根据近几年注水井酸化实践,本文分析总结了砂岩储层在酸化前及酸化过程中的常见损害及其处理方法,提出了预防酸岩反应过程中形成二次损害的对策,预防酸化过程中形成新沉淀是提高酸化效果的一个重要方面.%According to practice of injection wells acidification in recent years, this paper analyzed and summed up the common damage of sandstone reservoir before acidification and acidification process as well as its processing methods, and proposed countermeasures for preventing the formation of secondary damage in acid rock reaction process. To prevent the formation of new precipitate in acidification process is an important aspect to improve the acidification effect.
