Introduction
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.
The core barrel assembly is composed of the inner-tube group and outer-tube group.The inner-tube group is composed of:Head Assembly,Inner Tube,Core Lifter Case,Core Lifter,Stop Ring.
The inner-tube group collects the core sample during the drilling process and is independent of the outer-tube group.The outer-tube group is composed of the remainder of the core barrel components: Locking Coupling,Adapter Coupling,Outer Tube.
The outer-tube group always remains at the bottom of the hole and houses the inner-tube group during the drilling process.
