Abstract：In order to objectively reflecting the feature of seismic wavefield in fractured reservoir,the paper,on the basis of predecessors' studies,presented a new numeric simulation method of fractured reservoir-Micro Vector and Macro Scale (MIVMAS).The method comprehensively considers the physical properties of fractures and surrounding materials in fracture-developed zones and uses micro Christoff vector equations to compute P-wave-equivalent velocity in each fracture-developed zone,which obtains new velocity model and the model of reflection coefficients; then,using numeric simulation method of wave equation,the numeric simulation of new model is carried out by macro scalar wave equation.Taking the whole feature of fracture zone as studied target,the results of numeric simulation obtained by the method are more consistent with reality,which provides a new idea and method for study of wavefield feature in fractured reservoirs.
