Drilling the Cretaceous Songliao Basin in China

New record in deep drilling

Engineers of Songliao Basin Drilling Project (SK-II) developed a new drilling tool  with 311 mm diameter to drill from 2865m to 4500m to retrieve cores of 214 mm diameter without reaming. This tool has been used since April and runs well with an 8.2 m footage per round trip. This is the first time that a 311 mm diameter drilling tool is used for continuous coring in the history of deep drilling.

By August 2015, SK-II has drilled 3350.15 m, including 486.92 m of 311 mm drilling with 480.30 m core (recovery =98.64%). Now persistent efforts are made to use double core barrel drilling tools which would extend the footage per round trip to more than twice than before.

The DPCSB project (SK-II) proposes to obtain about 4500 m cores of Huoshiling to Quantou Formation, to be combined with the existing SK-I(n) and SK-I(s) to form the first nearly complete Cretaceous terrestrial sedimentary record in the world. This will provide excellent high resolution climate records of the terrestrial environment for the whole Cretaceous.

In 2006 and 2007, two scientific boreholes, SK-I(n) and SK-I(s), supported by Ministry of Science and Technology of China (MOST) and Daqing Oilfield, were completed in the basin with total length of 2485.89 m and recovery ratio of 96.46%, covering the complete Mid to Upper Cretaceous strata.
