A wireline coring system includes core barrel assembly and overshot assembly.The core barrel assembly is composed of inner tube group and outer tube group.Inner & outer tubes have standard length of 1.5 meters and 3 meters.
The head assembly provides: latching and pivoting spearpoint 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.
