Study on structure optimization and performance of downhole gas-liquid hydrocyclone under high gas-liquid ratio
摘要
Abstract
To address challenges in efficient gas-liquid separation under high gas-liquid ratio conditions,a novel cyclone-gravity coupled downhole gas-liquid separator is proposed.Combining experimental research,numerical simulation and experimental design methods,the significance analysis and optimal design of the gas-liquid separator structural parameters were carried out,a mathematical relationship model between the significant structural parameters and the gas-liquid separation efficiency was established.The best matching scheme for structural parameters was established.The combined design of gravity sedimentation and hydrocyclone separation proves effective in achieving liquid phase deposition under high gas-liquid ratios,leading to high-efficiency gas-liquid separation.The results indicate that separation efficiency rises with liquid intake,stabilizing within a range.Within certain working conditions,the gas-liquid ratio initially enhances separation efficiency,then decreases.The optimal liquid intake is 42 m³/d,the optimum inlet pressure is 2 MPa,and the optimal gas-liquid ratio is 700∶1,97%efficiency is achieved under optimal conditions.The simulation and experimental results align well,offering novel insights and references for the research and development of gas-liquid separation equipment.关键词
