core barrel overview history boart longyear introduced the wireline core retrieval system in 1958 being the first diamond drilling exploration product manufacturer to offer this revolutionary system which increased productivity on the worksite and made tripping core from the bottom of the hole safer for the drilling assistant prior to the introduction of wireline technology the drill crew was required to pull the entire rod string out of the ground to gain access to the conventional core barrel located behind the drill bit once the core barrel was emptied the complete rod string would be lowered into the exploration hole prior to drilling the next core run the introduction of wireline technology allowed for the retrieval of the full inner-tube without the need to pull the rod string out of the hole this was accomplished by creating a completely independent inner-tube which is not attached to the rod string but rests at the bottom of the rod string directly behind the drill bit mounted at the top of the inner-tube assembly is a device called a head assembly the head assembly includes the latching and retrieval hardware required to bring the inner-tube to the surface when the inner-tube is full a device called an overshot is lowered down the hole via a wireline cable and brought to the surface by use of a winch once the inner-tube assembly is at the surface an empty innertube is lowered into the hole so drilling can resume core retrieval system 10 copyright © 2009 boart longyear all rights reserved 1950 1960 1970 1980 1958 boart longyear introduced the original wireline core retrieval system 1966 launched improved patented q® wireline system 1989 introduced thin kerf qtk to the q® wireline system tm[close]

core retrieval system the boart longyear design engineering team continued to refine the initial system resulting in the launch of the industry-standard patented q® wireline system in 1966 with the goal of providing our customers a larger diameter core sample without increasing hole diameter boart longyear introduced the thin kerf wireline system product line in 1989 in 1998 boart longyear once again secured its position as the leading innovator in wireline technology by introducing the patented link latch mechanism while the q® system was adapted to pump-in applications for inclined holes underground boart longyear maximized reliability of the latching mechanism with the release of the patented quick pump-in head assemblies in 2002 this head assembly added positive latch indication and removed the pump-in lip seal from the latch retracting case eliminating latching concerns against in-ground fluid gas pressure zones and fluid evacuation or suction boart longyear launched the patent pending quick descenttm core barrel head assembly providing the customer with the potential to increase core barrel descent speed up to 30 this quick descent head assembly is a central component of the high productivity coring systemtm which also includes the stage3 diamond coring bit and the v-walltm coring rod 1990 2000 2010 1998 introduced nextqtm wireline system 2002 added quick pump-in head assembly to q® wireline system 2008 released patented quick descent core barrel assembly 11 copyright © 2009 boart longyear all rights reserved.[close]
