摘要
酸化是油气井增产的主要措施之一,而酸化反应机理是进行酸化施工的依据。重点综述了用于砂岩储层酸化的盐酸、磷酸、氢氟酸、氟硼酸以及多氢酸体系,并简单介绍了碳酸盐岩反应机理,对优化酸化设计有一定的指导作用。
Acidizing is one of the major measures of oil - gas well stimulation, but acidizing treatments depend on acidizing reaction mechanism. The acid systems which used in Sandstones, such as Hydrochloric acid, Phosphoric acid, Hydrofluoric acid, Fluoroboric acid and Multi - Hydrogen acid were reviewed, and Carbonates reaction mechanism was summarized. The results had guidance in optimizing acidizing design.
