Progress in application of nanoparticles in hydraulic fracturing of unconventional reservoirs

本文综述了纳米颗粒在非常规储层水力压裂中的应用现状,重点介绍了纳米颗粒的作用机理、应用、研究成果、技术挑战和未来研究方向。并指出纳米材料在改善粘弹性表面活性剂流体、泡沫基流体和聚合物基压裂液流变学方面的应用前景。以往的研究结果表明,纳米材料具有尺寸小、比表面积大、磁性能强、强度和稳定性好等独特的性能,可以应用于井下纳米传感器、纳米支撑剂、破胶剂和降滤失剂的开发。

In this paper, the application status of nanoparticles in unconventional reservoir hydraulic fracturing is reviewed, with emphasis on the mechanism, application, research achievements, technical challenges and future research directions of nanoparticles.The applications of nanomaterials in improving rheology of viscoelastic surfactant fluids, foam-based fluids and polymer-based fracturing fluids are reviewed.Previous research results show that nanomaterials have such unique properties as small size, large specific surface area, strong magnetic properties,good strength and stability, which can be applied to the development of downhole nano-sensors, nano-proppant, gel breaker and filter loss agent.
