FIDELITY CORING DEVICE

WIPO Patent Application WO/2020/113719

A1

Disclosed is a fidelity coring device, comprising an outer barrel (10) and a fidelity cabin (30), wherein the fidelity cabin (30) is arranged in a hollow cavity of the outer barrel (10), the outer barrel (10) is used for drilling a rock core, the fidelity cabin (30) is used for containing the rock core, and a heater (12) and a third liquid reservoir (60) are arranged in the outer barrel (10). By comparing the temperature of the rock core in the detected fidelity cabin (30) with the temperature at a coring position, the heater (12) heats the fidelity cabin (30) or a coolant stored in the third liquid reservoir (60) cools the fidelity cabin (30) to enable the temperature in the fidelity cabin (30) to be identical to the temperature at the coring position. By comparing the temperature in the detected fidelity cabin with the temperature at an original coring position, the heater conducts heating or the coolant conducts cooling, thus enabling the temperature in the fidelity cabin to be identical to the temperature at the coring position and realizing a heat preservation effect.
