The paper presents the results of experimental studies of the effective thermal conductivity of gas, water and oil-filled limestone samples under high pressures up to 400 MPa and temperatures in the range of 273-523 K. It is shown that the pressure leads to a nonlinear increase of the effective thermal conductivity of limestone and affects the nature of its temperature dependence.
