支撑剂运移是水力压裂过程中的一个重要物理过程，在石油工程中广泛应用于储层改造。与压裂液一起注入的支撑剂为受刺激的裂缝网络提供结构支撑，并防止它们在返排后闭合。因此，支撑剂在裂缝网络中的最终分布直接影响水力压裂的效果。由于测井的局限性和高成本，计算模型已越来越多地用于研究支撑剂输送，其中采用不同的假设和数值模型，通常没有严格的验证或理由。这项工作提出了一个全面的审查支撑剂运输建模，从相关的物理数值方法，旨在提供一个公正的全球图片的最先进的研究，激发新的见解，并促进创新和可靠的计算模型的发展支撑剂运输。
Proppant transport is a critical physical process in hydraulic fracturing which has been extensively used for reservoir stimulation in petroleum engineering. Proppants injected together with fracturing fluid provide structural support to the stimulated fracture network and prevent them from closing after flowback. Hence, the final proppant distribution in fracture networks affects directly the effectiveness of hydraulic fracturing. Owing to the limitation and high cost of well logging, computational modelling has been increasingly used to study proppant transport, where different assumptions and numerical models have been employed often without rigorous validation or justification. This work presents a comprehensive review on proppant transport modelling, from relevant physics to numerical approaches, aiming to provide an unbiased global picture of the-state-of-the-art studies, inspire new insights, and promote the development of innovative and reliable computational models for proppant transport.
