Abstract
A device and a method for transferring and storing a deep in-situ core in a sealed and pressure-maintaining manner includes a pressure vessel, a sealed storage vessel, a control system, a pressure regulation system and at least one spherical valve. The pressure vessel includes a first barrel and a first end sealing piston mounted at a first end of the first barrel and being slidable in the pressure vessel. The sealed storage vessel includes a second barrel and a second end sealing piston which is mounted at a first end of the second barrel. At least one spherical valve is connected between the first barrel and the second barrel. The pressure regulation system is configured for regulating an amount of water in the second barrel. The control system includes a first pressure sensor, a second pressure sensor, and a controller.
