【摘要】：为了认清油气藏形成过程,在对油气藏概念、运移阶段及运移动力进行深入分析的基础上,指出了浮力是二次运移和聚集成藏最主要的永恒的动力。油气藏从最初形成之后普遍受到构造运动的影响发生破坏及再运移,含油圈闭中油气溢(逸)散和注入经常出现,现在勘探找到的油气藏大多数都不是原生油气藏,受构造运动的影响油气藏都具有晚期定型的特点,所以并不是圈闭形成越早越好,只要盆地有生烃能力,所有圈闭都存在形成油气藏的机会,最终能否成藏要看运移通道及保存等条件。油气从生成到聚集成藏是一个随着构造运动变化的漫长过程,油藏原始含油气饱和度是衡量油气藏变化及定型的重要指标。
[Abstract]:In order to understand the formation process of oil and gas reservoirs, based on the in-depth analysis of the concept, migration stage and migration dynamics of oil and gas reservoirs, it is pointed out that buoyancy is the most important eternal driving force for secondary migration and accumulation. After the initial formation of oil and gas reservoirs, oil and gas reservoirs are generally destroyed and remigrated by tectonic movement. Oil and gas spills (escape) dispersion and injection often occur in oil-bearing trap, and most of the oil and gas reservoirs found in exploration are not primary oil and gas reservoirs. The oil and gas reservoirs affected by tectonic movement have the characteristics of late stereotyping, so it is not that the sooner the trap is formed, the better, as long as the basin has the ability to generate hydrocarbons, all the traps have the opportunity to form oil and gas reservoirs. Whether the reservoir can be formed or not depends on the migration channel and preservation conditions. The formation of oil and gas from generation to accumulation is a long process with the change of tectonic movement. The original oil and gas saturation of the reservoir is an important index to measure the change and stereotyping of oil and gas reservoirs.
