摘要:
针对塔河油田现有掺稀降黏工艺中稀油与稠油由同一吸入口进入,两者互相干扰致使掺混不均从而堵塞油管的问题,设计了一种将稀油吸入口与稠油吸入口分开的分流式掺稀混配器。借鉴前人的混配效果评价方法,利用数值模拟方法分析了分流式掺稀混配器稀油吸入口直径、孔眼层数、开孔角度对混配效果的影响,根据模拟结果优化了分流式掺稀混配器的结构参数,最佳结构参数为稀油吸入口直径8.0 mm,沿轴向4层排布,开孔角度33°。分流式掺稀混配器的性能室内试验结果发现,稀油和稠油经过分流式掺稀混配器后,其混合均匀程度较高。研究结果表明,分流式掺稀混配器可以提高稀油与稠油的混合均匀程度,解决了因稀油和稠油掺混不均而堵塞油管的问题。
Abstract:
The existing oil viscosity reducing technique used in Tahe Oilfield takes thin oil and heavy oil through one inlet where both states interfere with each other.The interference may result in uneven mixing and lead to tubing blocking.In view of the above-mentioned problem,a kind of shunting dilute mixer that separates a thin oil suction inlet from a heavy oil suction inlet was designed.By referring to previous evaluation method of the mixing effect,a numerical simulation method was used to analyze influence of the pore aperture,the tapping layers and the tapping angle of the thin oil suction inlet on the mixing effect.Based on simulation results,the structural parameters of the shunting dilute mixer were optimized to the setting of 8.0 mm optimum aperture of thin oil suction inlet,arranged in 4 layers along the axial direction,with a tapping angle of 33°.The lab test results on the performance of the designed shunting dilute mixer showed that it had a high mixing uniformity after thin oil and heavy oil passed through the shunting dilute mixer.Therefore,the shunting dilute mixer could improve the mixing uniformity of thin oil and heavy oil,and solve the problem of tubing blocking caused by the non-uniform mixing of thin oil and heavy oil.
