以油酸酰胺丙基二甲基叔胺、过氧化氢为原料制备出油酸酰胺丙基二甲基氧化叔胺（OADO）稠化剂．研究了冰乙酸、氯化铵添加量对OADO稠化性能的影响，检测了压裂液的耐温性、耐剪切性、悬砂性、耐酸碱性和破胶性．结果表明，m（氯化铵）∶ m（冰乙酸）∶ m（OADO ）∶ m（水）为0．5∶1∶1．5∶100时，压裂液pH值为6．0，粘度可达到82 mPa · s ，70℃时可有效悬砂，剪切60 min后粘度仍大于25 m Pa · s ，当压裂液中煤油含量大于0．8％时，120 min内可完全破胶．

The thickener of oleic amidopropyl dimethyl amine oxide (OADO) was prepared by oleic amidopropyl dimethylamine and hydrogen peroxide .T he influences of the addition of acetic acid and ammonium chloride on the thickening property of OADO were studied .Mean-w hile ,the temperature resistance ,shearing resistance ,suspended sand performance ,acid and alkaline resistance and gel breaking property of fracturing fluid were also studied .The results show that the pH value of clean fracturing fluid was 6 .0 and the viscosity can reach 82 mPa · s when ammonium chlorid ,acetic acid ,OADO and water were mixed at the mass ratio of 0 .5∶1∶1 .5∶100 .T he clean fracturing fluid can suspend sand effectively at 70 ℃ and the viscosity still exceeded 25 mPa · s after shearing for 60 minutes .The fracturing fluid can break completely within 2 h when the concention of kerosene was above 0 .8% (wt .% ) .
