Block in the test run, with the relevant core information confined contrast, moving the remaining oil to determine the extent of error saturation.

通过在试验区块的运行，与相关的密闭取芯资料对比，确定可动剩余油的饱和度的误差范围。

A core taken so as to preserve the in-situ water saturation of the rock. A native-state core is usually drilled with oil-base mud or crude oil from the same reservoir.

使用油基泥浆或原油钻取的岩心，以保证岩心的含水饱和度与岩石在储集层状态的含水饱和度相同。
