BASIN MODELING OF HYDROCARBON SYSTEMS IN THE SOUTHWEST OF THE TOMSK REGION (NYUROLKA MEGADEPRESSION AND ADJACENT TERRITORIES)

M. O. Zakhryamina

Using the Schlumberger’s PetroMod software, the author has forecasted the time of hydrocarbon generation and migration from source rocks in the conjunction zones of the Nyurolka megadepression with positive first order structures, with estimation of the most probable occurrence of potential traps and pools of hydrocarbons in the cross-section. As a result, a model was built which shows and proves a possibility of accumulation of gaseous and liquid hydrocarbons in the Upper Jurassic sand deposits of U1 horizon due to oil and gas generation in the Lower-Middle Jurassic and Upper Jurassic Bazhenov source rocks. The largest modelled accumulations spatially coincide with the existing hydrocarbon pools in the Nyurolka petroleum region and adjacent territories, which justifies the modelling performed. The differences between existing and modelled pools imply that there is a lithological factor that affects pool configuration or possible modelling inaccuracy.

Key words: deposits, facies, hydrocarbon pools, modelling, source rock, generation, accumulation.
