The invention relates to the field of technologies for extracting oil from high-turn steam-stimulated wells, in particular to a multi-element composite water-control oil-enhancement method for extracting oil. The multi-element composite water-control oil-enhancement method includes steps of firstly, injecting 0.15-0.3 PV of nitrogen into shafts at the nitrogen injection speeds of 1.5*10<4>-3*10<4> m<3>/d, enabling the nitrogen to force water in the shafts to flow towards the bottoms of the shafts, reducing the edge and bottom water coning speeds and enabling the nitrogen to displace bottom water to flow into water outlet passages to form nitrogen cavities; secondly, injecting water-base plugging agents with the mass percent concentration of 0.5%-1% into the shafts at the water-base plugging agent injection speeds of 15-30 m<3>/h. The multi-element composite water-control oil-enhancement method has the advantages that diversified injectants are effectively combined with one another to be injected into target strata, accordingly, steam channeling passages can be effectively plugged, steam absorption profiles can be adjusted, stratum pressures can be increased, the viscosity of crude oil can be reduced, the flowability of the crude oil can be improved, development effects of high-turn stimulated wells can be ultimately enhanced, and recovery ratios of the high-turn stimulated wells can be increased.
