The Qagan sag has the most oil and gas exploration potential among other sags in the Inggen-Ejin Qi basin,but the terrestrial heat flow research is still blank in the Qagan sag and other sags of the Inggen-Ejin Qi basin.It seriously restricts the oil and gas resource assessment in the Qagan sag.In the paper,107 rock thermal conductivity data of 19 wells were measured and in-situ corrected,and the rock thermal conductivities of each stratum were obtained by Union average formula.Based on the 9 wells＇ temperatures,combined with the above rock thermal conductivity data,the geothermal gradient and terrestrial heat flow data were calculated.The results show that the Qagan sag has the characteristics of medium temperature field in between tectonically stable and active regions,with an average thermal gradient value of 33.6 ℃/km and an average terrestrial heat flow value of 74.5 mW/m2.The paper provides the geothermal data for oil and gas resource assessment of the Qagan sag and other sags of the Inggen-Ejin Qi basin.
