Abstract

The relevance of the discussed paper is related to a national objective of increasing a gain of stocks of hydrocarbonic raw materials and bad geological study of the Lower-Middle Jurassic deposits of the Southeast of Western Siberia. The main aim of the research consists in complex studying of geological structure of the Lower-Middle Jurassic layers on the territory of Tomsk region as well as in defining the perspectives of oil-and-gas zones caused by the secondary processes. The authors have used the traditional methods of lithological and stratigraphy correlation of cuts of wells on the materials of well logging, descriptions of results of petrographic analysis of shlif on the base of «Affairs of wells», and the innovative statistical interpretation method of the GIS date regarding the identification of low-impedance hydrocarbonic saturated collectors and intensity of the secondary geochemical processes. The paper introduces the results of generalization of a geological structure and stratigraphy of the Lower-Middle Jurassic deposits of the Tomsk region. Oil and gas complexes were allocated and on the base of empirical data the prospects in formation of hydrocarbon deposits of each complex were shown. The intensity of the secondary processes and probability formation of low-resistance collector were based on the innovative statistical interpretation method of the GIS date. The authors determined the areas of higher perspective in Lower-Middle Jurassic deposits. The results. Nadoyakhsky and malyshevsky complexes are the most perspective oil and gas companies in the Lower-Middle Jurassic deposits of the Tomsk region, in case of detection of impermeable layers and traps. The most perspective areas (from the point of view of detection of the low-impedance hydrocarbonic saturated deposits) are within the territories of interstructural zones, or the ones close located to them. Lateral correlations between the samplings of the average data (on a section) of kaolinization intensities with a low-impedance parameter, carbonization and pyritization with porosity allow revealing the formation modes, or destructions of hydrocarbonic deposits.
