FIELD: chemical treatment of bore-hole fluid. SUBSTANCE: proposed method includes continuous delivery water- soluble corrosion inhibitor into bore-hole fluid and additional treatment in permanent magnetic field of high-intensity and variable polarity; intensity of magnetic field is selected within 240-800 kA/m, alteration of polarity of 3-10 and time of treatment of 0.6-1.4 s. EFFECT: enhanced efficiency due to reduced dose of inhibitors at retained protective effect. 2 cl, 1 dwg, 3 tbl
