摘要
酸蚀蚓孔效应作为影响酸压中酸液滤失的一个重要因素,已经引起人们的重视。国内外学者在酸蚀蚓孔效应的形成机理、影响因素以及考虑蚓孔效应的酸液滤失模型方面进行了大量的研究,到目前,国内外关于酸化压裂设计中的蚓孔动态扩展模型的研究还很少,并且现有的蚓孔模型在应用上也有一定的局限性。据此就目前国内外在酸蚀蚓孔效应方面的研究工作进行了概括总结,并提出了现存的问题和今后研究的重点,对研究酸压中的滤失问题及蚓孔模型的建立有一定的指导意义。
As an important factor affecting acid leak-off in carbonate reservoir,acid wormhole has been concerned.Many scholors,both home and abroad,have made a lot of researches on the formation mechanism of acid wormhole and affecting factors and models of acid wormhole.So far,researches on acid wormhole models of acid fracturing are few.Furthermore,the existing models have their limitations in application.This paper summarized the studies of acid wormhole at home and abroad,and put forward the existent problems,which can be beneficial to the study of acid leak-off and the establishing of acid wormhole models.
