Abstract:

致密砂岩中的油气成藏是油气地质学领域内的前沿问题。如何将影响油气运移成藏的流体动力、成岩事件与油气成藏期次研究相结合,以准确确定油气的成藏机理,仍是目前研究中的薄弱环节。首先论证了青山口组烃源岩的热演化程度和生烃潜力;恢复了最大埋深时期(古近纪末)泥岩的过剩压力,探讨了流体动力作用下的油气运移、成藏特点;立足成岩作用与成藏事件的紧密联系,根据次生包裹体均一温度、自生碳酸盐矿物的碳、氧同位素资料分析了成藏期次;最后综合石油地质概念模式和储层内流体活动的记录,建立了油气运移、成藏的模式。研究认为,青山口组烃源岩经历了较高的热演化程度(Ro达1.0%~1.2%),古近纪时其中的过剩压力可达6~11MPa,为油气运移提供了充足动力,砂岩储层内曾于明水期(K2m)内发生过含烃流体的两期注入。提出了古近纪前、后的“跷跷板”式成藏模式,即明水期―古近纪油气主要由源区向西南方向运移,而新近纪后的油气运移主要靠浮力驱动,但因储层已致密化,难以形成较高的连续油柱,油、水的分异程度低。
