MODEL: Core Barrels
THigh roughness cover of tungsten carbide throughout inside diame- ter provides reliable core catching during brake-off and pulling-out
Product Nomenclature:
SK - 178 / 100
Core barrel - Body outside diameter, mm / Core diameter, mm
Featurs:
- Increased body diameter and reinforced threads increase service life and provide continuous trouble-free operation of core barrel;
- Core tube tapered thread considerably speeds up make up and lay down operations;
- Inner core tube suspension design allows making fast clearance adjustment between core head and inner-tube shoe and, if necessary, change standard heavy series thrust bearing within 10-15 minutes at rig site;
- Collet core-cutters ahave necessary elastic characteristics due to special heat treatment technology and equipped with high roughness cover of tungsten carbide throughout inside diameter, which provide reliable core catching during brake-off and pulling-out operations;
- The variety of toggle-type core catchers allows selecting overlapped core tube cross-section area depending on type of formation for reliable core keeping during pulling out operation;
- Spiral centralizers decrease vibrations and fluctuations and allow increasing of core recovery percentage in fissured, cavernous and broken formations.
