摘　　要：在前人研究的基础上采用等值渗流阻力法推导了九点、七点和五点面积井网下水平井的产能公式，并分析了各影响因素对各面积井网中水平井产能的不同影响，对各井网的有效传导率、产能指数比及产能指数进行对比研究，优选出水平井五点联合井网为水平井开发最优井网。Deliverability formula for horizontal wells in 5-spot, 7-spot, 9-spot patterns are derived with application of equivalent percolation resistance method, on the basis of predecessors＇ fruits of research. Various influences of factors on deliverability of horizontal wells in various areal well patterns are analyzed. The effective conductivity, productivity index ratio and productivity index of the well patterns are compared with each other, the horizontal well The mixed 5-spot well pattern is optimized as the best one for horizontal well development.
