【摘要】 一直以来同位素地球化学在气源对比研究中发挥着重要作用,天然气组分碳、氢稳定同位素已经用于判别天然气的烃源岩、源岩热演化程度和成藏过程,稀有气体同位素也已经广泛运用于天然气的来源判别。近年来,又发展了诸如流体包裹体气源对比方法,利用苯、甲苯、二甲苯、甲基环己烷等轻烃单体碳同位素气源对比方法,天然气组分的详细解剖与气源直接对比方法和气源动态综合对比方法等,这些方法促进了天然气气源对比的深入研究。比较系统地介绍了气源对比方法上的发展、创新和今后发展的一些趋势。更多还原

【Abstract】 Source rock correlation research has important practical and theoretical significance in the field of oil and gas exploration and development.Isotope geochemistry has been playing an important role in the gas and source rock correlation.Component carbon,hydrogen stable isotope of natural gas can identify source rock,thermal evolution of source rock,and accumulation process of natural gas.Noble gas isotope has been widely used to identify sources of natural gas.In recent years,some other methods are developed such as the method using fluid inclusions,benzene,toluene,xylene,methyl cyclohexane and other light hydrocarbons to study gas and source rock correlation,the direct contrast of gas source to the detailed anatomy of gas components,and the dynamic comprehensive comparison method.This paper introduces the development and innovation of gas and source rock correlation and its development trend in the future.更多还原
