Abstract
Изобретение относится к наноэмульсии с масляной внешней фазой и внутренней фазой в форме сложного водного раствора, обладающей замедленным действием и содержащей неорганические и/или органические кислоты; указанная наноэмульсия пригодна для обработки и стимуляции пластов-коллекторов углеводородов и термальных вод и для очистки оснований скважин. Более конкретно, настоящее изобретение относится к наноэмульсии, содержащей сложный водный раствор в качестве эмульгированной фазы в органической дисперсионной среде, как определено в данной публикации, причем эмульгатор является поверхностно-активной смесью неионогенных поверхностно-активных веществ, определенных в данной публикации, которая образуется в межфазном слое на границе раздела фаз, и этот межфазный слой обеспечивает кинетическую стабильность наноэмульсии. Наноэмульсия содержит в эмульгированной водной фазе одно или более соединений, описанных в данной публикации, для применения ее в качестве стимулятора пластов, в частности - кислоту, повышающую проницаемость горной породы, или смесь кислот, необязательно ингибитор коррозии, агент, связывающий Fe3+ ионы, и ингибитор набухания глин.The invention relates to a nanoemulsion with an oily external phase and an internal phase in the form of a complex aqueous solution with a delayed action and containing inorganic and / or organic acids; the specified nanoemulsion is suitable for the treatment and stimulation of hydrocarbon and thermal water reservoirs and for cleaning the bottom of wells. More specifically, the present invention relates to a nanoemulsion containing a complex aqueous solution as an emulsified phase in an organic dispersion medium as defined in this publication, the emulsifier being a surfactant mixture of nonionic surfactants as defined in this publication, which is formed in an interfacial layer at the interface, and this interfacial layer provides the kinetic stability of the nanoemulsion. The nanoemulsion contains in the emulsified aqueous phase one or more of the compounds described in this publication for use as a formation stimulator, in particular an acid that increases the permeability of a rock, or a mixture of acids, optionally a corrosion inhibitor, an agent that binds Fe3 + ions, and an inhibitor swelling of clays.
