| titleOfInvention | A heat extraction device and heat extraction method suitable for hot dry rock formation |
| abstract | The invention discloses a heat extraction device and a heat extraction method suitable for dry-hot rock formations, and relates to the technical field of dry-hot rock resource exploitation. The compressed gas supply component, the cold water supply component and the separation processing component, the production wellhead device is arranged at the top of the production well, the double-wall drill pipe includes the drill pipe inner pipe and the drill pipe outer pipe, the insulation pipe is connected with the drill pipe inner pipe, and the drill pipe outer pipe is The lower end of the pipe is connected with the gas-liquid mixing chamber, the side wall of the lower end of the inner pipe of the drill pipe is provided with a plurality of through holes, the through holes correspond to the positions of the gas-liquid mixing chamber, the compressed gas supply part is connected with the outer pipe of the drill pipe, and the cold water supply part It is connected with the production wellhead device, and the two ends of the separation processing component are respectively connected with the inner pipe of the drill pipe and the cold water supply component, and the separation processing component is used for gas-liquid separation and heat absorption. The heat extraction device and the heat extraction method reduce the development cost, avoid the earthquake risk induced by large-scale fracturing, and improve the recovery rate. |
