高温低渗油气田的压裂开发对我国油气资源的可持续发展具有重要意义。开发在 240℃储层保持良好流变性和携砂能力的压裂液体系已列入 “十三五” 国家重大科技专项研究内容。本文综述了近年来耐温 170℃以上的压裂液体系， 分别分析了植物胶压裂液、 聚合物压裂液、 复配压裂液及耐温交联剂的特点， 并对耐温 240℃压裂液的开发提出建议。参 40

The exploitation of high-temperature and low-permeability oil and gas fields is of great significance to the sustainable developments of china's oil and gas resources. The‘13th Five-year’major national research and development projects require the development of a fracturing fluid system with reliable rheological and sand-carrying properties for application in 240℃ reservoirs. In this paper， the fracturing fluid systems with temperature tolerance above 170℃ were reviewed. The characteristics of vegetable gum fracturing fluid， polymer fracturing fluid， mixed fracturing fluid and temperature tolerant cross linking agents were analyzed， respectively. Suggestions for the development of 240℃ fracturing fluids were put forward.
