| 中文摘要:页岩气是一种分布广泛且储量丰富的非常规能源，但由于其储层具有孔隙度小及渗透率低等特性，一直以来页岩气未得到大规模开采。直到近20年，页岩气开采技术才得到飞速发展，这主要得益于水力压裂技术的进步。压裂液是水力压裂的重要组成部分，其性能的优劣直接影响水力压裂施工的成败。通过调研国内外文献，结合国内外压裂液技术的发展历程，分析了页岩气开采中几种常用压裂液的优点、适应性及存在的问题，综述了两类新型的无水压裂技术。结合我国页岩气储层的特殊性及压裂技术发展的现状，提出了适于我国页岩气开采的压裂液技术发展的建议，并特别强调了在页岩气开发初期重视环保的重要性。 |

| Abstract:As an unconventional energy, shale gas is widely distributed with abundant reserves. However, because of the low porosity and low permeability in reservoir, shale gas has not been large-scale extracted. Until the past 20 years, shale gas mining technology is developing rapidly, which is mainly due to the progress of hydraulic fracturing technology. Fracturing fluid is an important part of the hydraulic fracture treatment and its performance directly affects the success of hydraulic fracturing. Based on the investigation of domestic and abroad literatures, combining with the developing course of fracturing fluid technology in China, the advantages, adaptability and existing problems of several commonly used fracturing fluids in shale gas exploitation are analyzed, and 2 new anhydrous fracturing technologies are summarized. Combined with the particularity of the shale gas reservoir and fracturing technology development status in China, suggestions suitable for China's shale gas fracturing fluid technology development are put forward and the importance of paying attention to environmental protection in the preliminary stage of shale gas is emphasized. |
