FBG Sensing Technology for the Temperature Monitoring of Geothermal Wells
Geothermal energy has been gaining popularity in the new energy industry due to its reliability and sustainability. However, to ensure the efficient and safe operation of geothermal wells, temperature monitoring is crucial. Temperature changes in the wellbore and the surrounding formations can provide valuable information about the geothermal resource and the well's integrity. Fiber grating sensing technology has proven to be a promising solution for temperature monitoring in geothermal wells. In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can help to monitor the temperature of geothermal wells in the new energy industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

The Situation of Geothermal Energy in the New Energy Industry：
Geothermal energy is a clean and renewable source of energy that can provide a reliable and stable source of electricity. According to the International Energy Agency, the geothermal power capacity has been steadily growing, with a total installed capacity of 14.9 GW in 2020. The United States, Indonesia, and the Philippines are the top three countries in terms of geothermal power generation.
Why Temperature Monitoring of Geothermal Wells is Needed：
Temperature monitoring of geothermal wells is critical for ensuring the efficient and safe operation of geothermal power plants. The temperature changes in the wellbore and the surrounding formations can provide valuable information about the geothermal resource and the well's integrity. Accurate temperature measurements can help optimize the operation of geothermal power plants, reduce maintenance costs, and prolong the lifespan of the well.
Difficulties in Temperature Monitoring of Geothermal Wells：
Temperature monitoring in geothermal wells presents several challenges. Geothermal wells operate at high temperatures and pressures, which can damage the sensors and affect their accuracy. The corrosive and abrasive nature of geothermal fluids can also damage the sensors and cause measurement errors. Additionally, the harsh environment of geothermal wells can make sensor installation and maintenance challenging and costly.
What Problems can be Solved by FBG Technology：
Fiber grating sensing technology has several advantages that make it a promising solution for temperature monitoring in geothermal wells. FBGs are highly durable and can operate at high temperatures and pressures, making them suitable for the harsh environment of geothermal wells. The small size of FBGs makes them easy to install and integrate into existing wellbore completion systems. Furthermore, FBG sensors can provide accurate and real-time temperature measurements, enabling operators to optimize the operation of geothermal power plants and ensure the integrity of the well.
