摘要
探讨地温场特征,通常采用钻孔系统测温的方法。依据平庄盆地北部地温场的特征,采用先进的ANSYS大型通用有限元分析软件数值模拟的方法,对基底和盖层内的大地热流传导和地温场特征进行了数值模拟。可视化的模拟结果直观揭示了在盆地基底坳陷充填盖层、盆地外围基底秃顶配置的条件下,大地热流自盆地基底至盖层内重新再分配的特点,地温等温线受此影响在剖面呈上凸状,根据得到的地温数据计算并绘制了盆地北部基底顶面地温等值线图。
The conventional method of exploring the ground temperature field consists of roundly measuring ground temperature. The paper highlights the substitutable method of numeric simulation of the conduction of geothermal flux and ground temperature field in basement and sedimentary cover, depending on the advanced and powerful finite element analysis software ANSYS, as determined by the study of the characteristics of ground temperature field in the north of Pingzhuang basin. The visual simulation results present intuitive indication that the geothermal flux is redistributed from basement to cover and that the isotherms subjected to influence of the redistribution take on convexity, due to the configuration of upheaval and depression of basement with sedimentary cover and basement out of the basin without sedimentary cover. An isotherm graph on the surface of basement in the north of basin is drawn depending on the temperature data obtained.
