三元复合体系在多孔介质运移过程中变化规律研究

Abstract

Abstract:

In order to further explore the migration rule of alkali/surfactant/polymer（A/S/P） system in the reservoir, guided by the reservoir engineering, surfactant chemistry and oilfield chemistry, and aimed at the fluid properties and geological characteristics, we conducted the research on change rule of viscosity, IFT tension and displacement effect of A/S/P system, and discussed the relative mechanism based on the dynamic testing result of single component concentration of compound system. The results showed that during the displacement process of A/S/P system, the polymer, surfactant and alkali presented different along-range retention characteristics, the chromatographic separation phenomenon occurred, the decrease rate of surfactant concentration was much higher than that of polymer and alkali, and both the ultra-low interfacial tension and high viscosity could only keep the length of 1/3 well distance. The contribution rate of ultra low tension was limited in the A/S/P flooding; about 60 % oil was not recovered by compound system under the condition of ultra low tension. If the A/S/P system can keep lower IFT and give consideration to proper viscosity, we can acquire the better displacement effect.

Key words: alkali/surfactant/polymer（A/S/P） compound flooding, component concentration, viscosity, interfacial tension, displacement effect
