| Abstract: | This paper addresses the influence of reservoir anisotropy on well spacing and pattern configuration,derives a relational expression between anisotropic permeability and isotropic permeability;the general relational expression of deliverability calculation for different areal patterns is derived according to the similitude principal of hydropower,and an rigor expression of deliverability for integral development with staggered pattern of vertical wells is finally presented,thus defining the deliverability formula for anisotropic reservoirs. |

| Keywords: | low permeability reservoir anisotropy permeability well pattern deliverability formula |
