Title: Cementing of boreholes
Inventor: HOGARTH PETER JOHN MICHAEL
IPC: E21B33/16
Filed: 1987-08-14
Abstract: In a two-stage operation to cement the annulus between the wall of a borehole and a casing string (10), a stage collar (14) is inserted as a section within the casing string to enable cement to be pumped out through ports (18, 16) in the stage collar. The stage collar (14) includes a slidable sleeve (17) provided with an internal seat (19) which is engageable by lugs (54) of a pressure pack-off tool assembly (28). The tool assembly (28) is movable within the casing string to control both the opening and the closing of the stage collar. After the second stage cementing operation through the stage collar (14), an overpull is exerted on the drill string which, via the tool assembly (28), first closes and locks closed the stage collar and then breaks off the seat (19) which is lifted to the surface with the drill string. This leaves the borehole clear for the next drill bit without the need to drill out a collar, without any danger of leakage through the locked-shut stage collar (14). <IMAGE>
