摘要
阐述了缓释酸的缓释机理,介绍了缓释酸体系的性能,总结了稠化酸、乳化酸、泡沫酸、自生酸、包封酸的配方及优势,详细介绍了体系中所用的聚合物、表面活性剂。
The slow-release acid system can effectively realize the deep acidification of high-temperature carbonate reservoirs.This paper describes the slow-release mechanism of sustained-release acid,and introduces the performance of sustained-release acid system.Moreover,the formuas and advantages of thickened acids,emulsified acids,foam acids,autogenous acids,and encapsulated acids were summarized.The polymers and surfactants used in the system are also introduced in detail.
