Technology of Dilatant Decompaction and Permeability Enhancement of the Leached Rock Mass
Treatment of Wells in a Block Partially Taken Out of Operation
Solution injection into the 17th row had been discontinued.
Lithology: sandy and clayey–sandy formations.
According to the graphs, after treatment the total injectivity of eight wells in the 15th injection row increased from 10.45 to 34.7 m³/h (an increase of 236.4%), and the total injectivity of sixteen wells in the 17th injection row rose from 14.7 to 30.5 m³/h (an increase of 260.2%).
At the same time, the production rate of the 16th production row increased from 30 to 36 m³/h (a 20% increase), and the production rate of the 18th production row increased from 22.4 to 32.1 m³/h (a 43.3% increase).
The quality of the solutions did not change with a 32.8% increase in production rate in the 16th and 18th production rows.
