| 摘 要： | 利用浅表土壤气中的Ｈｅ组分及Ａｒ同位素进行油气田地球化学勘探，发现Ｈｅ不仅是油气藏的原始指示剂，而且是油气田通导的反映；Ａｒ从气藏向地表迁移过程能发生同位素分馏，这吓分馏不仅对确定油气田的异常有重要意义，而且还反映了油气藏盖层的渗漏能力的大小。Ａｒ是Ｈｅ，Ａｒ，烃三参数的扭带，以以此建立了八种Ｈｅ，Ａｒ，烃组合模型，提高了对油气藏的地球化学勘探的评价能力。

| Abstract: | The changes of helium in soil gases to are used in geochemical oil-gas exploration Caoqiao, Quangrao County, Shendong Province.
As associated compositions in oil-gas pool, argon and helium have the significance as primitive indicator. Their migration is only a physical process not subjected to any chemical changes, so argon is an ideal indicator as helium.
Argon isotope in soil is significant for locating the oil gas pool, but also can reflect the ability of leakage of the covering strata. Eight patterns are established for helium, argon and hydrocarbon, which can complement and verify each other, and enhance the ability of synthetical appraisal. |
