| 摘 要： | 叙述了石油上方重金属元素的射流晕分布特点，形成机制，研究方法及其可能的应用，地球深部存在大量的气体，即地气，而且地球存在排气作用。在与石油层接触的地下水中，重金属(V,Ni,Cu,Pb,Zn等）离子的浓度比其它地方要高得我,铛气体以微气泡的形式向地球表面运动时，地下水中的重金属元素可以远距离运移到达地表，并在石油层边缘上方形成重金属元素的垂直分布现象，即射流晕，同时也把地球深部的信息带到地表。因此研究石油层上方重金属元素的射流晕的分布便可以得到许多与含油有关的信息，如今油气层的水平展布等。

| Abstract: | The paper describes the feature,mechanism of formation,research methods and possible applications of jet halo of mobile heavy metal above oil bearing formation.The earth is rich in plenty of free gas(geogas)and in an ongoing process of degas.The concentration of heavy metals(V,Ni,Cu,Pb,Zn etc.)in the underground water,bordering on oil bearing formation is higher than that in other place.The heavy metals can migrate in a long distance up to the ground surface by ascending microbubble flow,and a vertical dispersion of the metals,i.e.jet halo,is formatted above the edge of oil bearing formation.The migration of metals carry some useful information about deep geological objective to the ground surface.Therefore,the information of oil bearing formation(for example,the horizontal distribution of the formation)can be obtained by the study of related jet halo. |
