已查明石油中有大量的镍、钒、汞、钴、铜、锌、钼和许多其他化学元素,它们或集中在石油的重沥青——胶脂成份内,或者集中在轻烃馏分中。以流动形式存在的化学元素渗入围岩中,扩散到地表和邻近的大气层中,上述晕的记录可以揭露含油气目标。为了寻找油气田,主要利用可以直接指出烃源的烃气晕。但是,不仅油气田,而且遭受过还原作用的地表有机质建造、某些深部减压的目的层等都可能是这样的烃源,这迫使我们寻找一些探明油气田,特别是埋藏在极深部油气田的新方法,重金属晕的利用可能是测定烃气晕源的辅助指标。除此以外,在许多情况下重金属晕本身的特殊性质可
It has been ascertained that there is a significant amount of nickel, vanadium, mercury, cobalt, copper, zinc, molybdenum and many other chemical elements in petroleum, either in heavy petroleum-based greases or in light hydrocarbon fractions. Chemical elements in the form of flow seep into the surrounding rock and diffuse into the Earth’s surface and the adjacent atmosphere. The above recorded halo can reveal hydrocarbon-bearing targets. In order to search for oil and gas fields, hydrocarbon haloes, which directly point out hydrocarbon sources, are mainly used. However, not only oil and gas fields, but also the surface organic matter undergoing reduction and the formation of some deep decompression target layers may be such hydrocarbon sources, which forced us to search for some proved oil and gas fields, especially those buried in very deep oil and gas fields The new method, heavy metal halo utilization may be an auxiliary indicator of hydrocarbon gas halo source. In addition, in many cases, the special nature of heavy metals can itself
