摘要: 本文论述了松辽盆地北部杨大城子地层水中微量金属元素组成,研究了地层水中微量金属元素含量的分布特征.研究结果表明,杨大城子地层水中各种元素总的含量特征是Fe＞Sr＞Zn＞Mn＞Cu＞Ni＞Cr.Ni/Cu和Mn/Fe的比值,因地区不同具有明显的差异.平面上地层水中金属元素含量与储层的含油气性有关,含油气区地层水中金属元素含量高,接近含油气区次之,远离含油气区最低.

Abstract: This paper discussed the components and content distribution of trace metal elements in stratigraphic water.The result shows that the content of various metal elements is Fe>Sr>Zn>Mn>Cu>Ni>Cr in stratigraphic water of the Yangdachengzi oil-bearing formation.Ratio of Ni/Cu and Mn/Fe is obviously different in various areas.The content of metal elememts in stratigraphic water is concerned with the hy drocarbon-bearing property of reservoir on the plane.The content of metal elements is gradually decreased from oil and gas bearing areas to water bearing areas.
