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