摘要： 在国内外气田大量汞检测数据的基础上,结合煤系演化过程中汞含量的变化规律,对天然气中汞的来源和富集条件进行了探讨,认为高含汞气田的形成需要 2 个条件,一是有效的岩浆活动,二是一定的保存温度。因此,我国高含汞气田最有可能出现的地区为东部拉张断陷盆地和西部前陆盆地的深部地层。

Abstract: Based on the great amount of measured data of mercury at home and abroad, integrated with the variation of its concentration in coal measures in the course of evolution, this paper discusses the source and enrichment conditions of mercury in natural gas, and suggests that the formation of a high mercury concentration gas field needs two conditions, one is effective magma activity, the other is special temperature. So the dominant distribution area of high mercury concentration gas could be in the deep strata of the tension fault basin in eastern China and foreland basin in western China.
