摘要
This invention relates to methods for determination of thermophysical properties of porous media filled with fluid, gas, or other mineral medium, and can be used, in particular, in the oil and gas industry. When implementing the method, it is necessary to initially determine a composition of a saturated porous medium and thermal conductivity coefficients of its components. A three-dimensional image of a sample of the porous medium is obtained by X-ray scanning. A thermal conductivity coefficient of the medium is determined by solving thermal conductivity problems, based on decomposition of a computational domain followed by composition.
