Abstract

In view of the void fraction measurement problem of oil-gas-water three phase flow in oil production logging, in this thesis, optical fiber probe sensor is used to measure the cross-sectional local void fraction. In order to analysis post-treatment raw probe signal preferably and more reasonable, firstly, the characteristic of optical fiber probe pierced bubble is analyzed and simulated by the simulation modeling with ZEMAX, and adopting non-sequential ray tracing method to simulate the track characteristic of the light energy variation in the sensing system, which both from the different horizontal radial positions of probe pierced bubble and different axial positions of the probe; Then, in order to get the accurate local void fraction information, gas-phase distribution features in fluid pipeline and flow regime identification of multiphase flow, the transformation of binary value signal in probe signal post-processing is analyzed and compared by different threshold methods. Finally, the experimental platform of void fraction measurement is built to obtain the probe raw signal of oil-gas-water three-phase which total flow is 30m3/d, and the effects of different threshold method are confirmed.
