Background
The salt mine drilling solution mining technology is a technology commonly used in salt mine mining, and is characterized in that a well is drilled on the ground to reach a rock salt ore body, a central pipe is sleeved in a pipe sleeve and goes down to the rock salt ore body, water is injected to dissolve rock salt to form a rock salt solution cavity, and brine in the rock salt solution cavity returns to the ground. When a well drilling water-soluble exploitation technology is used, in order to reduce the production cost, the brine transportation cost and the salt production cost as much as possible, the concentration of the exploited brine is better to be saturated, so that the central pipe and the sleeve are deeper to the greatest extent during normal exploitation, and particularly, the production department determines that the pipe descending depth is deeper after the brine well is repaired.
Therefore, during production, brine rises to the ground from the rock salt dissolving cavity, is influenced by the ground temperature gradient, and is gradually reduced in temperature or tends to be saturated underground, so that the solubility is reduced, and the supersaturation phenomenon can occur, and salt solute is separated out and crystallized. When the tank does not have enough power to flush the crystals out of the ground, the precipitated salt crystallization solute can be attached to the inner wall of the pipeline, and finally the salt crystallization blocks the pipeline. Particularly, salt crystals are seriously blocked in the production of certain brine wells with overhigh brine-producing concentration, which not only influences the brine-producing capability, but also seriously threatens the safety of the brine wells.
