摘　　要：分别采用一维和二维热传导数学模型,对漳州盆地典型区域深部温度进行了数值模拟,并进行了热储量的初步估算。首先由实测样品数据得到地表生热率和热导率等参数,再由所得地表生热率计算深部生热率,依据地球物理勘探解释结果,给出地层结构和厚度等参数。然后分别利用一维分层热传导模型和二维稳态热传导模型进行数值模拟,得到不同条件下5 000 m以浅不同深度的温度值。最后基于数值模拟参数,给出了研究区分层热储量的计算结果。This paper simulates the deep rock stratum temperature of the typical area in Zhangzhou basin by nu- merical method of one-dimensional and two-dimensional heat transfer mathematical model. And the heat storage capacity is preliminary estimated. First the parameters such as thermal conductivity, heat production rate of the surface are obtained by the measured sample data. And the heat production rates of deep area are computed by the heat product rate on surface of the area. According to the results of geophysical interpretation, formation parame- ters such as structure and thickness of the formation are given. Then some numerical simulation results of tempera- ture value are obtained in different depth of the shallow above 5000 meters under different conditions by using one- dimensional layered heat conduction model and the two-dimensional steady-state heat transfer model, respectively. The layered heat storage capacity are estimated in the typical area based on the parameters by numerical simula- tion.
