It is noted mechanical impurities occurred in the samples of hydrogen sulfate-containing fluid “Tatarstan” in the form of silica sand or clay inclusions reduce the performance of the corrosion inhibitor. The residual concentration of the corrosion inhibitor was established by NMR-spectroscopy. The critical density of the mechanical impurities drastically reducing the efficiency of the corrosion inhibitor was specified.e efficiency of the corrosion inhibitor was specified.
