摘　　要：疏松砂岩油藏如果应用土酸解堵工艺容易造成出砂,而应用盐酸工艺,不仅可解决出砂难题,而且也有利于解除临盘油田改性水对油藏的钙质堵塞。本篇文章先分析了盐酸酸化的原理,然后介绍了在临盘疏松砂岩油藏应用盐酸解堵工艺的成功实例。Unconsolidated sandstone reservoir was easily caused sand when the technology of acidization by mud acid was used.The acidization by hydrochloric acid not only can solve sand problem,but also can lift the calcium blockage caused by modified water in Linpan Oilfield.This thesis analyzed the principle of acidization by hydrochloric acid and then described successful examples of the application of this new technology in Linpan unconsolidated sandstone reservoir.
