Reaming Shell
1. Introduction
The reaming shell is set with natural or synthetic diamond, and it
is used to couple the drill bit with the core barrel. Its main
function is to ream the hole to the correct constant specific
diameter which ensures adequate clearance for the core barrel and
sufficient clearance for the new bit which replaces an old one. It
also acts as a stabilizer for drill bit. We can produce reaming
shells with 6", 10" and 18" length. Reaming shells (with double
pads or three pads) are suitable to use in all formation conditions
ranging from broken and abrasive to consolidated and non-abrasive.
As this kind of reaming shell is physically longer than the
standard type, it is necessary to use an appropriate inner tube
extension in order to compensate for the difference in overall
reaming shell length.
