초록 ▼

Subterranean oil and gas producing formations are fractured by providing one or more combustion gas generating units using rocket fuel type propellants disposed in a well casing at preselected depths. The well casing is filled with a compressible hydraulic fracturing fluid comprising a mixture of liquid, compressed gas, and propant material and precompressed to a pressure of about 1,000 psi or more greater than the fracture extension pressure at the depth of the zone to be fractured. At least one of the gas generating units is equipped with perforating shaped charges to form fluid exit perforations at the selected depth of the fracture zone. The gas generating units are simultaneously ignited to generate combustion gasses and perforate the well casing. The perforated zone is fractured by the rapid outflow of an initial charge of sand free combustion gas at the compression pressure followed by a charge of fracturing fluid laden with propant material and then a second charge of combustion gas. The column of precompressed fracturing fluid is discharged into the formation until the hydraulic extension pressure is reached and eventually the perforations sanded off.

A method for fracturing a subterranean earth formation to stimulate the production of fluid from said formation wherein a wellbore extends at least to said formation from a surface point, said wellbore being provided with casing means forming a substantially fluid tight interior space, said method comprising the steps of: providing perforating means for perforating said casing means at a predetermined zone of said formation to provide for flow of fluids between said formation and said wellbore and placing said perforating means at said zone, filling at least a portion of said wellbore with a compressible fracturing fluid comprised of a liquid containing dispensed quantities of gas and having a solid propant dispersed therein; raising the pressure of said fracturing fluid in said wellbore to a predetermined pressure greater than the pressure required to hydraulically extend a fracture in said formation at said zone; and actuating said perforating means to form apertures in said casing means and concomitantly generating a high gas pressure within said fluid whereby said pressurized fracturing fluid at said predetermined pressure is allowed to flow into said formation under decompression forces to fracture said formation with a quantity of said fracturing fluid and to prop fractures in said formation open with said propant.
