Abstract

For intensification of the imbibition process of porous systems and for displacing liquids by other liquids, particularly in secondary oil production, the polycomplexes based on synthetic polyelectrolytes and non-ionic surfactants are of interest. The surface activity of solutions of composite systems based on polyethyleneimine (PEI) and ethoxylated isooctylphenol (OP-10), PEI and ethylene and propylene oxide block copolymer in pure and mineralized water at the water/air, water/oil interfaces have been studied. In comparison with pure water, a medium salinity causes the increase of solutions surface tension of the surfactants and their mixtures with PEI by 2-4 mJ/m2. The surface tension value increases weakly (by 1-4 mJ/m2) under the mineralization of water. At increased relative concentration of OP-10, ethylene and propylene oxide block copolymer, patterns of surface tension change are similar to those ones in pure water. The wetting action of salt solutions of PEI and block copolymer on the oil substrate formed on the glass plate surface was established.
