摘要:渤海湾盆地是目前我国已发现石油備量最多的大型油气盆地,它有三个大的油气富集带:西部的冀中坳陷带、中部
的黄骅一临清坳陷带和东部的济阳一渤中ー辽河坳陷带。通过大量勘探实例和储量增长规律研究,剖析各个油气富集带与
地质特征的关系,认为渤海湾盆地资源潜力与勘探对策是:海域的储量探明程度仅为29.7%,是下步储量增长的重要潜力
区;陆上以寻找构造+岩性的复合隐蔽油气藏为勘探重点,针对不同层系采取不同勘探策略,浅层以重新部署三维地震和
老资料处理发现新的含油区带,中层开展老井复查、实行液动勘探发现新层新块,深层开展有效储层研究、寻找碳酸盐岩
油气藏。随着勘探程度的不断深入,渤海湾盆地的储量将会出现新一轮增长高峰。

Abstract: Bohai Bay is currently a large-scale petroliferous basin with the largest petroleum reserves discovered
so far in China. It harbors three large hydrocarbon-enriched zones: the Jizhong depression in the west, th
Huanghua-linging depression in the central, and the Jiyang-bozhong-liaohe depression in the east. Based on
studies of numerous exploration cases and reserves growth pattern and analysis of relationship between these
plays and their geological features, this paper estimates the potential of reserves in Bohai Bay basin and presents
corresponding exploration strategies. The of shore part of the basin has a ration of proved reserves to 0O[P as low
as 29.7%, therefore shall be regarded as the important future target for reserve growth; while for the onshore
part, exploration shall aim at subtle structural-lithological combination reservoirs with different strategies for dif-
ferent series of strata. In the shallow part, new 3-D seismic acquisition and reprocessing of old seismic data are to
be performed to discover new plays; in the middle part, review of old wells and progressive exploration and deve
lopment will be carried out to define new targets; while in the deep part, detailed reservoir study will be per-
formed to look for carbonate reservoirs. By doing this,, it is certain that the Bohai Bay basin will see a new run of
reserves growth in the near future
