This technology widely is suitable for the enrichment of platinum and palladium from silver electrolyte or the solution that leached out gold with the sodium chlorate,especially it is suitable for complicated solution that platinum and pallad.

It is mainly to research the compound karst developmental mechanism between the two soluble rocks,which are involved in the chemical karstification and the biological karst processes.

These case examples include: Reservoir characterization and productivity evaluation by using NMR logging, determination of reservoir porosity in complex lithology, identification of oil, water and gas zones under complex reservoir conditions where resistivity log data give poor indication, guiding the.

The kinetic mechanism of the rock with acid and the fracturing methods of complex lithology,on which people have little knowledge,have much different from common carbonate formations.

Based on complex lithology reservoir eveluations and combined with reservoir structure and geology characteristics,analyzed are log responses in the abnormal compressional belts,and hense the purposeful or corresponding log interpretations are made.
