Core Barrels
Preview
“BURINTEKH”, Ltd core bits allow for high-quality coring in rocks of all categories of core sampling difficulty.
Benefits and Features:
- Well diameter from 93 mm to 311.2 mm.
- Increased core recovery length per run - up to 270 meters (with standard core recovery).
- Increased core diameter - 45; 52; 67; 80; 100; 101.6; 110; 133 mm - provides an increase in the core information value and its quality.
- Possibility of equipping barrels with additional units - increasing the core recovery and its information value, reducing the number of jams.
- Own design - ease of assembly and core extraction.
- A wide range of core bits of own production (PDC/impregnated/combined/TSP)
Core barrels “VOSTOK”
Barrels “VOSTOK” designed for heavy drilling conditions, strong vibrations, complex rock cross-sections, high temperatures and pressures. Core barrels “VOSTOK” have reinforced tool joints, highly resourceful hanger and reinforced core catchers. Core barrel can be equipped with additional sections.
Core barrels “SIBERIA”
Core barrels CBS 6 ¾ x 4 (Core barrel Siberia) and CBS 4 ¾ x 2 5/8 were designed in accordance with the international requirements for core barrels. Reliable systems for coring with a long life. Allow coring in various rocks.
The line of core barrels “Siberia” worthy competes with the best world analogues.
