[origin: EP0250016A2] A tool for cementing a casing or other well pipe in a well comprises a substantially tubular collar and a plurality of port openings passing through the wall of said collar, which openings are oriented at such an inclined position relative to the collar that during injection of a cement slurry from the interior of the collar into an annular space surrounding the collar the flow of cement slurry obtains a swirling motion through said annular space.
