摘　　要：针对储层渗透率非均质性的研究方法一般只能代表岩心或者井底周围附近地带情况,既不能描述油藏参数区域性非均质分布特点,也不能充分反映非均质油藏里流体的实际流动状态.基于储层渗透率的7种不同非均质构型,在渗流数学模型基础上,构造二维单相反演渗透率非均质变化分布的算法,以实现结合生产动态资料确定储层渗透率非均质构型分布参数.数值算例表明,验证算法可行,精度可信.According to reservoir heterogeneity research methods classified only represent near the bottom of the surrounding area. It can't describe well nets or block reservoir parameter regional heterogeneity distribution characteristics and reflect the heterogeneity of reservoir fluid in the seepage flow characteristic. Aiming at seven different permeability of reservoir heterogeneity, under different configurations of first established mathematical model of seepage flow based on this tectonic two-dimensional single-phase inversion algorithm, distribution of permeability optimization can be realized through production dynamic material determine permeability of reservoir heterogeneity configuration parameters.
