Abstract

Abstract:

Based on the coupling method of the Navier?Stokes equation and phase field theory, the pore scale numerical model for fractured mixed?wet tight reservoir is established to investigate the oil recovery process under different injection velocities, injection modes, and injection?shutdown durations. The findings indicate that the injection velocity has a nonlinear correlation with the oil recovery, with an optimal velocity of 0.01 m/s, where the dynamic equilibrium between capillary force and viscous force achieves the highest fracture?matrix pressure transfer efficiency, leading to a peak recovery degree. The periodic intermittent water injection demonstrates a 48% reduction in water usage compared to constant rate injection, with a slight 1.08% reduction in recovery, making it more economical under low oil prices. The short?cycle high?frequency water injection with low injection?shutdown durations can generate periodic pressure fluctuations, reducing cumulative water injection by 80%, while achieves comparable recovery performance to long?cycle injection.This study investigates the influence law of injection parameters on the synergistic enhancement mechanism of imbibitiondisplacement during water flooding in tight oil reservoirs with mixed wettability, providing a theoretical basis for optimizing injection strategies.

Key words: Tight oil reservoir, Mixed wetting, Imbibition, Fracture?porous media, Injection parameter, Pore scale flow

摘要：

基于Navier?Stokes方程与相场理论耦合方法，构建了含裂缝混合润湿致密油藏孔隙尺度数值模型，研究了不同注入速度、注入方式及注停时间下的渗吸采油过程。结果表明，注入速度与采出程度呈非线性关系，0.01 m/s为最佳注入速度，此时毛细管力与黏滞力动态平衡，裂缝?基质压力传递效率最优，采出程度达峰值；周期性间歇注水方式较恒速注水可节水48%，而采出程度仅降低1.08%，在低油价下经济性更优；较短的注停时间配合高频次注水，可形成周期性压力波动，累计注水量减少80%，可实现与长周期注水相同的采油效果。研究混合润湿致密油藏注水开采过程中注入参数对渗吸?驱替协同增效机制的影响规律，为优化注入方式提供了理论依据。
