摘要：

成藏动力系统可以按封存仓或排液组合来划分。渤海湾盆地内按排液组合可分为6个成藏动力系统,但在各个凹陷分布不一;莺歌海盆地内按封存仓可分成3个成藏动力系统。按不同原则对成藏动力系统有不同的分类方案:据流体压力状态可分为常压型、超压型和低压型;据油源条件可分为它源型、自源型和混源型;据封闭条件可分为开放型、封闭型和半封闭型。每个成藏动力系统自成统一的压力系统,成为相对独立的油气运移聚集单元,油气以在本系统内运移聚集为主,沿大断裂和流体底辟周期流动是油气跨系统运移的基本模式,因此,与之伴生的构造带有利于形成多套成藏动力系统含油的复式油气聚集带。

Abstract:

According to abnormal pressure fluid compartments or expulsion fluid assemblages,a basin can be divided into many accumulating dynamic systems.There are 6 accumulating dynamic systems in Bohai Bay Basin by expulsion expulsion fluid assemblages and 3 accumulating dynamic systems in Yinggehai Basin by abnormal pressured compartrment.The classification of accumulating systems is various according to different criteria,that is:normal pressure,overpressure and low pressure by distribution of fluid pressure systems;external source,internal source and compound source systems by oil source;and open,closed and semi closed systems by sealing condition.Hydrocarbon migrates mainly within particular dynamic systems,and the basic migration model of cross systems is periodic migration along large faults and fluid diapirs.The structural zones associated with large faults and fluid diapirs are favorable to form complex oil and gas zones of multiple accumulating dynamic systems.
