摘　　要：根据能量分析的观点,将与油气运移密切相关的诸因素所构成的因果链中最为重要的上覆负荷与压实、流体压力和流体势作为一个不可分割的系统,可以避免单独考虑其中某一个因素所带来的不足。应用此系统探讨了渤中地区油气运移的开始深度和时间以及二次运移的方向和可能的聚集场所,认为该地区油气初次运移的深度约为2750～3250m,排油期从东营组沉积时期到明化镇组沉积时期;二次运移主要指向周边凸起,并聚集于各凸起与凹陷相接的斜坡带上。From the viewpoint of energy analysis, the most important factors relative to the migration of oil and gas, which are compaction, fluid pressure and potential, have been proposed as a united system. With this system, the depth and time of primary migration and the direction and possible accumulation places of second migration of oil and gas in Bozhong area have been concluded. The depth of the drainage of hydrocarbons is about 2750～3250m whereas the time is from depositional age of the Dongying formation to that of the Minghuazhen formation; The directions of second migration of hydrocarbons are mainly to the surrounding arch regions, and these hydrocarbons may be accumulated in the slope parts connecting arch region with depression.
