Изобретение относится к нефтедобывающей промышленности, в частности к обработке скважин и призабойной зоны нефтяного пласта. Изобретение обеспечивает получение эффективного состава для обработки скважины и(или) призабойной зоны пласта и способа обработки скважины и(или) призабойной зоны пласта. Для этого состав для обработки скважины и(или) призабойной зоны пласта включает, мас. %: биоценоз углеводородокисляющий бактерий - 0,08 - 0,2, соли диаммонийфосфат и ацетата натрия - 0,1 - 0,2 и воду. Для стимуляции роста микроорганизмов состав дополнительно содержит биостимулятор: натрия бикарбонат - 0,05 - 0,1% или аммонийную соль янтарной и уксусной кислот или дезоксирибонуклеазу - (8,5 - 10)10- 5%. Способ обработки скважины и(или) призабойной зоны пласта включает закачку предлагаемого состава. При обработке призабойной зоны пласта после закачки состава проводят выдержку в течение 5 - 7 дней, а при обработке скважины и призабойной зоны пласта предлагаемый состав циркулирует по системе насосно-компрессорные трубы - затрубное пространство в течение 5 - 7 суток. Для улучшения жизнедеятельности микроорганизмов состав перед закачкой в скважину и(или) призабойную зону пласта предварительно аэрируют.The invention relates to the oil industry, in particular to the treatment of wells and the bottom zone of the oil reservoir. The invention provides for obtaining an effective composition for treating a well and / or a bottomhole formation zone and a method for treating a well and (or) a bottomhole formation zone. To do this, the composition for treatment of the well and (or) the bottomhole formation zone includes, by weight. %: hydrocarbon-oxidizing biocenosis of bacteria - 0.08 - 0.2, salts of diammonium phosphate and sodium acetate - 0.1 - 0.2 and water. To stimulate the growth of microorganisms, the composition additionally contains a biostimulator: sodium bicarbonate - 0.05 - 0.1% or ammonium salt of succinic and acetic acids or deoxyribonuclease - (8.5 - 10) 10 - 5 %. The method of treatment of the well and (or) the bottomhole formation zone includes the injection of the proposed composition. When processing the bottomhole formation zone after injection of the composition, hold the exposure for 5 to 7 days, and when processing the well and the bottomhole formation zone, the proposed composition circulates through the system tubing - annulus for 5 to 7 days. To improve the vital activity of microorganisms, the composition is aerated prior to injection into the well and (or) the bottomhole formation zone.
