Application of the system analysis for fragmentation and correlation of jurassic terrigenous sections on hydrocarbon deposits of Tomsk oblast

Abstract

The results of interpretation of a complex of logging diagrams for lithologic characteristics of a terrigenous section and allocation of marking horizons (reference points) are examined. Chronostratigraphic subdivisions in the volume of Middle-Upper-Jurassic strata by the wells of Aleksandrovskiy, Srednevasyugan, Pudinskiy and Kazanskiy oil-and-gas bearing areas of the south-east of the Western-Siberian province are allocated. The conclusion drawn, that the method of system analysis of rock associations allows to carry out correlation of polifacies sedimentary strata, tracing complete various ranked systems in time (geochronolites)
