摘　　要：为了提高地热史的模拟计算精度，改进了地层热导率的计算公式和岩石骨架热导率的计算方法，讨论了地热场方程边界温度和深度的取值问题，应用大地热流的再分配原理确定了虚拟井的古大地热流，从而实现了用１口井的钻井资料和地震资料对全盆地的模拟与评价。新完钻的汤参２井所揭示的资料证明了这些改进的合理性。In order to get accurate thermal history modelling,the formula for calculating the thermal conductivities of formation and the method for computing the thermal conductivities of rock skeleton were revised; the determination of the boundary temperature and it’s depth were discussed; the paleoheat flux of fictitious wells were given by using the heat flux redistributing principle.Therefore the modelling and estimating of a basin can be carried out by using one well’s data and seismic data.The information from newly finished Tangcan-2 well showed the reasonablness of these improvements.
