[咨询求助]有效厚度下限的确定 [复制链接]

yinchuan:What you talk about is a traditional concept for conventional reservoir.
This concept, cutoff for Net Pay, would be taken out from our practice in the future. We already have effective porosity(PhiE) and effective Swe,so we can get net pay by parameters. There .. (2013-11-10 00:40) 

不是有隔夹层吗，这个不算吧

It is OK to use it for conventional reservoir. In this case, we like to know which part is pay or producing oil, which one is not.

For some unconventional reservoirs, especially, when using Fracking technology, all zones will be fractured and be part of producing zones. No pay zone or tight zone can be defined by the lower or no porosity. In this case, reserves is the function of  PhiE*So*H. There is no need to use the porous zones and take out the tight zones by using a cut-off.

真的不错
