筛选油气化探方法的最佳组合,可以充分发挥化探的优点,本文综合不同介质中能提取的各类油气信息及各种方法指示油气的可靠程度等因素提出最佳组合系统,讨论了其应用特点和组合关系,并举出实例说明其实用意义.

In view of the limitations of the individual methods used in oil/gas geochemical explorations,the optimization of organization of the various methods would bring the advantages of the geochemical exploration into full play. The main methods of the geochemical exploration and the practices at home and abroad are introduced in this paper. Based on the available informations and the reliabilities of the different oil/gas indicators, it is suggested that the optimum organization of geochemical methods should take the hydro-geochemistry method as the main body,supported by gaseous hydrocarbon method, methane isotopic method, AC method, ultraviolet absorption spectroscopy and fluorescence spectroscopy. Finally,the applications of the above methods and the relationships between them are also discussed with examples.
