Title:
ROCK CORE FIDELITY CABIN HAVING THERMOSTATIC FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/034359
Kind Code:
A1
Abstract:
A rock core fidelity cabin having a thermostatic function, comprising a mechanical part and an electric appliance part. The mechanical part comprises an inner coring barrel (8) and an outer coring barrel (6); the outer coring barrel (6) is sleeved on the inner coring barrel (8); the upper end of the inner coring barrel (8) is connected to one end of a pipeline, and the other end of the pipeline is connected to a liquid nitrogen storage tank (25); the liquid nitrogen storage tank (25) is located inside the outer coring barrel (6); the outer coring barrel (6) is provided with a flap valve (3); the electric appliance part comprises an electric heater (29), a temperature sensor (5), and an electrically controlled valve (26) provided in the pipeline; the temperature sensor (5) is connected to a processing unit (24); the electric heater (29) and the electrically controlled valve (26) are both controlled by the processing unit (24); the electric heater (29) is used for heating the interior of the outer coring barrel (6); the temperature sensor (5) is used for detecting the temperature in the fidelity cabin. The rock core fidelity cabin can automatically control the temperature in the fidelity cabin, and facilitates maintaining the state of a rock core in an in-situ environment.
