摘　　要：合理的井网是油田开发所面对的最重要的问题之一。不同规模的河道砂体,开发所需要的井网密度是不同的。研究表明:大型河道砂体规模较大,井网加密后河道形态变化较小,基础井网时就能控制住砂体的分布特征。一次加密井网能控制住中型河道砂体的分布特征,小型河道砂体,砂体不发育,只有二次加密或聚驱井网时,河道砂体的分布才能控制住。其研究成果对油田开发方案制定及开采措施调整具有重要的意义。The rational well density is one of the most important questions in oilfield development. The well density is different for distinct scale river channel sand. The study indicates that the change of large river channel sand pattern is small when the well density is becoming larger,the basic well net can control the distribution characteristics of river channel sand,the once encryption well net can control the distribution characteristics of middle scale river channel sand,only the secondary encryption well net can control the distribution characteristics of little scale river channel sand. This research is very important for making scientific development plan and adjusting exploiting methods.
