摘　　要：针对半潜式油气生产平台闪蒸气压缩机组关键参数测量难的问题,提出一种基于虚拟计量的关键参数实时监测方法。对闪蒸气压缩机组的工艺原理进行深入分析,建立压缩机排气量、洗涤器排液量、后冷器换热效率指数三个关键参数的机理方程组,结合实际工业需求建立相应的虚拟计量模型,在此基础上开发基于虚拟计量的关键参数在线监测系统。在实际工业数据上的应用测试结果表明,所建立的模型能够有效地描述压缩机排气量、洗涤器排液量和后冷器换热效率的变化趋势,解决了关键参数虚拟计量问题。To address the issues of difficulty in measuring key parameters of flash gas compressor units on semi-submersible oil and gas production platforms,a real-time monitoring method for key parameters based on virtual metering was proposed.An in-depth analysis of the process principles of the flash gas compressor units was conducted,and a set of mechanistic equations for three key parameters,including compressor exhaust volume,scrubber liquid discharge volume,and post-cooler heat exchange efficiency index,were established.Corresponding virtual metering models were further developed by combining actual industrial requirements,and on this basis an online monitoring system for key parameters based on virtual metering was designed.Application test results on actual industrial data demonstrated that the developed mechanism models can effectively describe the trends of compressor exhaust volume,scrubber liquid discharge volume,and post-cooler heat exchange efficiency index,and solve the virtual metering problem of key parameters.
