Abstract
1. Способ подготовки дистиллерной жидкости к закачке в нефтяные пласты, включающий отстаивание при охлаждении до 60 - 90C исходной щелочной дистиллерной суспензии, отделение шлама, последующее охлаждение осветленной щелочной дистиллерной жидкости до температуры -10 ± 25C, карбонизацию суспензии до рН 7,2 - 9,2, смешение и направление ее на закачку в нефтяные пласты, отличающийся тем, что, с целью повышения нефтеотдачи продуктивных пластов, охлажденную прокарбонизированную дистиллерную жидкость подвергают обработке постоянным электрическим током объемной плотностью заряда не менее 100 Кл/дмв течение 10 - 30 с с одновременным разделением ее на два потока с рН > 11 и рН < 7, после чего поток с рН < 7 смешивают с осветленной щелочной дистиллерной жидкостью в соотношении от 1 : 10 до 1 : 3.2. Способ по п.1, отличающийся тем, что поток с рН < 7 закачивают в продуктивные пласты.1. The method of preparing distiller fluid for injection into oil reservoirs, including settling the initial alkaline distiller suspension while cooling to 60 - 90C, separating the sludge, then cooling the clarified alkaline distiller fluid to -10 ± 25C, carbonizing the suspension to pH 7.2-9 , 2, mixing and its direction to injection into oil reservoirs, characterized in that, in order to increase the oil recovery of productive formations, the cooled procarbonated distiller fluid is subjected to a constant electric current treatment m bulk charge density of at least 100 C / dmv for 10-30 seconds while simultaneously splitting it into two streams with pH> 11 and pH <7, after which the stream with pH <7 is mixed with clarified alkaline distiller liquid in a ratio of 1: 10 before 1: 3.2. The method according to claim 1, characterized in that a stream with a pH <7 is pumped into productive formations.
