吐哈盆地煤岩特征与分布

COAL FEATURE AND DISTRIBUTION IN TUHA BASIN

吐哈盆地内不仅蕴藏着丰富的石油天然气及煤炭资源,而且蕴藏着丰富的煤层气资源。主要是从吐哈盆地煤岩特征入手,展开对煤质、煤岩组分、煤演化程度、煤层分布、厚度、埋深、生烃特点的分析研究。通过利用大量的井资料和实验数据分析这些因素对煤层气生成及产出的影响,为在吐哈盆地寻找煤层气勘探有利区带提供重要依据。

There are not only abundant oil and coal but also rich coalbed gas in Tuha basin. The coal composition, coal evolution rank, coalbed distribution, thickness, burial depth and hydrocarbon generation feature were analyzed from coal feature in Tuha basin. The effect of these factors on the generation of coalbed gas was analyzed by well data and experiments, which laid a concrete foundation for the exploration of coalbed gas in Tuha basin.
