摘要
对渤海湾盆地第三系火成岩 (侵入岩、喷出岩和火山碎屑岩 )的分布及其油气成藏规律进行了分析。研究结果表明 :①近油源、富油源是火成岩成藏的基本条件。②火成岩储层以构造裂缝为主 ,其形成与盆地内区域性的构造断裂、构造运动和火成岩的多旋回性活动有关 ,浅埋藏、成岩作用弱是火成岩中原生孔隙得以良好保存的重要条件。③火成岩成藏过程中的油气运移、聚集模式可分为同层运聚型、上层运聚型和下层运聚型 3种类型。其中同层运聚型具有良好的成藏条件 ,是渤海湾盆地中最常见的成藏模式。分布在近油源、近断裂带的火成岩具有有利的成藏条件 。
The igneous rock of Tertiary and oil and gas reservoir generated by igneous rock in Bahai Bay basin are studied. The forming conditions of igneous oil and gas reservoir include: ①accessible oil resource and abundant oil resource; ②the good forming and keeping condition of the igneous reservoir; ③the igneous rock nearby the fault in the basin. According to the relationship between the distributed location of the igneous rock and the hydrocarbon resource rock, the model of hydrocarbon migration and accumulation can be divided into three types of the same stratum migration and accumulation, the superstratum migration and accumulation, and the substratum migration accumulation. The same stratum migration and accumulation has the best forming conditions for the igneous oil and gas reservoir, and it is also the most familiar model in Bohai Bay basin.
