The present invention discloses a combustible ice coring device and method, wherein a combustible ice coring device comprises: a coring device including a coring bin for storing combustible ice; a temperature sensor, the The temperature sensor is arranged above the coring bin; the heat conducting coil includes an input port and an output port, and the heat conducting coil is arranged on the outer side wall of the core bin; the cold material conveying pipe, the The cold material conveying pipe includes an input pipe and an output pipe, the input pipe is communicated with the input port; the output pipe is communicated with the output port; a flow control valve, the flow control valve communicates with the cold material conveyance A tube is connected and in communication with the temperature sensor. During the coring process, the temperature in the coring bin is kept at the in-situ temperature by monitoring and timely feeding the cold material for heat exchange, thereby avoiding the in-situ temperature loss. |
