| 摘 要： | 砂岩地层酸化是改造地层的一种有效手段，但对砂岩地层酸化的同时，又可能形成油湿地层、粘土分散和絮结、界面薄膜和粘稠乳液对地层造成伤害。合理的酸化规模和快速排液有利于减轻对地层的伤害，同时也应注重选择使用合适的表面活性剂，以预防和减轻钻井滤液及酸化施工入井液或是表面活性剂本身可能对地层的伤害。

| Abstract: | Acidizing is an effective method of rebuilding formation in sandstone formation, but it can also bring formation damage taken by forming oil-wetting formation, clay dispersing and flocculating, interfacial film and stringy milk. Rational acidizing scale and quickly flowing in reverse is advantageous to reduce the formation damage, meanwhile selecting appropriately surface active agent can prevent and reduce the formation damage by well boring filter liquor, acidizing liquid and surface active agent. |
