Brief Introductions of Reaming Shells
Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional
and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can
keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also
provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This
type of diamond tool is physically longer than the standard type. So for the compensation of the
difference in reaming shell length, an appropriate inner tube extension is necessary to be used.
Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use. We can produce reaming shells with 6", 10"
and 18" length.
