| titleOfInvention | A kind of high salinity reservoirs compound oil displacement agent |
| abstract | The present invention relates to a kind of high salinity reservoirs compound oil displacement agent, the component and mass percent of its composite oil-displacing system are：Salt content 32000mg/L 360000mg/L, Ca 2+ 、Mg 2+ More than 1000mg/L highly mineralized formation brines 97.5% 99.9%, xanthans 0 0.5%, cloudy non-amphoteric surfactant 0.1% 1%, negative and positive amphoteric surfactant 0% 1%.Using the cooperative effect in highly mineralized formation brines between metal monovalence, bivalent cation, biopolymer molecule, amphoteric surfactant molecule, make the existing higher viscosity of oil displacement system, there is relatively low interfacial tension again, and steadily in the long term.Meet high salinity reservoirs and increase substantially recovery efficiency technique oil displacement system expansion swept volume, improve the requirement of oil displacement efficiency. |
