Abstract | An well assembly having a housing with an inner surface, the assembly including a tubular member inserted in the housing and having an outer surface. The assembly further includes a plurality of protrusions extending from one of the inner or outer surfaces, the protrusions separated by gaps defined between adjacent protrusions. In addition, the well assembly includes a metal to metal seal pressed against and deformed by the protrusions. A plurality of hollow tubes are provided for insertion in the gaps between the protrusions, the tubes being collapsible upon engagement with the metal to metal seal.
Ensemble puits possédant un logement doté d'une surface intérieure, l'ensemble comprenant un élément tubulaire introduit dans le logement et possédant une surface extérieure. L'ensemble comprend en outre une pluralité de saillies s'étendant depuis l'une des surfaces intérieure ou extérieure, les saillies étant séparées par des espaces délimités entre des saillies adjacentes. De plus, l'ensemble puits comprend un joint métal-métal pressé contre les saillies et déformé par celles-ci. Une pluralité de tubes creux sont prévus pour introduction dans les espaces entre les saillies, les tubes pouvant s'affaisser lors de l'entrée en prise avec le joint métal-métal. |
