| Zusammenfassung |
| Quality of heat flow and rock thermal property data is the crucial question in basin and
petroleum system modeling. A number of significant deviations in thermal conductivity
values were observed during our integral geothermal study of West Siberian platform
reporting that the corrections should be carried out in basin models. The experimental data
including thermal anisotropy and heterogeneity measurements were obtained along of more
than 15 000 core samples and about 4 500 core plugs. The measurements were
performed in 1993–2015 with the optical scanning technique within the Continental
Super-Deep Drilling Program (Russia) for scientific super-deep well Tyumenskaya SG-6,
parametric super-deep well Yen-Yakhinskaya, and deep well Yarudeyskaya-38
as well as for 13 oil and gas fields in the West Siberia. 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). Uncertainties
caused by deviations of thermal conductivity data from its average values were
found to be as high as 45 % leading to unexpected errors in the basin heat flow
determinations.
Also, the essential spatial-temporal variations in the thermal rock properties in the study
area is proposed to be taken into account in thermo-hydrodynamic modeling of hydrocarbon
recovery with thermal methods.
The research work was done with financial support of the Russian Ministry
of Education and Science (unique identification number RFMEFI58114X0008). |
