Abstract: 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.

Key words: reservoir, heterogeneity, fractal, fractal dimension, model, flow unit
