What to think about geothermal pressure: analysis of hot topics on the Internet in the past 10 days
Recently, geothermal energy and related geological issues have become the focus of public attention, especially the monitoring and application of geothermal pressure, which has triggered widespread discussion. This article combines the hot topics on the Internet in the past 10 days and uses structured data analysis to explain the key points of geothermal pressure for you.
1. List of hot topics in the geothermal field in the past 10 days
| Ranking | Topic keywords | heat index | Main discussion platform |
|---|---|---|---|
| 1 | Geothermal power generation technology breakthrough | 9.2 | Zhihu, science forum |
| 2 | Geothermal pressure monitoring method | 8.7 | Industry media, B station |
| 3 | Geothermal heating system failure | 7.9 | Weibo, Tieba |
| 4 | Geothermal field development controversy | 7.5 | news client |
2. Core observation indicators of geothermal pressure
According to the latest data from the China Geological Survey, geothermal pressure assessment needs to focus on the following parameters:
| Parameter name | normal range | danger threshold | measuring tools |
|---|---|---|---|
| pore pressure | 0.8-1.2MPa | >1.5MPa | pressure sensor |
| temperature gradient | 30-50°C/km | >80°C/km | Thermocouple |
| Fluid flow rate | 5-15m/s | >25m/s | flow meter |
3. Typical cases of geothermal pressure anomalies
The pressure fluctuation incident in the Yangpajing geothermal field in Tibet has recently caused heated discussion. Monitoring data shows:
| Date | Pressure value (MPa) | Temperature (°C) | abnormal characteristics |
|---|---|---|---|
| May 10 | 1.28 | 152 | normal |
| May 15 | 1.67 | 189 | sudden increase in pressure |
| May 20 | 1.42 | 163 | Gradually fall back |
4. Three major technical trends in geothermal pressure monitoring
1.Internet of things real-time monitoring system: Data is transmitted back every minute through the 5G network, and the early warning response time is shortened to within 30 seconds.
2.AI prediction model: The deep learning algorithm developed by the Tsinghua University team can predict pressure abnormalities 72 hours in advance with an accuracy of 89%.
3.Distributed fiber optic sensing: New DTS technology can realize continuous temperature/pressure monitoring of the entire wellbore, reducing costs by 40%.
5. Expert advice and public response guidelines
The Geothermal Special Committee of China Energy Research Association made the following suggestions:
| Target group | Countermeasures | Things to note |
|---|---|---|
| development enterprise | Establish a three-level early warning mechanism | Daily data verification |
| community residents | Pay attention to official announcements | Stay away from abnormal fumaroles |
| Scientific research institutions | Share monitoring data | Establish unified standards |
As the "double carbon" goal advances, the scale of geothermal development will continue to expand. Correctly understanding the changing laws of geothermal pressure is not only related to energy security, but also an important link in the prevention and control of geological disasters. It is recommended that the public obtain authoritative information through the national geothermal data sharing platform and avoid spreading false rumors.
