清洁压裂液的研究现状与展望

粘弹性表面活性剂(VES)压裂液是一种无聚合物压裂液,又被称为清洁压裂液。它与传统的压裂液相比较具有破胶彻底、对地层伤害低、摩阻压力小等特点。介绍了VES压裂液的基本原理,综述了国内外的研究与应用现状,探讨了VES压裂液目前还存在的缺陷并对未来的发展趋势做了展望。

Research Status and Prospect of Cleaning Fracturing Fluid

Viscoelastic surfactant (VES) fracturing fluid is a polymer-free fracturing fluid, also known as cleaning fracturing fluid. Compared with the traditional fracturing fluid, it has many advantages, such as low damage to the formation, low friction pressure and so on. In this paper, the basic principle of VES fracturing fluid was introduced, its research and application status at home and abroad were summarized, the existing flaws of VES fracturing fluid was discussed, and its future development trend was prospected.
