摘要： 建立了考虑源(汇) 影响的含有不渗透区域复杂边界条件下各向异性油藏稳定渗流的数学模型。利用边界元法求解数学模型, 获得了地层中任意一点的压力公式。在此基础上, 提出了流线场的生成方法, 绘制了考虑各向异性、复杂边界和不渗透区域影响的流线分布图, 并分析了流线分布的特征。研究表明, 渗流场的各向异性和不渗透区域的存在都对流线分布存在较大的影响。利用该方法产生的流线分布图能够较为直观地反映出油藏流体在注采井间的运动轨迹, 为优化井网和注入方案提供重要依据。

Abstract: The steady-state flow mathematical model for anisotropic reservoir with impermeable barrier is developed. The pressure equation of arbitrary point of formation is obtained by using boundary element method (BEM) to the model solution, and streamline field generating technique is then proposed, including the streamline distribution diagram with anisotropic flow field, complex boundary and impermeable area effects as well as streamline feature analysis. The study shows that the streamline distribution is sensitive to the existing anisotropic flow field and impermeable area. Hence, the plotted diagram could more visually reflect the flowing tracks of reservoir fluid between injector and producer, providing an important basis for optimization of well pattern and injection strategy.

Key words: boundary element method, streamline, anisotropy, mathematical model, distribution, steady-state flow
