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.

Abstract: 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.

Key words: fracturing, hydraulic fracture, recovery efficiency, numerical simulation, low permeability pools
