AN ENRICHMENT TECHNIQUE OF FREE HYDROCARBONS AND ITS APPLICATION IN PETROLEUM GEOCHEMICAL EXPLORATION
-
摘要: 作者根据热力学和动力学的原理,自行设计和研制了游离烃类气体的浓缩富集装置.该装置可将空气中的游离烃类的浓度提高若干个数级,无疑为油气化探痕量烃类样品的分析开避了前景.它不仅解决了油气藏上方地表气层的空气和土壤中空气样品痕量烃类(C1~C7)的分析,同时还可应用于罐顶气、水溶气的分析和海域油气化探.Abstract: Based on the principles of thermodynamics and dynamics,the authors designed and developed a new device for the concentration and enrichment of hydrocarbon gases.So that it can increase the concentration of free hydrocarbons in the air by several orders of magnitude,which certainly opens up the way to further the analysis of trace hydrocarbon in petroleum geochemical exploration.It can not only improve the analysis of trace hydrocar-bon(C1-C7)in air samples from the surface gas bearing beds and the soil above the oil/ gas pools,but also be applied to analysing the tank-top gas and water-soluble gas as well as to petroleum chemical exploration in marine area.
