Аннотация:Quality of rock thermal property data is the crucial question in hydrodynamic and basin and petroleum system modeling. Numerous measurements of thermal properties (thermal conductivity, thermal anisotropy coefficient and volumetric heat capacity) performed on more than 11 000 core samples with the thermal core logging in 2014-2016 allowed us to form a representative database of the Bazhen formation thermal properties. Our previous data from the measurements performed in 1993-2014 within the Continental Super-Deep Drilling Program (Russia) for scientific super-deep well Tyumenskaya SG-6, parametric super-deep well Yen-Yakhinskaya SG-7, and deep well Yarudeyskaya-38 as well as for 13 oil and gas fields in the West Siberia are combined with the new experimental data within the thermal property database. Variations of the thermal conductivity tensor components in parallel and perpendicular direction to the layer stratification (assessed for 2D anisotropy model of the rock studied), volumetric heat capacity and thermal anisotropy coefficient values and average values of the thermal properties were the subject of statistical analysis for the uppermost deposits aged by: T3-J2 (200-165 Ma); J2-J3 (165-150 Ma); J3 (150-145 Ma); K1 (145-136 Ma); K1 (136-125 Ma); K1-K2 (125-94 Ma); K2-Pg+Ng+Q (94-0 Ma).
