【摘要】 多相除砂器体积小、结构紧凑,适用于面积有限、操作空间狭小的海上采油平台。论文借助试验手段对特定结构的样机进行分离性能研究,主要工况为:①入口气液比一定,改变入口总流量;②入口总流量一定,改变气液比。试验结果表明,气液比和入口总流量的改变对粒级效率、总分离效率、d₅₀等性能指标影响较为明显。多相除砂分离器在低流量下总分离效率较低,在高气液比下d₅₀数值较大。因此多相除砂分离器应在高入口流量和低气液比的参数范围内运行。更多还原

【Abstract】 Multiphase desander,with small size and compact structure,is suitable for offshore oil platforms with limited operating space.Separation performance of the prototype desander is studied by means of experimental methods.The test is divided into two parts:changing total flow at the entrance with the entrance gas-liquid ratio fixed,and changing the entrance gas-liquid ratio with total flow at the entrance fixed.Experimental study shows that total entrance flow and gas-liquid ratio influences total separation efficiency,value of d₅₀ and pressure drop significantly.It is found that overall separation efficiency of the separator is lower under lower flow rate,and value of d₅₀ is greater under higher gas-liquid ratio.So the multiphase sand separator should operate on higher entrance flow and lower gas-liquid ratio.更多还原
