滑溜水压裂液用降阻剂的研究与应用进展

Progress of Development and Application of Drag Reduction Agents for Slick-water Fracturing

滑溜水作为非常规油气开采应用最多的水基压裂液之一,其主要特点是能够降低摩擦阻力,而降阻剂作为核心助剂决定了滑溜水的性能和应用。本文结合国内外相关文献,分析了降阻剂的作用机理,介绍了天然聚合物型、表面活性剂型以及聚丙烯酰胺型降阻剂的研究及应用进展,认为速溶粉式聚合物降阻剂和W/W分散聚合物降阻剂具有较大应用潜力,能够实现高效携砂且耐盐的降阻剂是未来研究的重点。

Slick-water is widely used in water-based fracturing for unconventional oil and gas exploitation,which can reduce the friction resistance.As the core of the slick-water fracturing fluid,the friction reducer determine the fluid’s performances.Combining with the related literature at home and abroad,this paper analyzes the mechanism of friction reducer,introduces the research and application progress of natural polysaccharide,surfactant and polyacrylamide.It is considered that both the instant powder polymer and W/W dispersion polymer have great application potential.The friction reducer with high-efficiency sand-carrying and salt resistance is the focus of future research.
