摘　　要：针对海上油田低含气率采出液除气作业需求,本文提出了一种被动式轴向旋流除气装置。据此设计了原理样机,接入自循环流动系统中开展了除气特性测试工作。重点考察内部流场气相分布,考察分流比、除气率、处理后液体含气率和压降之间的关系。研究表明,通过合理调整分流比,该装置可将液体含气率降低至0.1%。同时,入口-溢流口相对压降与分流比之间存在线性关系。研究成果有利于进一步降低管式分离系统的空间和重量需求。In consideration of degassing demands of produced fluids with relatively low gas content in offshore oil production,this work proposed a passive axial swirling degassing device.Based on this,the principle prototype was designed,and the degassing characteristic test was carried out in the self-circulating flow system.The test focused on the gas phase distribution inside the equipment,and it investigated the relationship among the split ratio,degassing ratio,gas content of the liquid after treatment,and the pressure drop.Studies have shown that by adjusting the split ratio reasonably,this device can reduce the liquid gas content to 0.1%.At the same time,there is a linear relationship between the inlet-overflow port relative pressure drop and the split ratio.The research results help to further reduce the space and weight demand of the tubular separation system.
