经过近50年勘探开发，以济阳拗陷为代表的中国东部成熟探区已达到中等—高勘探程度。在前人研究成果和胜利油田勘探实践的基础上，指出以下几个亟待解决的制约精细勘探的地质问题：高精度层序地层分析、油气成藏期关键地质要素恢复、油气输导体系精细刻画及油气成藏定量评价，对并它们的研究进展进行了综述；层序地层学研究由传统向高精度方向推进、关键地质要素恢复的研究由现今向关键成藏期发展、油气输导体系刻画由二维平面向三维立体突破、油气成藏研究由定性评价向定量表征提高；同时，还提出了各关键地质问题的研究方法和发展方向；最后，指出成藏过程及其主控因素的定量研究既是油藏研究的关键所在，也是今后勘探的必然要求。

The prospect areas including Jiyang Depression in east China has stepped into a relatively mature stage on the whole after about fifty years′exploration and development. Some problems crying out for solutions in the sphere of intensive geological evaluation of the mature exploration areas,which includes the analysis of high resolution sequence stratigraphy,the restoration of key geological elements at the crucial moment of petroleum accumulation,the accurate interpretation of petroleum migration pathway system,and the quantitative characterization of petroleum accumulation process,are pointed out and systematically reviewed on the basis of the previous researches and exploration practices in Shengli Oilfield. We find that sequence stratigraphy researches have developed from traditional pattern to high resolution model;researches on key geological element restoration have developed from state at the present time to the condition at the crucial moment of petroleum accumulation;interpretation of petroleum from two-dimensional surface to three-dimensional body,and petroleum accumulation researches have developed from qualitative analysis to quantitative evaluation. Finally,the authors put forward that the quantitative study of petroleum accumulation process is the development trend of both theoretical analysis and exploration practice.
