Abstract: The study is focused on the largest carbonate rock oil and gas field in the southern part of East Siberia -- Yurubcheno-Tokhomskoye Oil and Gas Field. Based on geological and geophysical data and backed by GIS system, the study adopts the comprehensive analysis method for multi-element information to scrutinize the information on the fractures of different sizes in the carbonate rock oil field in the light of fractural origin and development laws. The seismic data are used to identify regional Riphean reservoir development zone and predict fractural development zones caused by structural fractures of different sizes. The Riphean fractural reservoir is brought under comprehensive evaluation for the purposes to determine the principle for classification of reservoir-appraising factors, establish the database of multielement fracture information that influences reservoir development, build thematic map by means of space analysis model, and conduct topological calculation and drawing. The high-yield zone is predicted on the basis of the above-mentioned work in the efforts to make a comprehensive analysis of the information on multi-element fractures of different sizes and space relations. The advantages of this method are to maximize collection of various fractural information, establish a magnitude database of relative information, and facilitate rapid selection and comparison of information and thematic space analysis. This study makes full use of geological characteristics of oil and gas fields and wisdom of experts and optimizes fractural information to effectively serve actual production of oil fields
