AN-2型复合氧化缓速酸的研究与应用

AN-2 type compounds and oxidizes the study and application of the slow speed acid

针对孤东油田注聚高压井酸化解堵措施中存在的二次污染和出砂等问题,研制并应用了AN-2型复合氧化缓速酸。本文主要介绍了该缓速酸的基本作用原理、性能评价和现场应用情况。实践证明该缓速酸具有穿透深度大、解堵能力强、缓速、低伤害等优点,能达到深部解堵、防止出砂、实现降压增注的目的。

Gather to orphan east oil field note high-pressure well acid is it stop up measure secondary pollution existing and such issues as the sand,etc. happen to dissolve, had developed and used the AN-2 type to compound and oxidize the slow speed acid. This text is recommend this slow basic function principle, performance speed sour and appraised and uses the situation live mainly. Practice has proved slow speed acid this is it pierce through depth to be heavy is it stop up ability strong, slow speed, low advantage of injuring etc. to solving to have, can achieve dark department is it stop up, is it appear sand, is it step down the purpose to increase note to realize to prevent to solve. Compared with the situation that other complex oxidizes the slow speed acid, this is sour in slow speed performance in slow speed, show speed sour choice, prevent acid from melt two precipitate, multi-functional highefficient acid take auxiliary and on-the-spot construction craft have certain emergent novelty and practicability of initiator, and solve and stop up and increase the note result remarkably.
