It has high drilling efficiency, high bit coring rate, long working life, low labor intensity. With the more deep drilling depth, its advantage is more obvious.The locking coupling of our PQ core barrels are with alloy inserts, which will make the working life of core barrel more longer and better stability.These core barrels are available in industry standard hole sizes A, B, N, H and P. All parts are fully interchangeable with most other manufacturers' wireline core barrels. Special requirements can also be met on request.
