Bq/Nq/Hq/Pq Wireline Core Barrel Assembly for Exploration Core Drilling
Product Description
Best Drilling manufacture and supply wireline core barrels for geologival drilling.
The Wireline Core Barrel is an essential tool in geological exploration, widely used in mining, civil engineering, and environmental studies. Designed for efficient core sampling, this advanced drilling equipment is ideal for retrieving undisturbed core samples from various rock formations, enabling precise analysis and decision-making in the field.
Key Components of a Core Barrel Assembly
Core Barrel: The core barrel is the central component of the assembly. It consists of a cylindrical tube that houses the core samples. The core barrel is designed to capture and retain the rock core without causing significant disturbance to the sample.
Drill Bit: Attached to the core barrel, the drill bit is responsible for cutting into the rock and facilitating the extraction of the core sample. Drill bits come in various designs, including diamond bits, which are ideal for cutting through hard and abrasive materials.
Core Lifter: Core lifters are internal components of the core barrel that help hold the core in place during extraction. They ensure that the core remains intact and is not damaged or fragmented during the drilling process
Inner Tube: The inner tube is a removable section of the core barrel that contains the core sample once it has been extracted. The inner tube is often lined with a material that preserves the core's integrity and prevents contamination.
Reaming Shell: The reaming shell is used to stabilize the core barrel and maintain its alignment with the drill hole. It helps in preventing deviations and ensures that the core is extracted accurately.
Core Catcher: The core catcher is a crucial component that captures and holds the core sample as it is extracted from the borehole. It prevents the core from falling back into the hole and ensures that the sample is collected for analysis.
Drill Rods: Drill rods are long, slender tubes that connect the core barrel to the drilling rig. They transmit rotational and axial forces to the core barrel and facilitate its movement during drilling.
