Present Geothermal Field of the Chagan Sag in the Yingen-Ejinaqi Basin of Inner Mongolia, NE China
View through CrossRef
Abstract
The aim of this work is to discuss the present geothermal field of the Changan sag of the Yingen-Ejinaqi Basin in Inner Mongolia, NE China. In this study, the rock thermal conductivity and heat generation of the Chagan sag were tested, and the geothermal gradient of four wells and the first heat flow data were calculated. It is concluded that the geothermal gradient of the Chagan sag can be divided into three sections, i.e., K2
w-K1

2. The heat flow of the Chagan sag is 70.6 mW/m2, indicating that this sag is in a geothermal state between tectonic active area and tectonic stable area. The results may provide significant geothermal information for the evaluation of geothermal resources in the Chagan sag.
