摘要
针对流动单元的划分方法提出了一套利用非均质性分维模型定量研究陆相储集层流动单元的方法和流程。该方法利用储集层非均质性分维模型有效地划分储集层宏观流动单元和微观流动单元,并为二者的划分提供参数依据;在储集层沉积微相研究和层组逐级细分对比的基础上,从取芯井入手,通过聚类分析优选参数,建立储集层非均质性分维模型,应用聚类和判别分析,划分流动单元类型,应用储集层随机建模中的分形随机模拟方法预测河流—三角洲沉积储集层井间流动单元,从而定量研究流动单元的空间展布,效果较为理想。
Based on numerous scholars investigation of flow unit,a set of method and procedure are summarized by utilizing Reservoir heterogeneity Fractol Model to quantitatively investigate reservoir flow unit in non-marine facies reservoir.It effectively plots out macro-flow-unit and micro-flow-unit of reservoirs by using Reservoir heterogeneity Fractol Model and supplies parameter evidence for the division of macro and micro flow unit of reservoir.It builds Reservoir heterogeneity Fractol Model through cluster analysis and parameter optimization,starting from drill core sample,based on research of reservoir sedimentary facies and subdivision and correlation step by step of series of strata.It applies clustering and discriminatory analysis to divide category of flow unit,forecasts inter-well flow unit in reservoir of fluvial-deltaic deposition by means of reservoir fractal stochastic simulation method in order to quantitatively study spatial distribution characteristic of flow unit.It has acquired more ideal effect.
