摘　　要：介绍了储层各向异性对井距及布井方式的影响,推导出各向异性渗透率与各向同性渗透率的变化关系式;根据水电相似原理,推导出不同面积井网产能计算的一般关系式;最后给出了直井交错排列井网整体开发产能公式的精确表达式,进一步确定了各向异性地层的产能公式。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.
