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。
The Bohai Bay region in eastern China is rich in oil and gas resources. Due to the thick oil-bearing rocks, diverse reservoirs and trap types, it has become a large oil region in China. Due to the many frequent horizontal movements in the geological history and the differences between the movements, the tectonic pattern of the distribution of the dimples and the projections is caused. Now people are more energy in the depression to find oil, I predict the region will appear more and more important role of convex, it is possible to find more oil and gas fields, the region should be looking for bumps in one of the new areas of oil, Taking the exploration of the Chenjiazhuang uplift in Jiyang Depression as an example, the geological conditions of the oil bump are pointed out, the causes of the bump are classified, and the mechanism of the bump hydrocarbon accumulation is explained. Reservoirs and basement reservoirs, in particular, should pay attention to find the body reservoir.
