Abstract：The key using multi-attribute technique for reservoir prediction is optimization of seismic attributes. It is easy to lose or mistake the selection if considering the correlation between reservoir parameters and seismic attributes only from one side to optimize the sensibility. The paper used a sensitive method that reflects reservoir parameters by appreciating seismic attributes from three aspects: effectiveness, correspondence and correlation between reservoir parameters and seismic attributes. Using sensitive attributes analytic technique and in combination with correlating cluster analytic method, the paper realized highly efficient selection of sensitive attributes feature and dimension-descending mapping. The practical application showed that the method can effectively improve the predictive effect of reservoir quantitatively.
