Zusammenfassung:	Process of pipeline and well cleaning with removal of salt and high-molecular hydrocarbon deposits includes injection of reaction thermo-chemical mix, as thermo-chemical mix one uses nitrates of sodium and ammonium in equal ratio. Before injection of thermo-chemical mix a mix of nitrate-containing reagents and surface-active substances is injected. At that as nitrogen-containing reagents one uses ammonium chloride and nitro-acid carbamide.
