Research On Influencing Factors Of Oil-water Interfacial Tension Of ASP Produced Fluid

There are many influencing factor between the crude oil of Daqing oil field and ASP solution.By using Tx500 c to measure the changing of interfacial tension with the density of alkali,surfactant,polymer and the temperature,the type of alkali to explain how ASP solution and demulsified influences the IFT.Meanwhile,the paper point out the influence of demulsified to latescence.We find that the demulsified can increase the IFT of the system with a higher concentration of alkali and surfactant but the lower concentration system is on the contrary.And it can also destroy the stability of latescence.
