Features:
1. Available in all standard drilling sizes
2. Hardened alloy as raw material,it can serve in a long lifespan
3. Core lifters are divided into slotted and flutted .They
have the advantages of good springness and long life.
4. Our company produces all kinds of core lifters ,which have the
merits of good springness and long life. The core lifter pedestal
experiences salt bath quenching which makes it good stability.
The drilling fluid circuit operates withinthe available annular
areaprovided.More specifically, after travelling through the drill
rods, the fluid enters the core barrel.
There it is channelled between the inner and outer tubes, exiting
via the throat of the diamond bit, and back out between the outer
tube and bore hole wall to the collar .
At the bit end of the inner tube, core lifter case adjustment and
core lifter selection are of great importance. The core lifter case
needs to be placed close enough to the throat of the bit to allow
for efficient core breakage, butundesirable increase in fluid
pressureand/or sample washing from the drilling fluid.
By design, the tapered core lifter slides along the inside of the
core lifter case, wedging and securing itself onto the core during
core recovery and breaking.
