摘要

FIELD: metallurgy.;SUBSTANCE: invention can be implemented in oil industry for protection of oil field equipment and for acid treatment of boreholes, also for treatment of bottomhole zone of oil and pressure wells. The inhibitor contains, wt %: urotropin or polyethylene-polyamine 5-80, copper salt 0.1-10 and hydrochloric acid or mixture of 12 % hydrochloric and 5 % acetic acid (at their ratio 3-(6:1) correspondingly) - the rest. The method of production of inhibited haloid-hydrogen acid consists in dilution of haloid-hydrogen acid with water and in adding a described above inhibitor into it.;EFFECT: increased efficiency of inhibiting.;3 cl, 2 tbl
