随着深层超深层储层改造技术的发展，对超高温压裂液提出了迫切的需求。10年来我国开发的超高温压裂液按稠化剂类型主要分为三类：超高温羟丙基瓜尔胶压裂液和羧甲基羟丙基瓜尔胶压裂液、超高温改性瓜尔胶和聚丙烯酰胺混合基压裂液、超高温合成聚丙烯酰胺压裂液。本文介绍了近10年来这三类超高温压裂液技术在 我国的研究应用和最新进展，指出了这些压裂液的缺点和局限性，提出了超高温压裂液技术的研究方向。参33

With the development of deep/super-deep reservoir stimulation technology，urgent demand was proposed for ultra-high temperature fracturing fluid. In the last decade three different ultrahigh-temperature fracturing fluids were developed in China， including hydroxypropyl guar or carboxymethyl hydroxypropyl guar，modified guar gum and polyacrylamide，and synthetic polyacrylamide. The domestic applications and the latest development of three ultra-high temperature fracturing fluid technologies were introduced in this paper. The disadvantages and limitations of these fracturing fluids were summarized. Finally the research direction and keys to develop ultrahigh-temperature fracturing fluid were suggested.
