华北地区的石油普查勘探,经历了漫长而曲折的道路,在实践中逐渐认识到早第三纪凹陷内油气分布的规律,已发现有十四种类型的油气田,探明××亿吨石油地质储量。

The depressions of paleogene are rich in oil/gas resources and hundrands of oil/gas fields have been discovered. Large oil fields are not only distributed in large depressions but also in small-scale depressions. In some small but rich in oil and gas depressions, the oil reserve can reach 100-150 million ton within a thousand sq.Km. The distributions of oil/gas in depressions are controlled by three key factors of space configulation, growth faults and depositional system of source rocks. The various depressions would contain different oil and gas accumulations due to the changes of the three factors, then formed various types of oil and gas pools.
