Parameter inversion math model for the determination of the reservoir permeability heterogeneity change based on production data

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.
