Abstract: A new method for fracture prediction is proposed in this paper, to identify the distribution of carbonate fractures developed under the multi-stage stress action in the North Slope, Tazhong area. Studies show that fractures are developed in a single-azimuth set and a multiple-azimuth set in carbonate rock there. The predicted fractures with the post-stack coherent attribute are mostly distributed around faults, and developed in fault-fracture zones. These fractures are always in a multiple-azimuth set, because they are developed in two main directions by the relief of dipole-stresses. And the fractures predicted by the P-wave azimuth AVO inversion are always developed in the tops of the anticline and the uplift belt. They are always in a single-azimuth set, because they are developed by a persistent and single northeast directional stress relief. Further analysis shows that the prediction results with the post-stack coherent attribute could be used to describe the relation between fractures and faults, while the results of the pre-stack method could be used to describe the fracture distribution between faults. And the integrated prediction results not only more accurately reflect the fracture distributions, but also are consistent with the geological conditions of the North Slope in Tazhong area.

Key words： carbonate rock fracture distribution post-stack coherent attribute pre-stack azimuth AVO inversion
