Study On Hydraulic Fracturing Technology Of "Overpressure"

In order to ensure that production of daqing oil field to succeed,for high yield,high abundance ratios district as the goal,since the 20 th century,river become one of the periphery of changyuan key off exploration areas,especially in recent years,gradually become the main targets of exploration.The research shows that linjiang region is equipped with the key exploration zone for the formation of 5000 x 104 t reserve scale potential.Face for "super under-voltage",low temperature,easy to vomit after pressure of proppant fracturing technology at home and abroad has also without precedent,and there is no mature experience can reference the status quo,this paper takes the riverfront fu Yang reservoir as the research object,by studying the riverfront plane arrangement of the exhibition,reservoir effective thickness of reservoir sand body distribution,fluid properties,reservoir temperature characteristics,the reservoir pressure characteristic understanding of reservoir characteristics,reservoir rock and character description of physical properties,water distribution characteristics of oil and gas,the reservoir fracture development situation to understand the riverfront fu Yang "super under-voltage" reservoir geological survey for the solid foundation for the next step work.Selection directly affects the pressure fluid fracturing effect,therefore,through optimizing thickener,clay stabilizer,energized,cleanup fracturing technology and viscous crude oil,low temperature helped Yang,prevent cold damage reservoir fracturing technology,and ensure the fracturing effect,and through the experimental analysis and research the optimization of fracturing construction craft,high and stable yield for daqing oilfield provides a powerful technical support.
