我国油气地球化学分析技术自20世纪50～60年代从前苏联引进以来,经历了奠基建立、壮大发展、提高创新3个发展历程。近年形成的比较突出的新技术新方法主要是:油、气、岩轻烃测试技术方法;天然气有机地球化学以及运移、封盖条件测试技术方法;有机岩石学测试技术方法;油藏地球化学分析技术方法与二次生烃热模拟实验技术方法等。油气地球化学实验测试技术今后的发展趋势是:重视和发展快速定量分析技术及计算机和多机联机分析技术;研究和建立油气水运移地球化学分析技术和聚集评价技术;建立我国南方碳酸盐岩评价实验分析技术及标准;进一步加强完善天然气资源评价及运移、聚集和保存条件等方面的分析技术研究。

The oil and gas geochemical analysis technology has gone through three processes of establishment,growing and innovation in our country since it being introduced from former Soviet Union in 1950's.The important new techniques developed in recent years are detection of light hydrocarbons in oil,gas and rock,organic geochemical methods determining the migration and covering conditions of natural gas,organo-petrologic analysis methods,reservoir geochemical analysis techniques,thermal simulating experiment technique of quadratic hydrocarbon-generation and so on.The development trends of oil and gas geochemical analysis technology mainly include paying great attention to high-speed quantitative analysis and multi-instrument on-line detection techniques,developing the geochemical analysis methods of oil-gas-water migration and accumulation,establishing the experimental analysis methods and standards on carbonate rock evaluation in the south of our country and further perfecting the analysis techniques on natural gas migration-accumulation-preservation conditions and natural gas resource evaluation.
