摘要
根据实测和收集整理华北地区各区块约2000余个镜质组反射率Ro的分析数据,结合前人研究成果,较为系统地阐述了华北地区上古生界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,初步确定了华北地区二次生烃的分布范围。
Based on more than two thousands vitrinite Ro data of actual measurements and previous research results,the authors systemically discussed the characteristics of thermal evolution and the stage of hydrocarbon generation and evolution,and the formative condition of secondary hydrocarbon generation from Upper Paleozoic coal measures in Northren China area.The distributive range of secondary hydrocarbon generation in Northern China area is also determined.
