多尺度信息用于精细地质建模——以大庆升平155油田为例
|
摘要
通过结合地震、测井和地质研究成果,充分发挥地震资料和井资料分别在平面和纵向上具有高密度采样的特点,依据一定的相模式,选取建模参数,采用基于目标的目标层次建模方法和基于象元的序贯指示模拟方法,逐层建立沉积微相的分布模型;以地质统计学为手段,以与物性具有较好相关性的地震软信息为协约束,利用相控随机建模技术,建立了定量描述储集层孔隙度、渗透率及有效厚度物性空间分布的精细三维地质模型。
Through combination of seismic,well logging and geological research,wide use of the seismic data and well data in the vertical plane with a high-density characteristics of the sample,based on a certain phase mode,the model parameters are selected.Based on the target,the goal-level modeling and pixel-based simulation of sequential instructions are adopted,then step by step the establishment of micro-deposition phase of the distribution model is made.With geostatistics and better physical properties of earthquake-related information for the soft-bound Association,A fine three-dimensional geological model of quantitative description of the reservoir porosity and permeability and the effective thickness of the physical properties of the spatial distribution is established by usinghte modoling technique.
