Summary:Aiming at simulating the unsteady, heterogeneous terrestrial heat field distribution with local anomalies, this article adopted unequal interval difference method to deduce the numerical solution of two-dimensional heat conduction equation. Based on the deduction, we dynamically simulate a terrestrial heat field distribution with local anomalies, where heat conductivity, density and specific heat are 1.5(W/M·°C), 2500(kg/m 3 ) and 1500(J/K·°C). The simulation shows a conclusion, that it spends 0.4 million years that the distribution recover to initial equilibrium state, which has important significance in hydrocarbon pool forming dynamics simulation and evaluation.
