摘　　要：湿天然气不分离测量技术的推广和应用对于降低油气田的投资和运行成本,提高油气田的生产效率和科学管理水平都具有重要意义。与传统的分离计量技术相比,湿天然气不分离计量技术可极大的简化天然气井口地面工艺流程,据估算总体可降低10%~30%的井口地面建设成本,在技术经济性和运行管理上都具有显著的优势。随着近年来页岩气和致密气等非常规天然气发开对湿天然气测量技术的需求,近年来湿天然气在线测量技术得到了较大的发展,出现了多种不同测量原理的湿天然气流量计,并开始在油气田生产现场开始了小规模的工业应用。文章对某气田区块应用的40余套湿天然气流量计进行了数据统计,研究分析了现有湿天然气流量计在现场的应用情况,为油气田湿天然气测量方案的优化和测量技术的发展提供参考。The popularization and application of wet gas non-separation measurement technology is of great significance to reduce the investment and operation cost of oil and gas fields,improve the production efficiency and scientific management level of oil and gas fields.Compared with the traditional separation metering technology,the wet gas non-separation metering technology can greatly simplify the natural gas wellhead process,and it is estimated that the overall wellhead construction cost can be reduced by 10%to 30%,which has significant advantages in technical economy and operation management.With the development of unconventional natural gas such as shale gas and tight gas in recent years,the demand for wet gas measurement technology has been greatly developed in recent years.A variety of wet gas flowmeters with different measurement principles have appeared,and small-scale industrial applications have begun in oil and gas field production site.In this paper,more than 40 sets of wet gas flowmeters used in a gas field block are statistically analyzed,and the application of existing wet gas flowmeters in the field is studied,which provides a reference for the optimization of wet gas measurement scheme and the development of measurement technology.
