摘要
为定量研究流动参数对气锚分气效率的影响,设计加工了实验用的气锚和相应的配套装置,对流动速度和气液比这两个影响气锚分气效率的重要因素及流体在气锚中的流动特点进行了研究。实验结果表明:随气液比的增大,分气效率增大,但当气液比大于0.75时,分气效率受气液比影响不再明显;分气效率随流速的增大而增大,当流速较小时,由气液比的不同引起的分气效率的差别比较大,而随着流量的增大,这种差别呈逐渐缩小的趋势。理论计算与实验结果比较,验证了实验结果的正确性,对气锚分气效率的定量分析具有借鉴意义。
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.
