摘要
针对低渗透油田五点法注水开发井网，采用数值模拟方法，研究了整体压裂改造中水力裂缝方位及参数对采收率的影响。提出了把油藏与裂缝按一个系统建立数学模型的求解方法，并通过实例计算和文献结果对比，验证了这种方法的可行性。
In view of five-spot water-injection pattern in low permeability reservoits, this paper studies the effect of fracture parameters and orientation in an integral fracturing on oil recov-ery by using reservoir simulation. With this simulation, we introduce a model-building andsolving method which incorporates matrix and fracture into one system, By calculation of oilfield examples and in comparison with the results from literatures , this model has beenproven to be effective.
