摘　　要：根据等值渗流阻力法原理 ,采用电路分析方法 ,研究了水平井和分支水平井与直井混合井网条件下的产能公式 .给出了稳定渗流条件下 ,水平井与直井混合布井时常用井网──五点法井网、七点法井网和九点法井网的产能计算方法 .研究结果表明 :等值渗流阻力法适用于水平井与直井混合面积井网的渗流研究 ,具有较高的精度 ;联合井网的产能公式适用于小井网 ;According to the law of equivalent percolation resistance, the productivities of mixed well patterns of horizontal well or multilateral horizontal well with vertical well are studied. In steady flow condition, the formulae of the well pattern in common use which are 5-spot pattern, 7-spot pattern and 9-spot pattern are given. The results show that: (1) The equivalent percolation resistance law is applicable and accurate enough to be used in productivity calculation of horizontal well pattern; (2) The productivity of mixed well pattern can be used to small well pattern; (3) The production formulae constructed in this paper are based on area well pattern, which can be applied to development program design and performance prediction.
