| 摘 要： | 通过对我国不同时代，不同产地煤层中菌藻生物化石的种类和丰度研究，观察到煤层中的菌藻类生物具形态各异，属种繁多，数量丰富的特征。经热模拟实验证明：菌藻类煤的成烃能力比同煤级的腐植煤高，（甲烷高1－2倍，液态烃高4－5倍），尤其对深水区形成的腐泥煤，是石油的主要母质。因此，今后在寻找煤层气或煤成油的有利区块时，应深入的研究成煤环境和成煤物质。

| Abstract: | The kinds and abundance of thallophyta fossils in coal from different places and different ages in China are studied with microscopic examination.It is observed that thallophyta in coals were characterized by different kinds of morphological feature,rich of genera and abundance.The results of thermal modeling suggested that the hydrocarbon generated capacity of sclerotia algal coal is higher than humus coal.Especially the sapropelic coal generated in deep water area is the important base material of oil.Therefore,the study of coal generation environment and coal generation material must be important for identifying payable area in future. |
