| titleOfInvention | A well cleaning method for in-situ leaching and mining of uranium |
| abstract | The invention provides a well cleaning method for in-situ leaching and mining of uranium, belonging to the technical field of in-situ leaching and mining of uranium. In the present invention, a packer is inserted into the production well of a uranium deposit to the upper surface of the filter; water is injected into the packer to pressurize, so as to realize the setting of the packer; chemical washing is injected into the ore bed through the packer. Well agent, the chemical well cleaning agent has a mud skin dissolution reaction with the mineral layer; after the mud skin dissolution reaction, the packer is unsealed, the packer is lifted to the surface, and then the uranium The production well of the deposit is pumped, and when the pH value of the obtained well-washing water is 6.5-7.5, the well-washing is completed. The invention seals the ore bed through a packer, and then injects the chemical well cleaning agent into the ore bed directionally under the action of pressure, reduces the dilution of the chemical well cleaning agent by the solution in the well, fully dissolves the sediment by using the chemical well cleaning agent, and restores the penetration of the ore bed. It can improve the pumping volume of production wells, and then improve the cleaning effect. |
