| Based on a wide range of research, the accumulation of overseas work and theoretical study, the research objects are two carbonate oil fields, one is Zhanazhol, Kenkiyak oilfields located at the east part of Precaspian Basin, western Kazakhstan, and the other Yurubcheno-Tokhomskoye oilfields located at the west of Baykit Basin in Eastern Siberia. According to the geological, geophysical, logging and other basic information, we use observation, laboratory studies, theoretical analysis, numerical simulation, general information analysis by GIS data, then analyze the morphological description, cause analysis, and the development mechanism of reservoirs in such areas. We conduct a comprehensive study, trying to establish a quantitative evaluation system on fractured reservoirs and synthetical evaluation on multivariate fractures. The results of studies are the following:①Set up general evaluation techniques on fractured carbonate reservoirs, based on the integrated exploration and development system and GIS;②propose ideas and methods for applying gravity and magnetic information and for interpreting remote sensing technology on fracture;③propose the extraction and analysis techniques on the fractures information, using structure data based on DEM;④built up both a three-dimensional geological model of the fractured reservoirs and their simulation conduction paths on GIS;⑤Use multiple information technology of cracks for Yurubcheno-Tokhomskoye oil field's evaluation on fractured reservoir, forecast high-yield zone, and complete the comprehensive analysis of cracks' multiple information under different scales and spatial relationships.
