为了充分利用已有的非定量分析孢粉资料,开展孢粉相及孢粉与烃源岩关系研究,引入“孢粉相对密度”概念,定义为孢粉样品鉴定中每个盖片数的孢粉个数。根据牛28井相同井段对比分析,孢粉相对密度的变化趋势与地层中孢粉实际含量的变化趋势一致。以东营凹陷古近纪为例,探讨了孢粉相对密度在石油地质中的应用。可以利用孢粉相对密度进行层序划分对比,孢粉相对密度在区域上的变化具有同步性。通过对孢粉相对密度在横向上分布规律研究,能为研究孢粉量的区域分布特征提供依据。
In order to make full use of the existing non-quantitative analysis of sporopollenic data, the study on the relationship between sporopollen and sporopollen and source rock was carried out. The concept of relative density of sporopollen was introduced, which was defined as the number of each cover in the identification of sporopollen The number of spores. According to the comparative analysis of the same well section in Well Niu 28, the trend of the relative density of sporopollen is consistent with the change trend of the actual content of sporopollen in the formation. Taking the Paleogene in Dongying depression as an example, the application of relative density of sporopollen in petroleum geology was discussed. The relative densities of sporopollen can be used for sequence division and comparison. The relative density of sporopollen in the region has the same change. The research on the horizontal distribution of the relative density of sporopollen can provide the basis for studying the regional distribution of the amount of sporopollen.
