PROCESS FOR CLEANING PIPELINES AND WELLS WITH REMOVAL OF SALT AND HIGH-MOLECULAR HYDROCARBON DEPOSITS

摘要

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.
