Abstract
It is vital importance to understand distribution and development of carbonate reservoir fractures for studying carbonate reservoir. Stimulate and acceptance conditions of study area in the desert are poor, and The seismic data is characterized by narrow azimuth. Limit of data has influence on fracture prediction of target layer. In this paper, the post-stack and pre-stack seismic data were used. At first , techniques of stress field numerical simulation was applied to predict the distribution of tectonic crack of the study area ; Secondly, because of the characteristics of narrow-azimuth seismic data, the paper applied technology of near and far offset attribute discrepancy of pre-stack data to predict the degree of development of cracks. Finally, effective fracture was predicted on the basis of development of the forecasted cracks.
