| titleOfInvention | A double-J-type double-level horizontal production and irrigation well group and heat production method |
| abstract | The invention discloses a double-J type double-level horizontal mining and irrigation well group and a heat recovery method, which belong to the technical field of heat energy collection. The production and injection well group includes: J-type reinjection well and J-type production well; J-type reinjection well includes the first straight well section, the first inclined well section and the first horizontal section connected sequentially from top to bottom; the J-type production well The well includes a second vertical well section, a second inclined well section and a second horizontal section connected in sequence from top to bottom; casings are set in the first straight well section and the second vertical well section; the first horizontal section and the second horizontal section The section is connected; the wellhead of the J-type reinjection well and the J-type production well is connected with a heat exchange system. In the present invention, the double-J-type double-level horizontal production and irrigation well group is composed of J-type reinjection wells and J-type production wells with the same structure, which can greatly increase the heat transfer area, thereby changing the heat transfer area of conventional geothermal recovery technology The shortcomings of small size and low efficiency can improve the heat exchange efficiency and the economic benefits of mining. |
