Product Description

NQ HQ PQ Double-tube core barrels wire-line core barrels for drilling 

Core barrels are cylindrical devices used in geology and mining to extract cylindrical rock samples (core) from the earth's surface or subterranean strata. They are typically made of durable steel or aluminum and are designed to withstand the extreme stresses and pressures of drilling operations.

Core barrels work by using a diamond-tipped or tungsten carbide bit to drill into rocks, creating a cylindrical hole. The core sample is then collected inside the barrel and retrieved using a wireline or a hydraulic system. The collected rock samples are then analyzed for their mineral content, age, and structure to better understand the geology of the area.

There are different types of core barrels, each designed to meet specific drilling requirements. The most common types include:

1. Single-tube core barrels - This type of core barrel is ideal for drilling soft rocks and sedimentary formations.

2. Double-tube core barrels - This type of core barrel is designed for drilling hard rocks and volcanic formations.

3. Triple-tube core barrels - This type of core barrel is used for drilling extremely hard rocks and deep drilling operations.

Overall, core barrels are essential tools used in geology and mining to gain a better understanding of the earth's structure and resources. They are crucial for the discovery and extraction of minerals, oil, and gas, and play a vital role in the development of various industries, including energy, construction, and manufacturing.
