Summary:Provided is an inner sleeve, a downhole tool, and a method for cementing. The inner sleeve, in at least one aspect, includes a tubular having an inside tubular surface and an outside tubular surface. The inner sleeve, according to this aspect, further includes a collet including two or more collet fingers coupled to one end of the tubular, the collet having an inside collet surface and an outside collet surface, and further wherein the inside collet surface flares outward from the inside tubular surface by an angle (?0) when the collet is in its natural state. La présente invention concerne un manchon interne, un outil de fond et un procédé de cimentation. Le manchon interne, dans au moins un aspect, comprend un élément tubulaire ayant une surface tubulaire intérieure et une surface tubulaire extérieure. Le manchon interne, selon cet aspect, comprend en outre une douille de serrage comprenant deux doigts de douille de serrage ou plus couplés à une extrémité de l'élément tubulaire, la douille de serrage ayant une surface de douille de serrage intérieure et une surface de douille de serrage extérieure, et la surface de douille de serrage intérieure s'évasant vers l'extérieur à partir de la surface tubulaire intérieure selon un angle (?0) lorsque la douille de serrage est dans son état naturel.
