Everything for Oilwell Cementing

Everything

but the Cement!
MULTIPLE STAGE
CEMENTING COLLAR
This tool is used to effectively cement upper
sections of the casing string after displacing
cement around the lower section. The tool provides a means of opening and closing port
holes for cement displacement and positive
containment of the cement after displacement.
All internal parts are easily drilled, and are
firmly held from rotating during drilling. The
port closing sleeve is positively locked in
position after cementing.
When running the collar, it is advisable to place
a casing centralizer above and below and to
run a cementing basket below the cementing
ports. After running the collar to setting depth,
the lower section is cemented in the conventional
manner except the cement is displaced with
the flexible cementing plug furnished with the
collar. This is bumped against the shut-off
baffle which is also furnished. A slight pressure
build-up of 300-400 psi will assure plug is
seated in baffle. The port holes in the multiple
stage cementing collar are opened for doing
the second stage by dropping the trip bomb
and applying approximately 800-1000 psi pressure. The second stage is displaced with the
closing plug which is also furnished with the
tool. When the closing plug bumps approximately
800-1000 psi pressure will close the port holes.
