Abstract

The emulsifying characteristics research of the produced liquid in weak base alkaline-surfactant-polymer lay the theoretical foundation for the process ofoil-water separation and the choice of operating parameters, this paper mainly researchs the degree of emulsification of produced fluid, the properties of electrostatic double layer and interfacial tension. Studies have shown that the emulsified state of produced fluid is complex, it shows the coexistence of multiple emulsion, the average granul diametre of internal phase in emulsion fluid is 4.48-7um, and the thickness of boundary mask increases until the maximum thickness reachs to 2.5um ~ 3.75um; the Zeta potential in diffuse electric double layer of charged ions is between -30mV ~ -50mV; the boundary mask of produced liquidis always between 0.01 ~ 1 mN / m, less than the oil/water interfacial tension of the produced liquid in strong base alkaline-surfactant-polymer.The stability of emulsion is good, and not conducive to oil-water separation.
