| 摘 要： | 无机组分虽然不是油气的基本组分,但它们种类繁多,与油气烃类的生成运移有着不可分割的联系。因此针对与油气田伴生的微量元素进行分析研究并寻找油气是一种有效的地球化学勘查方法。通过研究发现:油气评价的有效微量元素指标主要为Hg和w(V)/w(Ni)、w(V)/w(Fe),其次为w(N)/w(Org.C)、Pb、U;微量元素油气化探异常模式为环状,即油气藏上方为低值区,油气藏边缘为高值异常区。 |
| 关 键 词： | 地球化学勘查 微量元素 油气藏 |

| Abstract: | Inorganic components, though not the basic components of oil and gas, are very intimately connected with the formation and migration of oil-gas hydrocarbon. Hence the analysis and study of associated elements in the oil and gas field make up an effective geochemical method in search for oil and gas. Studies show that the effective trace element indices in oil and gas evaluation are mainly Hg, V/Ni, V/Fe and subordinately N/Org.C, Pb and U. Trace element anomalies for oil and gas geochemical exploration are in the ring form, with the low value area over the oil and gas accumulation and the high value anomalous area on the edge of the oil and gas accumulation. |
| Keywords: | geochemical exploration trace elements oil and gas accumulation |
