摘要
常规酸化压裂工作液体系存在酸岩反应过快、有效作用距离短等问题,微胶囊固体酸是解决该问题的有效手段之一,其常用于对非常规油气藏进行深度酸化压裂。此次研究阐述了微胶囊固体酸的作用机理、结构和性能特点,总结了微胶囊固体酸酸化压裂技术的研究进展,指明了微胶囊固体酸酸化压裂技术未来的主要研究方向。该研究可为超高温碳酸盐岩油藏的增产改造提供技术支持,并为微胶囊固体酸酸化压裂技术的研究与应用推广提供理论指导。
The conventional acid fracturing working fluid system has problems such as too fast acid-rock reaction and short effective distance,the microencapsulated solid acid is one of the effective means to solve this problem,and it is commonly used for deep acid fracturing of unconventional oil and gas reservoirs.This study describes the mechanism of action,structure and performance characteristics of microencapsulated solid acids,summarizes the research progress of acid fracturing technology with microencapsulated solid acid,and indicates the main research directions of acid fracturing technology with microencapsulated solid acid in the future.This study can provide technical support for the stimulation of ultra-high temperature carbonate reservoirs,and provide theoretical guidance for the research and application promotion of acid fracturing technology with microencapsulated solid acid.
