HQ head assembly is the main part of HQ core barrel. HQ head assembly is used together with HQ inner tube, HQ stop ring, HQ core lifter, HQ core lifter case. They compose the HQ inner tube assembly. When using the H size wireline drilling, we do not have to remove the entire H size drill string to get the core sample from the bottom of the hole. We just need to lift the HQ inner tube assembly. It is the great advantage compare to conventional drilling.
