Abstract: With its abundant hydrocarbon resources, thick source rocks and multiple types of reservoirs and traps, the Bohai Bay area has become a large oil region in China. The different nature of frequent horizontal motion from elevation and subsidence in the geologic past created a tectonic framework with depression and uplift alternately disposed. So far, we have paid more attention to the depressions in guest of oil, but, in the opinion of the author, the margin of the depressions where more oil and gas pools may be found will become more and more important and should be made a new objective for oil exploration in the region. The margin of the Jiyang depression at Chenjiazhuang is cited as an example, giving full description of its favourable geological conditions, difference of origin and the mechanism of its oil and gas aecumulation. It is proposed that more effort should be directed toward the search of oil pools in the drape folds, wedge-outs and basement, particularly in the wedge-outs.

摘要： 中国东部渤海湾地区,油气资源十分丰富,由于生油岩厚,储集层多种多样,圈闭类型,已成为中国的大油区。由于地质历史中多次频繁的水平运动和升降运动的差异性,造成了凹陷与凸起相间分布的构造格局。现在人们以更多的精力在凹陷中找油,笔者预测本区凸起将出现越来越重要的作用,有可能发现更多的油气田,本区凸起应该是找油的新领域之一,从济阳坳陷陈家庄凸起的勘探为例,指出凸起含油的地质条件,对凸起的成因作了分类,阐述了凸起油气聚集的机理,指出应重视寻找披覆油藏、楔状体油藏以及基底油藏,特别是应注意寻找状体油藏。
