Abstract

The invention relates to a cementing head for oil wells or the like, comprising a body adaptable by a connecting means on the upper end of a casing placed inside the well, and means for connecting the head with a supply station supplying at least one fluid under pressure, this cementing head comprising a tubular magazine or container, open at its lower end, extending downwardly from the body in order to be placed at least partly inside the casing with which it creates an annular space, at least one plug mounted in the container with radial elastic deformation prestressing and capable of sealingly occupying the casing after expelling of the container, and an expelling jack for expelling the plug from the container.
