Frequently Asked Questions

What is the working principle of diamond core bits?

Diamond core bits use synthetic or natural diamonds embedded in the matrix to grind through rock. The rotating bit cuts a cylindrical core, which is preserved inside the barrel for geological analysis.

What are wireline core barrels used for?

Wireline core barrels allow retrieval of core samples without removing the entire drill string. A wireline cable pulls the inner tube assembly to the surface, saving time and increasing efficiency.

How are core barrels classified?

Core barrels are classified by diameter (e.g., NQ, HQ, PQ), recovery method (single, double, triple tube), and operation type (wireline or non-wireline).

What materials are used in drill pipe manufacturing?

We use high-strength alloy steels including 4130, 4140, 4145, and 4150. Tool joints are friction-welded for durability and leak resistance.
