    • Home page
    Classification of Specific-Purpose Core Barrel

    Classification of Specific-Purpose Core Barrel

    Specific-purpose core barrel are customized products, and the total solution is applied to drilling construction under special geological conditions.Products: Full-Hole Core Barrel, Asymmetric Core Barrel,Large-diameter Core Barrel for oil and gas wells.Full-Hole Core Barrel Features: Flat structure and spiral structure.Main function: Reduce the clearance between core barrel and hole wall, reduce the judder of core barrel, and prevent the drilling hole from skewing.Caliber Specification:N,H, P   Asymmetric Core Barrel Characteristics: The geometric center of core barrel is not in the same axis as the center of rotation. Main function: Used at the bottom of the drill rod column to correct the drilling trajectory.Caliber Specification:N, H,P   Large-diameter core barrel for oil and gas wells Features: Selection of core barrel is based on the internal diameter of the drill rod.Main function: Matching with API standard oil drill rod, adapting to oil and gas wells wireline core drilling.Caliber specifications: ST216/49,ST216/63
