摘　　要：以土酸、柴油、表面活性剂等为原料,研制出一种油包酸型抗高温乳化酸,并对其性能进行了评价。结果表明,该乳化酸能抗80℃高温,可以满足深井酸化的需要;具有缓蚀、防腐等优良性能,有利于深部酸化;且黏度较低,可泵入性好。An acid -in- oil emulsified acid with high temperature -resistance was developed using soil acid, diesel oil, and surfactants as raw materials. The performances of the emulsified acid were evaluated and the results showed that the emulsified acid had high temperature resistance of up to 80℃ and met the needs of acidizing deep well. The emulsified acid also had excellent properties of corrosion inhibition and anticorrosion, which was helpful to deep acidification. The emulsified acid had low viscosity and good pumping ability.
