摘要
吸附态轻烃是沉积岩层中轻烃的主要赋存状态之一，主要来源于油气藏轻烃源，其吸附的物理化学状态及组成和含量上的特征代表着极其丰富和重要的地球化学信息，采用不同的方法和手段使沉积岩样品中的吸附态轻烃解吸出来，然后分析其组成和含量，就可以从不同的角度来了解和认识样品所对应层位及下伏地层的含油气信息。
Being one of the major modes of occurrence of light hydrocarbon in sedimentary strata,the adsorbed light hydrocarbon is mainly derived from light hydrocarbon source of oil and gas accumulation.Its adsorption physicochemical state,composition and content characteristics embrace exttremely abundant and important geochemical information.With different means, the adsorbed light hydrocarbon can be absorbed from samples of sedimentary rocks and then be analysed for its composition and content.In this way,one might understand the oil and gas information of the horizon represented by the samples and the underlying strata from different angles.
