Abstract

Accurate prediction of the imbibition of fluid in pores would help to properly estimate the oil/gas recovery. This study is focused on imbibition estimation, considering the influences of various rock matrix properties. We summarized the mathematical models and the impact of parameters that strongly influence the imbibition. Also, it includes imbibition mechanisms that incorporate intrinsic petrophysical parameters. This review highlights the importance of considering different methods for analyzing the effect of imbibition on hydrocarbon production, thereby providing valuable insights into reservoir engineering and petrophysics. Failing to account for the pore interconnectivity in the model can result in significant discrepancies between predictions and historical data. The findings show that a higher volume of oil pores in a formation minimizes the capillary pressure. Integrating various physical and chemical mechanisms into a single numerical model allows for a comprehensive understanding of spontaneous imbibition in clay-rich shale. By addressing complex pore structures and interactions, presented models provide valuable insights for improving hydrocarbon recovery in unconventional reservoirs.

自吸和流体饱和度测量的机理认识和数学进展：综述

准确预测流体在孔隙中的吸胀作用，有助于正确估计油气采收率。考虑到不同岩石基质性质的影响，本研究的重点是渗吸估算。总结了影响吸积的数学模型和参数的影响。此外，它还包括包含固有岩石物理参数的渗吸机制。这篇综述强调了考虑不同方法来分析渗吸对油气生产的影响的重要性，从而为油藏工程和岩石物理学提供了有价值的见解。如果模型中没有考虑孔隙的连通性，可能会导致预测结果与历史数据之间存在显著差异。研究结果表明，地层中油孔体积越大，毛管压力越小。将各种物理和化学机制整合到一个单一的数值模型中，可以全面了解富粘土页岩的自发渗吸。通过解决复杂的孔隙结构和相互作用，所提出的模型为提高非常规油藏的油气采收率提供了有价值的见解。
