Core lifter

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.

Overshot is a necessary device in wireline drilling. It is dropped on a cable and directly couples onto and lifts up the inner tube assembly, eliminating the need to couple and uncouple the rod string each time the core is retrieved.

NQ/BQ/HQ overshot assembl are all available.
