摘要
渤海海域埕岛油田新近系油气资源丰富,具有多凹陷多层段供烃,多种储盖组合,多种油气藏类型,多种油气输导通道等成藏基本条件。油源断层的存在是新近系油气成藏的前提,断层活动的期次和规模控制油气分布的层段、断层的侧向封闭性控制着油气的聚集,构造对新近系油气聚集具有宏观控制作用,岩性对新近系油气聚集具有微观控制作用。
Oil and gas resources are rich in Neogene of Chengdao oilfield, Bohai Sea. There are many favorable conditions for reservoir to form, including sags and layers for oil supply, a variety of reservoir- cap combinations, multi-reservoir types, and multi-pathways, etc. The existence of fault is the requirement for Neogene reservoir to form. The period and scale of fault activities control the oil and gas layers. The lateral sealing condition of faults controls hydrocarbon accumulation. Tectonic and lithology are important factors to control reservoir formation.
