摘要
顺北断控裂缝型油藏非均质性强,油水运动规律复杂,传统均质模型难以准确表征相对渗透率,提出模块化裂缝网络物理模拟方法。基于天然碳酸盐岩储集层裂缝结构特征,设计不同裂缝复杂程度的天然碳酸盐岩模块物理裂缝模型,开展油水驱替实验,获取不同结构裂缝模型的驱替参数,计算油水两相相对渗透率,建立相渗图版,并根据顺北裂缝型储集层生产井生产情况对油水两相相对渗透率曲线分析验证,掌握油藏动态变化规律。
The fault-controlled fractured reservoirs in the Shunbei oilfield are characterized by strong heterogeneity and complex oil-water movement patterns,making traditional homogeneous models fail to accurately characterize relative permeability.This study proposes a physical simulation method based on modular fracture networks.Regarding the characteristics of natural fractures in carbonate reservoirs,corresponding modular fracture network physical models with varying fracture complexity are designed,and the oil-water displacement ex-periments are conducted to obtain displacement parameters for different fracture models.On this basis,oil/water relative permeabilities are calculated,and the relative permeability charts are plotted.The obtained oil/water relative permeability curves are analyzed and validated using actual production data of wells in the fractured reservoirs to understand the variations of reservoir performance in the Shunbei oil-field.
