Structural Aspects of the Coalification of Organic Materials

摘要

Coal beds and coal sheets in oil fields consist of coalified material, with similarities and differences due to the conditions in which it was formed. Coal petrography is widely used to assess the properties of coal, and IR spectroscopy is being actively introduced. In tests, the vitrinite reflection coefficient and maceral composition are measured by microscopy and IR spectroscopy for core samples of coal and kerogens. Comparison of the results shows that IR spectroscopy may be used to study the genetic properties of kerogens.
