摘　　要：从低渗透油层酸化改造现状入手,跟踪调研了中外酸化改造新技术,概括总结了砂岩深部酸化工艺、前置液酸压工艺、泡沫酸酸压工艺和油乳酸酸化工艺的特点、施工工艺及其应用。介绍了高温酸化添加剂的研究新进展,并针对中国低渗透储层特点提出了酸化改造方面的建议。Beginning with the present situation of acidizing techniques in the low-permeability reservoirs, new acidizing technologies at home and abroad are investigated and researched. Characteristics , technological process and application of some technologies are summed up including the technique of sandstone depth a-cidizing,pad acid fracturing,foamed acid fracturing,emulsified acid acidizing. Progress of additive for high-temperature acidizing is then introduced. Several proposals for acidizing techniques in the low-permeability reservoirs are tabled.
