中文摘要：

LPG流体具有密度低、黏度和表面张力小等特点,因此LPG压裂液具有较好的造缝和携砂能力并且能有效降低流体对储层的伤害。针对中国当前在页岩气开发中所面临的制约因素,结合LPG压裂液在压后返排、增产稳产、储层保护和运输储存等方面的优点,分析了LPG压裂技术在中国未来页岩气开发中的应用前景,认为LPG是一项省地、省水、绿色环保的新型压裂技术。LPG压裂技术在国外的成功应用有望为中国页岩气开发提供新的途径和思路。

英文摘要：

The inherent features of LPG fluid like low density, low viscosity and low surface tension make the LPG fracturing fluid has better fracture initiation and proppant carrying capacity and can effectively reduce the for- mation damage. Combining the current constraints in shale gas development in China and the advantages of LPG frac fluid in frae fluid flowback, enhanced oil recovery, formation protection and transport and storage, the application prospect of LPG fracturing technology in future shale gas development in China is analyzed. LPG fracturing technolo- gy is seen as a footprint reduction, water saving and green fracturing technology. The successful application of LPG fracturing technology in foreign countries is expected to provide new approaches and ideas for China shale gas development.
