Method for increasing the flow rate of water producing wells, characterized in that weak acids are introduced into the filtration section of the well which have a dissociation constant lower than Kd = 10-3. After a long period of residence, preferably 10 to 48 hours, as well as a period of compression, hunting is carried out using a discharge pump. Then, the solution of sodium bicarbonate and / or sodium hypochlorite is introduced into the filtering section. After a long period of residence, preferably 1 to 36 hours, hunting is carried out using the discharge pump. Acetic acid, tartaric acid, cytric acid, metaboric acid and / or tetraboric acid can be used as weak acids having a dissociation constant less than Kd = 10-3. |
