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。

Abstract: This paper presents the principle and basic equations for orifice metering, as well as convertible characteristic of steam and water phases by steam stimulation process. The corrected coefficient K is introduced 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 differential equation. The errors in field application is less than 10% that could meet the real requirement of heavy oil production.

Key words: heavy oil, steam stimulation, choke, pressure differential
