根据现个地温梯度及镜质体反射率测定结果,反演了鄂尔多斯盆地现今大地热流分布,在综合研究盆地古、今地热场特征的基础上,对地热场的影响因素进行了统计分析,并指出了主要影响因素的特点.结合构造—沉积演化史,探讨了盆地不同阶段、不同地区的有机质成熟史.

On the basis of present geothermal gradient and vitrinite reflectance in the Ordos basin, present geothermal flux was inversed. According to characteristics of paleo-and present geothermal field of the basin, the infleuntial factors were analysed in statistic way and properties of the main infleuntial factors were pointed out. In accompanying with study of tectono-depositional evolution,maturing history of organic matter in different stages and areas of the basin were analysed.
