摘要/Abstract

摘要： The performance of a Venturi tube used in wet gas flow have been explored mainly under higher-pressure condition,but very often,low-pressure test exists in some oil and gas fields in Tianjin Dagang Oil and Gas Field in China.In this study,the performance of horizontally mounted Venturi meters in low-pressure wet gas flow is discussed.Three 50 mm Venturi meters were tested systematically,withβvalues of 0.4048,0.55 and 0.70,the operation pressure of 0.15 MPa,0.20 MPa,0.25 MPa,the gas densiometric Froude number from 0.6 to 2.0,the modified Lockhart-Maretinelli parameter from 0.0022 to 0.06,and the ratio of the gas liquid mass flow rate from 0.5 to 0.99. The effects of modified Lockhart-Maretinelli parameter,pressure,gas densiometric Froude number,diameter ratio, and gas-liquid mass flow rate ratio to the Venturi tube are analyzed with new independent data.Furthermore, low-pressure performance was compared with that under high pressure.
