油气次生成藏动力学

油气次生成藏动力学主要研究从原生油气藏破坏到次生成藏的驱动力及其作用过程,并总结从原生油气藏到次生油气藏的系列成藏模式。油气次生成藏地质作用是基础,油气溢出方式、三次运移的驱动力和流动方式分析是核心,总结系列成藏模式是目的。次生成藏主要有构造、水力和二者的复合3种地质作用。底部溢出的油气以浮力作用为主进行渗流,顶部溢出的油气可以是渗流,也可以是以超压作用为主的涌流。成藏模式包括跨成藏动力系统垂向成藏、成藏动力系统内侧向成藏和垂向成藏3种。

Dynamics of Secondary Petroleum Pool Formation

Dynamics of secondary petroleum pool formation is to study the power and process from primary petroleum pool destroyed to secondary petroleum pool forming,and to sum up the formation models for a series of pools.The base is the geological functions that cause the formation of secondary petroleum pools.The core is the types of spilling from primary pools,the power and flow process of petroleum tertiary migration.The aim is to summarize the formation models of secondary petroleum pools.There are three geological functions including structural stress,water power and the combination of both that form secondary petroleum pools.Oil and gas which spilled from the bottom of the primary pools migrate in the way of seepage flow mainly influenced by floatage.However,the ones which spilled from the top can seep,and also can migrate in the way of inrushing flow caused by overpressure.Formation models of pools contain three kinds: vertical accumulation over the dynamic system of pool formation,lateral accumulation and vertical accumulation in the dynamic system of pool formation.
