| 摘 要： | 通过对孤东油田馆上段四日进109块岩样中的Ca,Mg,Sr,Cr.Cu,Fe,Mn,V,Ni等九种元素的分析,得出了孤东油田馆陶组上段微量元素含量及其比值与氧化还原、湖盆盐度、古气候等沉积条件的关系,从而提供了利用微量元素及其比值的变化分析沉积环境,划分微相类型及判断古盐度高低的一种新方法.

| Abstract: | Nice trace elements of 109 rock samples from four wells of upper Guantao formation in Gudong oilfield were analyzed. The relationship among element contents and their ratios, oxidizing conditions, salinity of lake basin and ancient climate was studied. A method for analysis of sedimentary environments by using trace element contents and their ratios was presented. In this way the microfacies types of the formation could be divided and salinity could be determined. |
