由于流动单元定量研究中常用的数学方法不能反映储层的地质分布规律,采用了地质条件约束的研究思路,对塔中油田塔中11油藏志留系潮坪相储层进行了流动单元研究.在应用高分辨率层序地层学进行小层对比的基础上,首先确定储层内部的渗流屏障及连通体的分布规律,然后在连通体内部,综合采用基于孔渗的宏观参数FZI和微观参数R35建立流动单元的聚类样本和判别函数,对所有取心井和非取心井划分出流动单元类型.最后根据单井划分结果,在储层结构模型的约束下,优选随机建模方法对流动单元的分布进行横向预测,建立了流动单元分布的三维模型.实践证明,渗流屏障和连通体等地质条件控制下流动单元定量研究方法在潮坪相地层中有很好的应用效果.  相似文献

Abstract-The study area lies in the subaqueous delta, which came into being in 1964～1976. Oneoil-field road has been built for exploring petroleum to form a wave barrier. The hydrodynamic conditionson the north side of the road are relatively violent, on the contrary the hydrodynamic conditions on thesouth side of the road are nearly placid. This makes the study area a natural laboratory for studying theinfluence of the hydrodynamic conditions on the fractal characteristics of the tidal flat. Selecting an areais named Case Ⅰ on the side of stronger hydrodynamic activities and an area is named Case Ⅱ on the otherside. Measuring the topography and sampling and analyzing the granulometrical comoposition, it is foundthat the hydrodynamic conditions have fatal influence on the surface fractal dimensions and the granulo-metrical fractal dimensions of the area. In Case Ⅰ, which has strong hydrodynamic conditions, the sur-face fractal dimensions are obviously large than those of Case Ⅱ, and the granulometr  相似文献
