Abstract

Abstract: The separation efficiency of gas anchor is a very important index to evaluate the performance of gas anchor.Because it works in high temperature and high pressure environment,no apparatus can measure its separation efficiency.In order to study the influence of flow parameter on gas anchor separation efficiency quantitatively,a gas anchor and related experiment apparatus are designed and two important parameters,flow velocity and gas oil ratio,that influence separation efficiency studied.The experimental results show separation efficiency increases with gasliquid ratio,when gasliquid ratio is greater than 0.75,the influence of gasliquid ratio is not so important.The separation efficiency increases with flow velocity,when flow velocity is low,the different separation efficiency caused by gasliquid ratio is distinct.When flow velocity increases,the trend of difference reduces.At last，theoretical method is used to verify the result of experiment.This research can give some insight on gas anchor quantitative separation efficiency analysis.

Key words: gas anchor, gas separation efficiency, experiment, flow velocity, gas liquid ratio
