摘要
对北海盆地镁灰岩统盐岩特征研究后指出,盐岩对该区油气成藏具有重要的影响:一是区域分布的厚层盐岩为南北海盆地大中型气田提供了优质盖层;二是盐岩不仅有利于储集层物性的保持,而且提高了储集层的渗透性;三是盐的构造活动形成了油气运移的通道,同时与盐岩有关的相关构造是盆地重要的圈闭,为油气聚集成藏提供了有利场所。
The study on the Zechstein salt rocks in the North Sea Basin shows that Zechstein salt rocks have significant influence on hydrocarbon accumulation in this area. Firstly, the regional distributing thick salt rocks could provide excellent cap rocks for big-and- middle-sized gas field in the southern North Sea Basin. Secondly, the salt rocks are not only favorable for protection of reservoir po- rosity, but also favorable for permeability improvement. Thirdly, the tectonic activity of salt rocks has created HC migration pathway. In addition, the salt-related structures are important traps in this basin, and can provide favorable conditions for hydrocarbon accumu- lation.
