中文摘要：

在地质研究当中,扫描电镜作为一种新的技术手段越来越受到人们的重视.烃源岩作为油气成藏的先导因素,其重要性不言而喻,研究烃源岩也成为了各大油田和地质研究所的重中之重,因此其研究方法众多.而运用扫描电镜对其微孔隙、干酪根以及煤层气进行研究,具有特别的优势.扫描电镜能够从微观上了解烃源岩的岩石矿物、古生物以及某些地球化学标志,从而对烃源岩生油能力作出评价.对于干酪根和煤层气,扫描电镜可以详细观察从岩石中分离出来的干酪根以及岩石表面的气孔、油膜,对该烃源岩进行准确评价,为以后的油田开发提供有利的指导.

英文摘要：

In geological research, the scanning electron microscopy （SEM） has been paid more and more attention as a new technique. As the leading factor of hydrocarbon accumulation, the importance of source rock is self-evident. Research on the source rock has become the top pri- ority of major oilfields and geological research institutes, so its research methods are numerous. SEM is used to study its micro pores, kerogen and coalbed methane, and this method has a special advantage. By using SEM, the rock minerals, paleontology and some geochemical marks of source rock can be understood microscopically, thus the source ability of source rock will be evaluated. For kerogen and coalbed methane, SEM can be used to observe the kerogen, pores and oil film on the rock surface, and an accurate assessment will be made for the source rock. All of above will provide a favorable guidance for the futural development of oilfields.
