Advantages of વિતરિત ફાઇબર ઓપ્ટિક તાપમાન માપન સિસ્ટમ for geothermal wells:
1. Long distance underground geothermal temperature measurement
The underground distance is generally quite long, ranging from several hundred meters to several thousand meters, and even longer distances. Distributed fiber optic temperature measurement systems can be applied to long-distance temperature measurement. The system conducts real-time temperature inspections of the entire tunnel area, monitors the on-site environmental temperature inside the tunnel, covers 100% of the tunnel area, and has no measurement blind spots.
The system has multi-level positioning reporting, differential temperature reporting, and forecasting functions. Once the temperature value or temperature rise rate of the tunnel environment exceeds the set threshold, it automatically sends out sound and light alarm information and transmits it to the fire host.
When a fire occurs, provide timely information and accurately locate the location of the fire, and can be linked and controlled with other fire-fighting facilities through relay output modules.
Real time temperature information and data can be automatically maintained, with historical data viewing and statistical analysis functions.
The system has a self diagnostic function, and if it detects damage to the optical cable, the system can promptly locate the fault point.
2. Real time monitoring of underground geothermal temperature
The geothermal underground distributed fiber optic temperature measurement system can display the downhole temperature of the oil well in real time, detect abnormal situations in a timely manner. વધુમાં, by analyzing long-term temperature data, the stratification of downhole temperature can be obtained to guide production. Real time online temperature monitoring;
Provide early detection of underground temperature anomalies;
Clearly indicate the location of abnormal temperature;
Software analysis of historical single point temperature data at any point underground;
People gradually realize the importance of coordinated development between resource extraction and environmental protection, and the utilization of clean and renewable energy has been given attention. Geothermal energy is extracted as a clean and efficient energy source. Through drilling technology, a wellbore several hundred to several thousand meters deep is drilled below the formation to extract geothermal water, which can be used for industrial power generation or domestic hot water. Geothermal energy is mainly divided into three categories: high temperature, medium temperature, and low temperature. સામાન્ય રીતે, geothermal energy with a formation temperature above 150 ℃ is considered high temperature geothermal energy, while geothermal energy with a temperature between 90 ℃ and 150 ℃ is considered medium temperature geothermal energy. Geothermal energy with a temperature below 90 ℃ is considered low temperature geothermal energy. High temperature geothermal energy is generally used for industrial power generation, while geothermal energy with a temperature below 90 ℃ mainly provides hot water services.
In order to grasp the drilling status and geothermal well development effect, it is necessary to timely obtain the temperature distribution of the geothermal well formation. The temperature measurement system of geothermal wells obtains the temperature situation of the wellbore of geothermal wells.
The distributed fiber optic temperature monitoring system for geothermal deep well walls includes a distributed fiber optic temperature testing device, a high-temperature resistant armored optical cable, and an optical cable crossing device; The distributed fiber optic temperature testing device is connected to the high-temperature resistant armored optical cable;
Distributed fiber optic temperature testing device, used to send laser signals to high-temperature armored optical cables, receive Raman scattering light signals carrying temperature information returned by high-temperature armored optical cables, and analyze and display them;
High temperature resistant armored optical cable, passing through the cable crossing device, geothermal deep well, and transmitting laser signals, collects temperature information at different wellbore positions in the geothermal deep well, and returns the temperature information as Raman scattering light signal to the distributed fiber optic temperature testing device;
Optical cable crossing device, installed at the wellhead, is used for crossing high-temperature armored optical cables and sealing casing cementing cement.
