- Аннотация: Acoustic anisotropy in sedimentary rock has a significant impact on seismic processing. Recent sonic processing techniques allow estimation of TIV anisotropy by obtaining shear velocity from Stoneley data. This however is often challenging and will depend on the quality of the acoustic signal, borehole and mud conditions as well as the direction of the borehole with respect to the anisotropic axes of symmetry. Combining sonic logging and sonic measurements on cores leads to a necessity to sample several plugs in different directions, rock heterogeneity interference, full size core destruction that makes the approach time-consuming and not reliable often. We combined the SonicScanner logging data with fast, non-contact non-destructive measurements of principal thermal conductivity tensor components on cores that provided a comprehensive analysis of variations in thermal and acoustic anisotropy along a well for the first time. Thermal conductivity was measured on 369 full size cores along a 60-meters interval. The study showed that both thermal and acoustic anisotropy are related to rock texture and well correlated. Moreover, analysis of thermal anisotropy was used for anisotropy characterization in intervals where well conditions did not allow estimating rock anisotropy from the sonic logging data.
