Estimating Thermophysical Rock Properties from Electromagnetic Sounding Data and Laboratory Measurements

摘要

Possibilities to construct the sections of thermal conductivity, specific heat capacity, as well as heat flow density at the surface, using electromagnetic sounding data and laboratory measurements on core samples, have been studied. It has been shown that the neural network prediction of thermophysical properties from electromagnetic sounding data and laboratory measurements enables estimat-ing these properties not only below boreholes but also in the interwell space, with relative accuracy around 6-10. Sections of "dry" and "wet" thermal conductivity, specific heat capacity and a profile of the heat flow density at the surface of the study area, along magnetotel-luric sounding profile, have been built.
