摘要
综述了国内外油气藏定年技术的主要原理和方法,并对各种方法的优缺点进行评述。认为油气成藏年代学的研究已由过去的定性、半定量发展到今天的定量同位素测年的新阶段,其中,在负热电离质谱仪以及多接收器电感耦合等离子质谱仪上,开展原油以及与油气成藏相关的沥青、干酪根等的Re-Os同位素测试工作,可以对油气藏直接定年,并给出精确的油气成藏时间。此项技术具有广泛的应用前景。
The basic principles and methods for dating of hydrocarbon accumulation at home and abroad as well as their advantages and disadvantages are reviewed in this paper. It is suggested that the qualitative, semi-quantitative dating of hydrocarbon accumulation in the past has been developed into quantitative radiometric dating of it nowadays. By using negative thermal ionization mass spectrometry （N- TIMS） and the multi-collector inductively coupled plasma mass spectrometer （MC-ICP-MS）, the Re-Os isotopic dating on materials such as crude oil, bitumen and kerogen that are related to hydrocarbon accumulation can be conducted, directly making dating and giving accurate time of hydrocarbon accumulation. It is of widely prospect for application.
