摘要
江苏油田小断块油藏剩余油成因的研究方法主要有地质综合分析法、精细油藏数值模拟法、油藏工程动态综合分析法、剩余油监测法。剩余油的成因有4种,即储层非均质性(如沉积微相)的控制、构造(如断层)的控制、注采系统完善程度的影响、复合因素的影响。根据不同的油藏类型、储层特征及开发条件下形成的剩余油的不同,实施不同的调整挖潜对策。
The origins of remaining oil in small fault-block reservoirs ,Jiangsu oilfield, are studied by several methods ,such as comprehensive geological analysis ,refined numerical simulation of reservoir,integrated dynamic analysis of reservoir engineering and remaining oil monitoring.Four origins of remaining oil are revealed,in~ cluding reservoir heterogeneity （e.g.sedimentary microfacies） controls, structure （e.g.fauh） processes, effects of the injection-production system adaptability,and effects of complex factors.For different reservoir characteristics and different development conditions,different adjustive measures can be taken to tap production potential of remaining oil.
