The aqueous fluid in subduction zone has played important role for the evolution of crust and mantle and the mass exchange.

During the formation of stalactite and stalagmite in karst caves carbonate minerals often trap gas and aqueous fluids, forming immiscible fluid inclusion population when they are crystallizing.

The item investigates the fracturing fluid system using in deep well fracturing in Xinjiang oil field, and optimizes suitable aqueous fracturing fluid system and fracturing fluid additive.
