Fractured reservoir exploration has great potential, and its development is affected by many factors, so it is necessary to describe it by combining geology, well logging, geophysical data and other information. Through meticulous analysis on the geological data of the lower Shasan member reservoir in Bonan sag and multi-scale fracture prediction, we selected two kinds of technologies: one is using tomographic image enhancement technology to predict fracture zone and another is using multi-attribute trend fitting technique to predict the planar distribution of the first class reservoir. However, there is a big uncertainty of the prediction result whenusing only a single technology, so it is necessary to combine these two kinds of prediction techniques and use overlay display technology to predict the advantaged fracture reservoir zone in the study area, which can improve the prediction accuracy of fractured reservoirs. We combined the structural dip attribute of the lower Shasan member reservoir with the predicted thickness of the first class reservoir. The results show that the fault zone Yi182 and the southern Luo42 well around are favorable target zones, where the field drilling high-producing wells such as Yi182, Yi186 and Yi187 well etc. show good indication of oil and gas. Well Boye-Ping1 is located near the favorable fractured reservoir zones which are predicted by combining display technologies, and it shows that the application of combining display technologies can improve reservoir prediction accuracy, which is an effective method of comprehensive evaluation of fractured reservoirs.
