Distributed optical fiber temperature sensor and its application in high-temperature well logging

This paper analyzes the demand of temperature measurement for high temperature wells of oilfields and demonstrates the unique advantages of the distributed optical fiber temperature sensors in comparison with conventional means for temperature measurement. Through the actual test results of the heavy oil area, the feasibility and advantages of the distributed optical fiber temperature measurement are verified. A summary of development trend of the distributed optical fiber temperature measurement system as the core technology applied in the oilfield logging is also given.
