发明名称 High proppant concentration/high CO2 ratio fracturing system
摘要 There is described 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 fracturing fluid, introducing proppants into the second stream for transport therein, and admixing the first and second streams to form an emulsion for injection into the formation at a rate and pressure to cause the fracturing thereof.
