Application of real-time fiber optic transmission technology for dynamic monitoring of geothermal temperature
In order to balance between extraction and injection of geothermal resources during development and utilization,dy-namic monitoring of geothermal wells is required.Based on distributed optical fiber real-time transmission technology,this study conducts dynamic monitoring of geothermal wells in Xiong'an New Area to reveal the characteristics of temperature and dynamic evolution for thermal reservoirs.The research results show that optical fiber real-time transmission technology can significantly improve the efficiency and accuracy of geothermal temperature monitoring,thus providing powerful support for the development of geothermal energy.The geothermal gradient of the geothermal well can reach 5.33 C/100,thus with good geothermal condi-tions.Due to the thermal recovery characteristics during the non-heating period,the reservoir temperature will first rise to a cer-tain extent and then stabilize.From the perspective of reservoir depth and time evolution monitored by optical fiber,the tempera-ture of the reservoir will decrease during the heating period due to the exploitation of other geothermal wells.This optical fiber real-time transmission technology can achieve low-cost and high-efficiency for dynamic temperature measurement,and can be further extended to other geothermal field monitoring.
