A well anchor having a body with a mandrel movably extending therethrough with first and second slips connected to the mandrel. Each of the slips includes a wedge surface and the wedge surfaces engage each other whereby movement of the first and second slips toward each other will expand the slips outwardly. The wedge surfaces are at an angle to and extend across the longitudinal axis of the body for maximizing expansion.
Dispositif d'ancrage constitué d'un corps traversé par un mandrin et comportant un premier et un deuxième coins de retenue reliés à celui-ci. Chaque coin de retenue comporte une surface oblique; les surfaces obliques de l'un et l'autre coins de retenue venant en contact, leur mouvement d'avance a pour effet de chasser les coins de retenue vers l'extérieur. Les surfaces obliques décrivent un angle par rapport à l'axe longitudinal du corps et traversent celui-ci, ce qui maximise l'expansion du dispositif.
