摘要

Preliminary geothermal surveys to identify areas of potential geothermal anomalies are the most important stage in traditional hydrothermal-type geothermal resource exploration procedures. Temperature gradient wells are limited because of their accessibility issues and high costs, whereas the 2 m survey is considered a rapid, efficient, and inexpensive method to measure temperature accurately and allow for rapid vectoring toward geothermal anomalies in cases where thermal groundwater is not overlain by near-surface cold aquifers. An improved quick and portable measurement device is developed that adds in situ thermal conductivity tests based on temperature. The device, which is easy to assemble, portable, and suitable for two or three people in field work, had been calibrated by laboratory experiments. This study will use this improved survey device in Xiamen City in China and combine an in situ thermal conductivity analysis with a temperature inverse forecast to increase preliminary geothermal survey accuracy and provide survey experience for other similar potential geothermal fields in China.
