Abstract：In order to solve the problem of multi-phase detection in oil production, a new type of dual-receiving fiber sensor (NDR-FOP) for multi-phase detection was developed. A model of dual-receiver ring coupling optical path (DR-RCOP) was constructed using the ZEMAX ray tracing method. The mathematical description and simulation analysis of the light transmission trajectory through the NDR-FOP cone-shaped sensor were carried out. The performance of NDR-FOP multi-phase detection in oil-gas-water multi-phase flow mixed-phase media was also evaluated based on the above research results and it was test on an experimental platform. Simulation and experiment results show that the difference eigenvalues between oil, gas and water media form a clear distance, which proves that the NDR-FOP multi-phase detection is feasible and effective.
