发明名称 METHOD FOR RESTRICTION OF STRATAL WATER INFLOW TO THE WELL
摘要 Method for restriction of inflow of stratal water to the well includes sequential pressing to the bed, in same portions, at least two times, of calcium chloride solution with concentration from 5 % to 15 % and solution with hydrogen index larger than six, this is formed after mixing sodium or potassium hydroxide, nitrile-trimethyl- phosphonic acid and water at following component ratio, mass % : 3-10 of sodium or potassium hydroxide, 2-8 of nitrile-trimethyl- phosphonic acid, water - the rest. Effectiveness of work on restriction of inflow of stratal water is increased due to formation of conditions for better mixing in strata of solutions going to reaction with each other with formation of enough amount of gel-like deposit there.
