Abstract

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
