鄂尔多斯盆地地热系统

Geo-thermal Resources in Ordos Basin

本文是在前人研究基础上,结合鄂尔多斯盆地地下水勘查获取的地温资料,阐述了鄂尔多斯盆地地热形成的地质条件,大地热流的分布特征。描述了不同埋深的地温场的特征和地热梯度的空间变化规律,圈定了地下热水的分布区,利用最新的地下水资源评价的结果,概略计算了盆地的地热资源。

Based on the previous study and the geo-thermal data gathered during the implementation of the groundwate^investigation in Ordos Basin, the formation conditions of the geo-thermal resources and the distribution characteristics of the heat flux in the basin are expounded. The features of the geo-thermal filed in different depth and the spatial variation of the geo-thermal gradient are described, and the distribution zone of the geo-thermal water is located. The geo-thermal resources in the basin are basically assessed based on the updated assessment of groundwater resources for the basin.
