Abstract: Fluid flnows in oi1 wells are usually multiphase fluid flows with different region.Thecomplexity of multiphase flows bring a series of problems to production log interpretation,and up to now,no interptetive models have been found to be suitable for it.In this paper,the physical mechanism of downhole flows is analysized based on arifting model,the relation-ship between production log responses and fluid flow parameters is examined with experi-mental data for modelling fluid flows,and a reliable production log interpretative model isproposed.The field tests show that the new model can make much enhancement in the accuracy of production log interpretation for multiphase flows in oil wells.
