摘要

An analysis and transfer system(ATS), which can subsample cores and subsequently transfer subsamples into specialized chambers before they are sent to the laboratory for further measurements, is able to keep the in-situ temperature (2～4°C) and pressure (30MPa) during the transfer process, which can prevent the changing of physicochemical properties of the cores. The system has been tested in the South China Sea twice and shows an excellent performance on pressure maintenance, the amplitude of the pressure fluctuation caused by the movement of catcher and cutting unit is less than 20%.
