In the field development practice, the most common method for protecting oilfield equipment and pipeline surfaces from inorganic salt deposits is inhibitor protection. To enhance prevention efficiency, a salt deposit inhibitor has been developed, which contains a surfactant, acid, and anionic polymer. The aim of this development is to eliminate the need for scarce and expensive reagents, increase formation productivity by preventing the formation of inorganic deposits during the treatment of carbonate and terrigenous productive formations, and eliminate contamination of formation and downhole equipment by insoluble salts, as well as salt deposits in pipeline systems. Samples prepared at a flow rate of 10-30 g/t demonstrated a high inhibitor effect in preventing calcium sulphate and carbonate deposition. Field tests of the developed salt deposition inhibitor yielded positive results.
