摘要：水力压裂技术是最常见的储层改造关键技术,支撑剂的铺置运移对天然裂缝的活化和人工裂缝的形成有巨大影响,因此研究支撑剂在裂缝中的运移规律对优化裂缝内砂堤形态,改善压裂效果具有重要意义。针对该规律的研究,可视化支撑剂运移装置随着研究的展开也不断改进,目前有单缝、二级缝、复杂缝等多种装置,各有优缺点。未来朝着设计一套能够模拟真实地层条件下支撑剂运移和导流的可视化实验装置及系统的方向努力,一步步缩小室内实验与现场实际情况的差距,揭示出支撑剂在实际裂缝中的运移规律。Hydraulic fracturing technology is the most common key technology for reservoir reconstruction. The placement and transport of proppant has a great impact on the activation of natural fractures and the formation of artificial fractures. Therefore, it is of great significance to study the transport law of proppant in fractures to optimize the shape of sand banks in fractures and improve the fracturing effect. In view of the study of this law, the visual proppant transport device has been continuously improved with the development of research. At present, there are many kinds of devices such as single seam, secondary seam, and complex seam, each of which has advantages and disadvantages. In the future, efforts should be made to design a set of visual experimental devices and systems that can simulate proppant transport and diversion under real formation conditions, step by step to narrow the gap between laboratory experiments and the actual situation in the field, and reveal the law of proppant transport in actual fractures.
