【摘要】：渤海湾盆地渤海海域已发现大中型油田31个,且有9个是亿吨级油田。结合前人认识,总结这31个大中型油田的成藏模式和规律,对渤海海域大中型油田的持续发现,确保储量增长具有重要的指导作用。研究表明,渤海海域大中型油田具有凸起披覆型、走滑反转型、凹中隆披覆型、陡坡断块型和缓坡断鼻型等5种主要成藏模式,且具有独特的成藏规律:紧邻(潜在)富烃凹陷是形成大中型油田的必要条件;优越储盖组合是形成大中型油田的保障;活动断裂带特别是郯庐断裂带是大中型油田形成的有利聚集区带;晚期成藏中"时-空-源"成藏条件的耦合是形成大中型油田的关键。
[Abstract]:31 large and medium-sized oilfields have been found in the Bohai sea area of the Bohai Bay Basin, and 9 are billions of ton oil fields. In combination with the previous knowledge, the reservoir forming patterns and rules of these 31 large and medium-sized oilfields are summarized, which have important guidance for the continuous discovery of large and medium-sized oilfields in Bohai sea area and the increase of reserves. The research shows that the large and medium oil fields in the Bohai sea area have a large scale. 5 major reservoir forming modes, such as protruding and drape type, strike slip reverse transformation, concave middle uplift type, steep slope fault block type and gentle slope broken nose type, are the necessary conditions for the formation of large and medium oil fields; the superior reservoir and cover combination is the guarantee for the formation of large and medium oil fields, and the active fault zone is especially the Tanlu fault zone. It is a favorable accumulation zone formed by large and medium-sized oil fields. The coupling of "time air source" reservoir forming conditions in late hydrocarbon accumulation is the key to the formation of large and medium-sized oil fields.
