In the immense and vast global biosphere, there exists a kind of noteless melanocratic organic matter which is humic substances.

在浩瀚广袤的地球生物圈里，蕴藏着一种不引人注目的暗色有机物，这就是腐植酸类物质。

Analysis on the content of organic matter indicates that they are equivalent to organic matter of the sapropelic-humic type in the Mesozoic and Cenozoic source rocks in China.

通过有机物组分含量分析，它们相当于中国中、新生代油源岩有机质类型中的腐泥型—腐殖腐泥型。

Therefore, the mechanism that humic-type organic matter can generate gas on a large scale in low-maturity phase can be used to reasonably explain the genesis of the gas in this field.

因此，可以用腐殖型有机质在低演化阶段能规模性成气的机理合理解释该气田的成因。
