| titleOfInvention | Method for treating of down-hole zone of bed |
| abstract | FIELD: oil production industry. SUBSTANCE: this can be used for restoring and increasing productivity of oil wells having their down-hole zone clogged with asphaltic-resin-paraffin depositions. According to method, down-hole zone of bed is treated by injection of solvent into it which is selected from group of: chlor- and/or fluohydrocarbons of methane, ethane, pentane line. Then, solution is kept in well zone for technological delay. Additional acid treatment is undertaken by solution of sulfaminol in brine water of following concentration, mass %: sulfaminol 14-18, brine water - the balance before injection of solution; and of concentration, mass%: sulfaminol 7-9, brine water - the balance after injection of solution. This procedure gives stable increase in productivity of low-output wells by 10-12 times and maintains it during long period of 2-3 years and more. EFFECT: high efficiency. 1 tbl |
