摘　　要：南黄海盆地油气勘探至今53年,亟待突破工业油气发现关。关键的难题涉及中古生界各层系勘探前景及选区评价分析,厘清盆地中古生界分布及构成、井震油气地质特征和勘探前景,前陆期三叠系海相储层体系与侏罗系富生烃凹陷等等。公认下扬子上、下古生界发育多套优质烃源岩,南黄海盆地中部隆起古生界历经多期复杂构造演化,被认为具有重要前景。它的油气来源、成藏与保存值得深究,是位于深部还是运移而来,可能与四川盆地具有区别。指出关键需要实施多区带多领域多角度全方位勘探。During the past 52 years,no commercial oil and gas have been discovered in the Southern Yellow Sea Basin.As far as the Meso-Paleozoic is concerned,the key problems remain with the evaluation and selection of the exploration targets,the delineation of the distribution of the Paleozoic,the clarification of the distribution and formation of Meso-Paleozoic basins,and the understanding of characteristics of well-to-seismic geology.As to the Mesozoic,it needs to understand more about the foreland period of the Triassic marine reservoir system and the Jurassic hydrocarbon-rich depression.It is widely believed that there are several sets of high quality source rocks in the upper and lower Paleozoic of the Lower Yangtze Region.On the central uplift of the South Yellow Sea Basin,the Paleozoic is believed a significant prospect,where multiphase of complex tectonic movement prevailed.It is worthy to make further study on the sources of oil and gas.It is probably that oil and gas are coming from the deeper part,which is quite different with the cases in the Sichuan basin.Therefore,it is critical to carry out comprehensive exploration from the viewpoint of multiple zones and multiple angles.
