NQ locking coupling, adaptor coupling
These products are Inlay alloy & with chrome plated, which will improve the longer working life of the core barrels.
Wireline double tube core barrels are primarily used in deep coring. With an overshot device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved.
Wireline triple tube core barrels are generally required in broken, fractured formations. They incorporate a third, split inner tube on base of wireline double tube core barrel. This can be pumped out of the inner tube after retrieval, allowing the core to be examined in its in-situ state.
