Abstract:

Mercury in natural gas is harmful to the oil and gas processing equipments and natural environment. The statistic data of mercury content in natural gas worldwide show that mercury abundance depends upon their hosting rocks, is higher in coal than that in oil. In some oilgas basins, mercury abundance is high thanks to deep faults, magma and deep geological progresses. It has two origins, organic and inorganic, which define mercury content in natural gas.

Key words: natural gas, mercury, content, origin mechanism

摘要:

天然气中含汞十分普遍,部分天然气藏汞含量较高、变化范围大。天然气中汞的赋存对油气加工及自然环境有较大的危害。对国内外天然气中汞含量的数据统计显示,源岩母质类型决定汞含量,煤型气中汞含量普遍高于油型气汞含量;而部分含油气盆地油型气汞含量较高,这主要与深大断裂的发育、岩浆活动和深部地质过程有关。天然气中汞的成因分为有机和无机两种成因,并且不同的成因机制决定天然气中汞含量的差异。
