FIELD: data processing.
SUBSTANCE: invention relates to geophysics and can be used for investigation of underground structures. Disclosed is method of estimating distribution of temperature in geologic environment based on three-dimensional model of thermal conductivity for geologic bed. According to proposed method, measured data corresponding geological underground formation of interest containing data of seismic exploration, downhole temperature, heat flow measurement at bottom and on sea surface and core porosity laboratory measurements. Dependence between seismic wave velocity and heat conductivity is estimated. At that, seismic wave velocity is linearly dependent on porosity and heat conductivity is exponentially or linearly dependent on porosity. Said model is calibrated based on said measured borehole data and porosity of core laboratory measurements.
EFFECT: higher accuracy and reliability of results of simulation.
