摘要
报道了将复合固体酸酸化用于解除稠油井堵塞的技术。概括介绍了复合固体酸的基本组成（ 有机酸、潜伏酸及多种添加组分） 和性能指标、作用原理、解堵工艺，详细介绍了用复合固体酸解除辽河油田锦４５ 块稠油井堵塞的效果。
This paper describes the uses of mixed solid organic/latent acids in aqueous solution for acidizing viscous oil producing wells to relieve the organic/inorganic precipitates blocked in the reservoir strata. This acidizing fluid composed of solid organic and latent acids and such ingredients as compatibilizer, hydrocarbon solvent, reaction controller and adjuster. The field tests in 10 wells at Block Jingzhou 45 are presented in detail and one operation is examplified.
