| Abstract: | Based on the temperature data of 196 wells and measurements of 90 thermal conductivity of rocks in Junggar Basin, 35 terrestrial heat flow values are caculated. The results show that the Junggar Basin is a relatively “cold basin” now, with lower temperature and lower heat flow. Mean values of temperature gradient and heat flow are about 21.2℃/km and 42.3mW/m 2, respectively. Higher heat flow in the uplift and lower in the depression are observed. The distribution of heat flow and temperature is affected by hydrothermal circulation, structure of basement and evolution of the Junggar basin, as well as radioactive heat production in sedimentary rocks. |
