Title (EN) IN SITU EXPANDABLE TUBULARS
(FR) ÉLÉMENTS TUBULAIRES DILATABLES IN SITU
Abstract: front page image
(EN) Expandable tube members that are fabricated from a composite material that includes a structural plastic, which structural plastic includes phase change materials that undergo a permanent expansion upon exposure to wellbore conditions. This permanent expansion of the structural plastic causes the expandable tube member to expand radially and/or longitudinally without the use of an expansion tool. The expandable tube member can be used to control fluid loss, patch wells, stabilize a formation in a wellbore, enhance flow, provide sand screening, and repair damaged pipes, casings, or liners.
(FR) L'invention concerne des éléments tubulaires dilatables fabriqués en matériau composite comprenant un plastique structural, lequel plastique structural comprend des matériaux à changement de phase qui subissent une dilatation permanente lorsqu'ils sont exposés à des conditions de puits de forage. Ladite dilatation permanente du plastique structural amène l'élément tubulaire dilatable à se dilater radialement et/ou longitudinalement sans l'utilisation d'un outil de dilatation. L'élément tubulaire dilatable peut être utilisé pour réguler une perte de fluide, réparer des puits, stabiliser une formation dans un puits de forage, améliorer l'écoulement, assurer un filtrage contre le sable, et réparer des conduits, des gaines, ou des chemises endommagés.
