The distributed fiber optic temperature monitoring system (DFA) of Guoxing Huijin utilizes the Raman backscattering principle and optical time-domain reflection technology, embedded in the core algorithm of rock fluid thermal dynamics calculations to accurately obtain the formation temperature profile in real-time and quickly analyze the temperature profile of the well. The system is paired with special optical cables and data analysis software to form the DFA system which is mainly used to obtain a quantitative and qualitative analysis of the production and injection profile of a well. The DFA system incorporates the latest generation of high-speed data acquisition components and real-time monitoring algorithms based on FPGA and ARM integration. The design strengthens the temperature signal and feedback capabilities, thus improves the quality of the interpretation. This series of products has built-in intelligent functions such as temperature self calibration, remote control, and industry standard data transmission options.
