近几十年来,有关烃微渗漏发生的机制、性质和意义及其与油气藏的关系,一直存在着争议,因此,地球化学勘探未能成为油气勘探的主要手段。从国内外近年来的油气勘探的实践来看,传统的地球化学和地植物探测油气微渗漏的方法,如与遥感结合起来常可获得成功。因为烃与岩石、土壤和植被作用后产生的特殊蚀变, In recent decades, there has been controversy over the mechanism, nature and significance of hydrocarbon microleakage and its relationship with oil and gas reservoirs. Therefore, geochemical exploration has not become the main means of oil and gas exploration. According to the practice of oil and gas exploration both at home and abroad in recent years, the traditional geochemical and geophytic methods for detecting micro-leakage of oil and gas are often successful if combined with remote sensing. Because of the special alteration of hydrocarbons after interaction with rocks, soils and vegetation,
