Abstract:
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.
Key words: dynamics of pool formation, secondary petroleum pool, tertiary migration, thread of thought
