Prospect Analysis of Medium Low Temperature Geothermal Resource of Xizhang Area

The area is in the north subtropical coastal moist area, monsoon climate prevails, refrigeration is necessary in summer, and heating is necessary in winter.Therefore, for this area the development and utilization of shallow geothermal energy has advantageous natural conditions.In this article, through the survey methods of temperature measurement observations, we studied the distribution regularity of geothermal fields formed by various heat sources with time and space.And the geological structure of Xizhang area was further inferred, the geothermal drilling locations were determined.And then the deep strata structure, heat sources buried depth and fracture reservoir position were inferred by the controlled source earth audio electromagnetic sounding method.Finally, geothermal drilling authentication and single well geothermal resource evaluation were carried out.The results of the study indicate that the use of geothermal resources has a great future.
