Способ относится к нефтедобывающей промышленности. Для снижения токсичности ингибитора адсорбции ПАВ используют 1 - 3%-ные водные растворы лигносульфонатов. Раствор лигносульфонатов подают в пласт перед нагнетанием раствора ПАВ. Лигносульфонаты, получаемые из отходов спиртового и дрожжевого производства, представляют собой нетоксичные продукты.The method relates to the oil industry. To reduce the toxicity of the surfactant adsorption inhibitor, use 1 - 3% aqueous solutions of lignosulfonates. The lignosulfonate solution is fed into the reservoir before injecting the surfactant solution. Lignosulfonates derived from alcohol and yeast production wastes are non-toxic products.
