摘　　要：在总结下黄岩区块各项开发地质条件的基础上,通过合理储量法、经济极限井距法、模拟法等对研究区的井网井距进行优化,最终认为开发井网方向沿N60°E和N30°W,按300m×250m进行布置最优,有利于取得较好的经济效益,提高资源的利用率。Based on the geological conditions of Xiahuangyan block,we used reasonable reserve method,economic limit well spacing method and simulation method to determine the development well network as N60°E direction 300m,N30°W direction 250m as the development well pattern.This kind of well pattern can not only achieve better economic benefits,but also improve resource utilization.

关 键 词：井网 井距 优化
