摘　　要：文章报道了一种新型的低伤害压裂液体系,该低伤害压裂液体系在100℃时具有良好的抗剪切性能,剪切2h后仍然在220mPa.s以上,且残渣率仅为2.4%。岩心基质伤害实验和导流能力伤害实验表明该体系能有效降低储层伤害,保持较高的裂缝导流能力。该压裂液已在华北油田获得成功运用,从现场应用情况看,增产倍比均为3以上,效果十分显著,具有很好的应用前景。A new low damage fracturing fluids system was de-veloped. The researched fracturing fluids system have the excellent ability to resist shear at 100℃ and the viscosity is above 220 mP. s after shearing 2h with 170s'. The residue rate is only 2.4%. The research of core based damage and flow conductivity showed the frac-turing fluids could reduce the reservoir damage effectively,keep ex-cellent fracture conductivity. The fracturing fluids have been used successfully in 4 wells in Huabei oilfield,the production was in-creased and had good application prospects.
