渤海湾盆地C-P煤有机组分^(13)C NMR研究

Research on 13 C NMR of Major Macerals of Coals in Bohaiwan Basin

渤海湾盆地是我国东部地区重要的油气基地，这里广泛的分布着石炭—二叠纪煤系地层．通过对煤中主要有机组分——角质体和基质镜质体的固体１３Ｃ核磁共振（简称１３ＣＮＭＲ）研究，揭示了它们的化学组成与结构特征，论述了它们对该区油气生成的意义，并从定量分析的角度，评价了研究区石炭—二叠纪煤中不同有机组分对油气生成的贡献．

Bohaiwan Basin is an important petroleum area in east China.The coal bearing series of Permo Carboniferous in the basin distributes extensively. The characteristics of solid 13 C neuclear magnetic resonance ( 13 C NMR) of the major maceral(cutinite and desmocollinite B) are discussed.The chemical composition and structure is revealed, and the oil generating significance is demonstrated. The contribution of different coal components of C P coals in the studied region to oil gas generating are evaluated through quantitative analysis.
