| 摘 要： | 天然沥青反射率(ROB)作为碳酸盐地层成熟度指标的可靠性是一直在探索而又未完全解决的重要问题。研究表明,各种成因类型的沥青具有不同的光性演化特征与规律,具有特征的分子结构与化学组成,必须建立各自特有的ROB与镜质体反射率(RO)关系式,并应利用不同沥青类型的特征结构与组成对其进行成因分类。此外,采用气相色谱/红外光谱联用技术(GC/FTIR)及高效液相色谱(HPLC)等对沥青中的芳烃馏份及沥青质的演化特征进行了初步研究。这些化合物的研究严重滞后,但确实蕴藏着丰富的演化信息。

| Abstract: | The reliability of natural bitumen reflectance (ROB) as a maturity index of carbonate strata is always a controversial issue which has not been settled completely.It is revealed in studies that bitumen of different genetic type possesses different optical evolutionary characteristics and rules and has characteristic molecular structural and chemical composition.Therefore,special relational equations between ROB and vitrinite reflectance (RO) must be set up respectively for different bitumen,and the geneses of bitumen be classified according to the characteristic structure and composition of different bitumen types.Besides,the evolutionary characteristics of aromatic fraction and asphaltene in bitumen are studied preliminary by means of Gas Chromatography/ Fourier Transform Infrared Spectroscopy (GC/FTIR) and High-performance Liquid Chromatography (HPLC) There are indeed a wealth of evolutionary information in these compounds.But the studies on them is seriously behindhand. |
