华北地区上古生代煤系有机质热演化与二次生烃探讨

Discussion on thermal evolution and secondary hydrocarbon generation of organic matter from Upper Paleozoic coal measures in Huabei area

根据实测和收集整理华北地区各区块约 2 0 0 0余个镜质组反射率R的分析数据 ,结合前人研究成果 ,本文较为系统地阐述了华北地区上古生代煤系有机质的热演化特征与成烃演化阶段性 ,探讨了其二次生烃条件 ,并初步确定了华北地区二次生烃的分布范围。

Based on over two thousands of vitrinite reflectance(R)data from actual measurements and previous research results,it is systematically discussed that the characteristics of thermal evolution,stages of hydrocarbon generation and evolution,as well as the conditions of secondary hydrocarbon generation in Upper Paleozoic coal measures in Huabei area.The distribution range of secondary hydrocarbon generation in Huabei area is also determined.
