In accordance with the present invention, a plurality of methods and devices are provided for solving important and serious problems posed by lateral (18) (and especially multilateral) completion in a wellbore (10) including methods and devices for sealing the junction between a vertical (10) aad lateral (23) well. Methods are disclosed wherein deformable devices (35) are utilized to selectively seal the juncture between the vertical (10) and lateral (23) wells. Such deformable devices (35) may comprise (1) an inflatable mold which utilizes a hardenable 1qiuid (e.g., epoxy or cementious material slurry) to form the seal; (2) expandable memory metal devices; and (3) swaging devices for plastically deforming a sealing material.
Une pluralité de procédés et de dispositifs permet de résoudre les problèmes importants et sérieux que pose le tubage latéral (18) (et particulièrement multilatéral) dans un puits de forage (10), et comprend des procédés et des dispositifs permettant de colmater la jonction entre un puits vertical (10) et un puits latéral (23). La présente invention décrit des procédés selon lesquels des dispositifs déformables (35) sont utilisés pour colmater sélectivement la jonction entre les puits vertical (10) et latéral (23). Lesdits dispositifs déformables (35) peuvent comprendre (1) un moule gonflable qui utilise un liquide durcissable (par exemple de l'époxy ou une boue à base de ciment) pour former le colmatage; (2) des dispositifs métalliques à mémoire dilatables; et (3) des dispositifs de refoulement destinés à déformer plastiquement un matériau de colmatage.
