The unstable layer of Aihu oilfield is characterized by strong hydration dispersion and weak expansion. The theory of multiple synergistic wall stabilization was applied to improve synergistic efficiency of the drilling fluid. The recipe of multiple synergistic drilling fluid is worked out. The multiple synergistic drilling fluid was evaluated by analysing the rheology, filtration, wall building, inhibition for the borehole & the weak layers. The inhibition and rheology of the tested drilling fluid system is as good as anti-temperature performance. The ternary-inhibitive drilling fluid system is superior to the binary-inhibitive drilling fluid system. The ternary-inhibitive contained in the multiple synergistic drilling fluid system enhances the ability of water dispersion inhibition. The application of Aihu oilfield shows that the multiple synergistic drilling fluid has satisfied the requirements of low filtration and slight wall expansion.
