请问下：
稠油氮气混相驱用eclipse里的哪个模拟器？
能不能用black oil，外加IOR里面的misible gas flood？

Thank u very much,ytlee!Every time i can get ur help.

if it is N2 immisible flood,Can I use the black oil model?

[ytlee]

use ec300 only.

Technically, you can use BO and treat the N2 as light gas (as gas injection) only if N2 is immisible.

However, the spirit of simulation is to simulate the physical world. If it invalid the physical rules, that is not simulation.

In the physical world, how do you prevent the N2 not mixing with the oil?

N2 is not cheap, if it can't improve the fluid mobility, why use N2?




Using ec300 gives you an alternative in case you change your mind regarding n2 immisibility.

Thank u very much,ytlee.

Ur answer give me a light!

I wanna know,if N2 is immisible,can i make the other combinations 0 percent in E300?

I believe there is an example case (case1asp??) in the installation folder. please check it out.

BTW, if your study is for a real world field, there is no 100% N2. Depending on pressure and temperature, N2 may be heavier than reservoir fluid, therefore, you need to consider the placement of the injector. Also N2 is corrosive, protection of the pipe must be evaluated.
