Progress of Development and Application of Drag Reduction Agents for Slick-Water Fracturing

Abstract Fracturing technology is the key of shale oil and gas exploitation in United States. The hydraulic fracturing lies formulation fluid, which can improve permeability layer, reduce pumping resistance, optimize production conditions, strata damage other purposes. Slick-water widely used water-based for unconventional exploitation, friction resistance. As core slickwater reducer determine fluid’s performances. Combining with related literature at home abroad, this paper analyzes mechanism reducer, introduces research application progress natural polysaccharide, surfactant polyacrylamide. It considered that both instant powder polymer W/W dispersion have great potential. high-efficiency sand-carrying salt resistance focus future research.
