摘　　要：储层改造方式主要为水力压裂、基质酸化、酸化压裂,然而在20世纪80年代初,国外公司研制的新型酸液具有的携砂性能,为在储层中产生具有较高导流能力的酸蚀支撑裂缝提供可能,此后酸携砂压裂技术被越来越多地研究[1]。文章重点从粘温性、携砂性和现场应用情况三个方面,对比和分析国内外报道的携砂酸液,分别是地面交联酸、清洁酸和乳化酸。结果证明地面交联酸的耐温性,携砂情况以及现场应用效果是最好的。同时,文章在总结对比的基础上,发现了一些在携砂酸液研究中存在的问题。Hydraulic fracturing, matrix acidizing and acid fracturing are the main treatments for reservoir stimulation. However, when a foreign company came up with a new acid formula which got the ability of carrying proppants in the early 1980 s, this new acid system can create prop-fractures with high conductivity through acid fracturing with proppant. Therefore the study on acid fracturing with proppant is getting popularity. This paper compares and an-alyzes some data of cross-linked acids, VES acids and invert emulsified acids with the capacity of carrying proppants which are reported by researchers at home and abroad from three main aspects, viscosity-temperature property, capacity of carrying proppants and field application. Results show the thermal stability, ability of proppant-carrying and the effect of field application of cross-linked acids are the best. At the same time, some problems existing in the researching are mentioned.
