Abstract(summary):

Oil component and molecule structures is studied by application of gas chromatogram, infrared spectrum and nuclear magnetic resonance to develop high efficiency and cost effective surfactant used for chemical flooding, HZS surfactant has been developed on basis of relationship between effectiveness and structure of the surfactant. Study on surfactant structure characterization and performance evaluation suggests that oil/water interfacial tension is super low when distribution of carbon number of main component of surfactant is identical to the distribution of main component of oil, and concentration impairment due to surfactant retention on surface of core. Reference can be provided to reservoir selection and surfactant development of other oilfield.
