extend from the entry well (12) to the subterranean zone (24). At least one of the articulated wells (16) intersects at least one of the one or more drainage wells (14) at a junction proximate the subterranean zone (24). A drainage pattern (32) is formed coupled to the junction and operable to conduct fluids from the subterranean zone (24) to the junction.
L'invention concerne un système pour accéder à une zone souterraine (24) à partir d'un puits d'entrée (12) qui s'étend à partir de la surface (22) et a une partie sensiblement verticale. Un ou plusieurs puits de drainage (14) s'étendent du puits d'entrée (12) à une zone souterraine (24). Un ou plusieurs puits articulés (16) s'étendent du puits d'entrée (12) à la zone souterraine (24). Au moins un des puits articulés (16) coupe au moins un des puits de drainage (14) en un point de jonction proche de la zone souterraine (24). Une configuration de drainage (32) est formée en accouplement au point de jonction et sert au transport de fluides de la zone souterraine (24) au point de jonction.
