摘　　要：根据孔板计量的原理和基本方程,针对蒸汽—水两相的可转化特性,引入了校正系数K,通过单炉对单井方式注汽试验求取了K值,进而用油嘴-压差公式求出了不同油嘴、温度、压力和压差下的蒸汽流量。现场应用误差小于10%,基本满足了实际生产的需要。This paper presents the principle and basic equations for orifice metering,as well as convert-ible characteristic of steam and water phases by steam stimulation process.The corrected coefficient K is in-troduced and calculated in the manner of single steam generator to single well,by which the steam flow rates in different chokes,temperatures,pressures and pressure differentials are gained using choke-pressure differen-tial equation.The errors in field application is less than10%that could meet the real requirement of heavy oil production.
