Prospecting Tool Wireline Core Barrel Drilling Deep Holes Double
Triple Tub
The series core barrel can be divided into BQ, NQ, HQ, and PQ
types. And this series core barrel has advantages of good drilling
property, high salvage efficiency and low consumption.
Wire-line core drilling equipment is very commonly used for mineral
exploration for deep holes because of practical usage.
Wire line core barrels are used for deep holes, mostly because they
do not need couple and uncouple the rod string each time the core
is retrieved. An overshot assembly is dropped on a cable and
directly connect to the inner tube assembly, allowing fast
retrieval of the core after each operation.
The head assembly provides: latching and pivoting spear point
mechanisms to allow insertion and retrieval of the inner tube
assembly, a bearing assembly to allow the inner tube to remain
stationary and avoid sample damage while drilling, fluid pressure
operating indications and fluid control valves.
All head assemblies incorporate a shut off valve assembly which
provides a fluid pressure signal to the drill operator when the
valve members are compressed, indicating a full or blocked inner
tube.
