Research of Steam Quality Prediction Method Based on Venturi Tube

Steam quality used in oilfield thermal recovery cannot be directly measured,but its accurate measurement is directly related to oilfield production and economic benefits.In this paper,on the basis of the homogeneous flow model,considering the influence of the slip ratio on steam quality,and making use of two phase flow measurement principle of Venturi tube,the forecast model of the steam quality was established.Experimental results show that the model can predict the steam quality by Venturi tube,and the error is less than 8%,which can meet the engineering accuracy requirements.
