摘　　要：大部分国内油田和海外开发油田已经进入高含水期，探索高含水油田剩余油分布规律对油田高效、可持续开发具有重大意义。在大量文献调研的基础上，综合国内外微观和宏观剩余油分布研究方法、主控因素及分布规律后认为，采取分层次、分规模剩余油分布研究策略有利于明确剩余油的优势潜力及挖潜技术方向，综合多学科定量化表征剩余油分布有利于降低预测的不确定性，为更精准表征剩余油需大力发展地震、测井及大型精细化数值模拟技术，微观上需建立更完善的仿真模型及更先进的饱和度测量方法，宏观上需加强天然能量驱动油藏及非常规油藏剩余油分布规律研究，完善以多层状砂岩油藏注水开发为主导的剩余油分布模式，以改善高含水油田开发效果。Most of the developed oilfields in China and overseas have entered into high-water-cut stage, so the ex- ploration of the distribution laws of the remained oil possesses very important significances for the high-efficiency and sustainable development of the oilfields. Based on the extensive literature investigation, with the help of the in- tegration of the studying methods of the micro-and-macro remained oil distributions at home and abroad, major con- trolling factors and distribution laws, the multi-level and multi-scale research strategies are thought to be beneficial to make clear of the advantage potentials and tapping technologies ; integrating multi-discipline methods to quantati- tively characterize the distributions of the remained oil can reduce the prediction uncertainty. For more precise characterization, it is required that the great advances of seismic, logging and large-scale fine numerical simulating techniques： in the micro-scale, it is needed to establish more perfect realistic simulating model and more advanced saturation measuring method ; while in the macro-scale, more attention should be paid to the studies of the remained oil distribution laws in both natural energy driven and unconventional oil reservoirs, so as to perfect the distribution pattern of the remained oil in muhi-layer sandstone water-flooded reservoir, finally to improve the development effects of those high -water-cut oilfields.
