应用煤岩学分析鸡西盆地煤成气前景

鸡西盆地是一个多煤层、多煤种的中、新生代聚煤盆地,丰富的煤炭资源为煤成气的形成提供了充足的物质基础。不但生产矿井具有明显的矿井瓦斯显示,而且在以往的地质勘探过程中曾发现过喷气钻孔,经研究这是煤成气的直接显示。本文主要应用煤岩学的基本理论和方法,通过分析各种煤岩组分的生烃能力以及鸡西盆地的显微组分分析,并结合其它方面的研究,来阐述鸡西盆地的煤成气前景。

Using Coal Peotrology Analysis Potentiality of Coal-Formed Gas in Jixi Basin

There are many coal beds and various coal ranksni Jixi basin, which is a Mesozoic and cenozoic coal basin. The abundant coal resource gave out a rich basis of the coal-formed gas formation. Not only the methane appeared in the mining mines, but also the gas spraying well(87-20)was discovered in the past gcologic exploration. By research, it is the direct appearance of coal-formed gas. By using the methodand theory, of coal peotrdogy, analysing the macerals and their ability to generate hydrocarbon and other as pecl nesearch, in this paper the authors discussed the poteintialities of coal-formed gas in Jixi basin.
