Abstract: Strong heterogeneity is a problem in the exploration in fracture and vug zones of carbonate formations in the Xinjiang oil work region. In this study, we developed a method based on information fusion of seismic multi-attributes optimized and electric image well logging, then applied it to identify and evaluate the fracture and vug zones existed in carbonate formations,and further to optimize the borehole tracks in carbonate reservoirs. First, we predicted and sculptured the spatial distribution of fractures and vugs by using the information derived from the multiple seismic attributes of coherence, ant tracking, and others in combination with the result of pulse inversion constrained by dip vectors to determine the scope of the potential hydrocarbon trap; Second, the orientation and dip of the fractures and the scattering of the vugs were statistically estimated through the information automatically picked up from the borehole electric images by means of mathematical morphology filtering; Third, the orientations of maximum and minimum stresses in the formations were estimated through the information of borehole collapse deduced from the multi-arm dipmeter logs and the drill bit induced fractures extracted from the electric image well logs; Furthermore, the results of fracture distribution and vug scattering were obtained through information fusion of multiple seismic attributes and electric images, which can be used as an indicator of the orientation of the maximum stress in regional slipping faults. The orientation of the maximum stress in this region is directed to NE-SW, locally directed to NW-SE, and the fractures with medium-high dip are along the maximum stress direction. Based on the predicted maximum stress, the optimization borehole track of deviated borehole and horizontal well was designed along the direction of NW-SE. In application, the drilled boreholes penetrated large scale high quality reservoirs, and obtained stable amount of oil production. Also, by using this method, the risk of deep formation exploration can be significantly decreased.

Key words: fractured and vuggy carbonated reservoirs, seismic attributes, electric imaging well logging, evaluation of the fractured and vuggy zones, optimization of borehole track
