Well tool packing element systems that do not require a back-up element or component include a mandrel (30), an upper supporting member (26), a lower supporting member (28), a cantilever element (22), and a ramp element (24) disposed on the mandrel. The cantilever element and ramp element are disposed on the mandrel with an interface angle between the cantilever element and the ramp element, the interface angle being less than 90 degrees, preferably in a range from 40 degrees to 60 degrees, and more preferably at an angle greater than 45 degrees. When an axial load is applied to upper and lower supporting members, cantilever element and ramp element are forced outward and into an inner wall surface of a casing to seal off the casing bore.

L'invention concerne des systèmes d'élément de garnissage d'outil de puits qui ne nécessitent pas d'élément ou de composant de blocage, comprenant un mandrin (30), un élément de support supérieur (26), un élément de support inférieur (28), un élément en porte-à-faux (22), et une rampe (24) placés sur le mandrin. Cet élément en porte-à-faux et cette rampe sont placés sur le mandrin avec un angle d'interface entre l'élément en porte-à-faux et la rampe, cet angle d'interface étant <90°, de préférence compris entre 40° et 600, et mieux encore, à un angle supérieur à 45°. Lorsqu'une charge axiale est appliquée sur les éléments de support supérieur et inférieur, l'élément en porte-à-faux et la rampe sont pressés vers l'extérieur dans une surface de paroi intérieures d'un tubage afin de colmater le trou de tubage.
