发明名称 Nitrogen/carbon dioxide combination fracture treatment
摘要 There is provided an apparatus and a method of fracturing an underground formation penetrated by a well bore comprising the steps of forming a first pressurized stream of liquified gas, introducing proppants into the first stream for transport of the proppants in the first stream, pressurizing and cooling the proppants to substantially the storage pressure and temperature of the liquified gas prior to introducing the proppants into the first stream, forming a second pressurized stream of gas and admixing the first and second streams to form a fracturing fluid for injection into the formation at a rate and pressure to cause the fracturing thereof.
