请问我网格个数12*40*1，尺寸2.5cm*2.5cm*1cm，一共建立了三口水平井，一口注入井，一口注水井，一口生产井，设置的各参数也在合理范围，为什么注气井的井底流压总是不收敛呢？如果把模型长宽高都放大100倍，单个网格尺寸为25m*25m*1m就可以收敛了，请问有什么办法解决小模型呢？谢谢

检查一些 井的注入强度 注入体积 和 网格体积的比 是否一致

replied 9月 ago 你好，我的注气井和注水井都设置的0.00144m3/d（1ml/min），注入时间设置的10hour，今天我把水平井换成了直井，然后没说井底流压不收敛，但是模型也没有跑通，又说压力组分饱和度变化太大，模型不收敛。请问是什么原因呢？谢谢
