摘要
综述了上世纪60年代以来酸化液助排剂及酸化液、压裂液及其他水基地层处理液多功能助排剂的发展历程。列表给出了文献报道的、目前国内外应用的12种主要酸化液助排剂的基本组成和技术性能。讨论了酸化液及水基处理液的发展趋势及存在问题。综述了目前国内形成的3种返排技术,即:注液氮层内助排;连续油管液氮气举助排;抽汲助排。
The development of acid cleanup additives （ACAs） and multifunctional cleanup additives for backflow of acidizing, hydrofracturing, and other water base reservoir treating fluids is presented historically starting from 1960s. The basic composition and the technical features of 12 main ACAs used in China and abroad and published in periodic.aN are tabulated. The tendencies and the problems in developing cleanup/backflow additives are discussed. The cleanup/backflow promoting technologies developed in China are presented and these are： squeezing liquid nitrogen into the reservoir formations; gas lift by the way of injecting liquid nitrogen through coiled tubing; and swabbing.
