| Abstract: | The author revealed the structural form of basement and the location of the fault zone of the Tertiary fault basin in Lanzhou by means of regional gravitation exploration; Predicted the abnormal geothermal distribution area using hydrogeochemical geothermal thermometric scale of SiO_2 and predirect temperature test in wells. The author points out the position of geothermal reservoir through the analysis of the logging material from a deep borehole located in the yard of the factory of petroleum and chemical engineering in Lanzhou. The foreground of geothermal resources and the advantageous region for exploration were provided. |

| Keywords: | regional gravitation geothermal exploration basement structural form faulted structure analysis of geothermal reserves. |
