This paper presented an evaluation method of carbonate fractured reservoirs, which is a numerical simulation method for the an ciend structural stress field. On its basis, the authors discussed the effect of different types, of stress fields on the fractured reservoir, summed up the charcteristics of stress fields related to structural feature, and presented the method and the basic principle of predicting fracture zones, which provided the scientieic geological basis for optimally seeking well sites and increasing the rate of drilling fractures.
