摘要
利用有机地化方法解决宁夏灵武煤田延安组煤层对比的研究表明:区内2、6、7、14、17煤的某些有机地化参数,如氯仿沥青“A”含量、氢指数、产烃潜量、正烷烃碳数分布和烷基菲构成均存在明显差异,这取决于煤层沉积环境、煤化作用程度和有机母质类型。有可能依据这些参数,使煤层本身成为对比的标志层。
The study of the coal correlation in Yenan Formation (Ningsia Region) reveals that there are obvious differences among several main coal beds as 2,6,7,14,17 of the research area, in the characteristics of some organic geochemical parameters such as, 'A'％, I_(H), potential hydrocarbon, the distribution of n—alkanes and the consitution of alkylphenanthrenes. It seem to depend on the condition of oxidization—reduction;the degree of coalification and the type of raw organic matter. It is possible to make coal beds themselves become correlation mark ones.
