非均质油藏水驱前缘动态监测用物理模型优选研究

Research on Optimization of Physical Model for Dynamic Monitoring of Leading Edge of Water Drive in Heterogeneous Reservoirs

通过对几种典型的水驱前缘动态监测物理模型(柱状岩芯、仿真孔隙模型、真实砂岩微观模型、平板填砂模型、平板胶结模型)进行对比研究,发现平板胶结模型不仅可以模拟平面及纵向非均质性,对水驱油过程实施适度可视化,还能满足压力、电阻检测需要,是非均质油藏水驱前缘动态监测合适的物理模型。

Through comparative study of several typical physical models for dynamic monitoring of leading edge of water drive(columnar core,simulated pore model,real sandstone microscopic model,flat sand filling model,and flat cementing model),it is found that the flat cementing model can not only simulate plane and longitudinal heterogeneity,implement moderate visualization of water drive oil process,but also meet the needs of pressure and resistance detection,and is a suitable physical model for dynamic monitoring of leading edge of water drive in heterogeneous reservoirs.
