The use of salt saturation mud and hydraulic mixer has actual direction meanings to Zhangxian County Salt Mine in the future.

By studying its conductive mechanism of occurrence and mud invasion mechanism in different fractures, corresponding saturation equations are deduced by fine division of reservoir types.

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.
