Abstract
A core sampling and preservation system comprises the following sequentially connected modules: a drive module (), a preservation module () and a core sampling module (). The core sampling module () comprises a core drilling tool and a core sample storage compartment. The preservation module () comprises a core sample preservation container. The drive module comprises a core drill having a liquid channel. The core sample preservation container comprises an inner core barrel (), an outer core barrel () and an energy storage device (). The outer core barrel () is sleeved onto the inner core barrel (). An upper end of the inner core barrel () is in communication with a liquid nitrogen storage tank (). The liquid nitrogen storage tank () is positioned inside the outer core barrel (). The energy storage device () is in communication with the outer core barrel (). The outer core barrel () is provided with a butterfly valve (). The system facilitates preserving a core at in-situ conditions, and has an increased drilling speed, thereby enhancing core sampling efficiency.
