Characteristic analysis of polymer for slick-water fracturing fluids
Shale gas development requires volumetric fracturing.Compared with guar gum system,slick-water fracturing fluid is becoming a common fracturing fluid technology in shale gas exploitation due to its low pump pressure and easy viscosity adjustment.Shale gas resources are abundant in southwest China,and the slippery water system with polymer as drag reducing agent is now used.The injection volume of a single well is tens of thousands of square meters and the displacement is 16～20 m3/min,which puts forward higher require-ments on the cost of slippery water.Therefore,the characteristic analysis of polymer used in slick-water fracturing fluid provides important technical support for the development in shale gas and shale oil.
