Abstract

Способ обслуживания скважины в подземном пласте, включающий получение инвертированной эмульсии, содержащей водную жидкость, маслянистую жидкость и эмульгирующую композицию (ЭК), при этом эмульгирующая композиция содержит эмульгатор, разбавитель и понизитель вязкости, и понизитель вязкости содержит спирт, амид жирной кислоты или их комбинации; и размещение инвертированной эмульсии в скважине. Способ обслуживания скважины в подземном пласте, включающий прокачку жидкости для обслуживания скважины, содержащей эмульгирующую композицию (ЭК), через часть подземного пласта, при этом ЭК содержит эмульгатор, разбавитель и понизитель вязкости, и понизитель вязкости содержит 2-метил-1-пропанол, 2-метил-2-бутанол, амид жирной кислоты или их комбинации; приведение в контакт ЭК с нефтью in situ в пласте с образованием эмульсии; и уменьшение межфазного натяжения между водой и нефтью, и изменение смачиваемости с обеспечением увеличенной нефтеотдачи пласта.
