天然气能量计量探讨

Exploration of Heating Value Metering of Natural Gas

按质论价是市场经济的公平方式。然而，长期以来天然气贸易计量是按标准状态下体积流量进行结算的，不管天然气组份如何，发热量是高或是低均是相等价格，这是不合理的。由于天然气是从各个油气田不同油气藏采出的，其组份千差万别，发热量各不相同，重组份多的天然气发热量就高，轻组份多的天然气发热量就较低，矿井气、人造煤气发热量就更低。为了克服这种不公平现象，天然气（燃气）进行能量计量是可取的。本文就如何进行天然气能量计量作粗浅的探讨。

For a long time past,the volume flowmetering method has been used for natural gas metering in natural gas trade in despite of component and heating value of natural gas. It is unreasonable.In order to eliminate this unfair matter,heating value metering method should be used for natural gas metering. This poper explores how to carry out the heating value metering for natural gas.
