Abstract: In this paper, 10 terrestrial heat flow values have been derived from logging data of 65 wells samples, and heat conductivity from 43 core sam-ples. It is shown that general aspect of the geothermal field is distributed in a ring-like form. An attempt to analyze the factors affecting such a distribution is made also. The Songliao Basin has an excellent geological background of lacustrine sedimentation and rich in oil-producing materials. In addition, a relatively high geothermal field exists in this area. Therefore, it is very favorable to the formation of oil-gas field. The result of analysis has revealed some relations between the forma-tion of oil-gas field and the tectonic structure of Songliao Basin, as well as the relation between the migration and accumulation of oil-gas and the geothermal field.
