摘要

注水开发后期，含水率急剧升高导致水驱油藏开发效果变差，聚合物颗粒分散体系的非均匀分布、增黏等行为能够使占据大孔道流动空间的水相流动能力降低，缓解低效、无效水循环。目前，关于聚合物颗粒分散相驱油的研究主要以室内实验模拟为主，分析聚合物颗粒运移规律；而描述聚合物颗粒分散相驱油过程中油水流动规律及相对渗透率曲线的研究较少。首先，分析聚合物颗粒在多孔介质中的非均匀分布现象，引入生物流体力学中红细胞树状叉体积分数分布理论，建立考虑聚合物颗粒相分离机制影响的体系黏度表征方法；其次，基于分形理论与渗流理论，建立聚合物颗粒分散相驱油的相对渗透率模型，通过与室内岩心驱替实验结果对比发现，验证模型准确性，并分析各因素对聚合物颗粒分散相驱油的相对渗透率影响。该研究对聚合物颗粒分散相驱油的开发效果评价具有重要意义。

Abstract

In the later stage of water injection development, the rapid increase in water content significantly degrades the development performance of water drive reservoirs. The non-uniform distribution and viscosity enhancement of polymer particle dispersed systems effectively reduce the water phase flow capacity that occupies the flow space of large pores, thereby mitigating inefficient and ineffective water circulation. Currently, studies on polymer particle dispersed phase for oil displacement are primarily based on laboratory simulations, focusing on the migration behavior of polymer particles. However, limited research has been conducted on the oil-water flow dynamics and relative permeability curves during the oil displacement process of polymer particle dispersed phase. This study first analyzed the non-uniform distribution of polymer particles in porous media and introduced the red blood cell dendritic volume fraction distribution theory from biological fluid dynamics. A viscosity characterization method was established, considering the effects of the polymer particle phase separation mechanism. Subsequently, a relative permeability model of polymer particle dispersed phase for oil displacement was developed based on fractal and percolation theories. The accuracy of the model was validated through comparisons with laboratory core displacement experiments, and the effects of various factors on the relative permeability of polymer particle dispersed phase for oil displacement were analyzed. This research holds significant value for assessing the development performance of polymer particle dispersed phase for oil displacement.

Key words： high-water content oil reservoir; viscosity characterization; fractal theory; relative permeability curve; polymer particle dispersed phase
