摘　　要：研究聚焦数字油田背景下井口气液分离与气量测量技术,通过建立Sulzer Knit MeshTM气液分离装置的物理和数学模型,深入探讨了气液比和分流比对分离效率的影响机理。结果表明,最佳工作气液比为15~25,最佳分流比范围对应的筒体直径与进口直径比值为6~10。在优化参数范围内,分离器出口含气率可低至0.02%~0.06%,含液率维持在35×10^(-6)~80×10^(-6),分离效率达到93.8%~97.6%,为数字化油田建设提供有力参考。This study focuses on the technology of wellbore gas-liquid separation and gas volume measurement in the context of digital oil fields,and establishes the physical and mathematical models of Sulzer KnitMeshTM gas-liquid separation device,and thoroughly explores to investigate the influence mechanism of gas-liquid ratio and split ratio on separation efficiency.The results indicate that the optimal working gas-liquid ratio is 15~25,and the ratio of cylinder diameter to inlet diameter corresponding to the optimal split ratio range is 6~10.Within the optimized parameter range,the gas content at the outlet of the separator can be as low as 0.02%to 0.06%,the liquid content can be maintained at 35×10^(-6) to 80×10^(-6),and the separation efficiency can reach 93.8%to 97.6%,providing strong reference for digital oilfield construction.
