摘要: 在详细分析临南洼陷油气运移的动力系统、输导条件、运移方向以及运移时期的基础上,对临南洼陷内油气运移特征进行了系统研究。研究结果表明:(1) 临南洼陷油气运移系统具有明显的分层特征,在3000m以上地层为正常压力系统,3000m以下地层为混合压力系统,浮力和异常压力构成了临南洼陷内油气运移的主要动力;(2) 近东西走向的断层和相互连通的砂体共同组成了油气由洼陷中心向边缘运移的通道;(3) 油气由洼陷中心向边缘运移共有4个优势运移方向;(4) 油气运移时期出现在渐新世东营期。

Abstract: Based on the detailed analysis of dynamic systems,pathway conditions,directions and times of petroleum migration in Linnan Sag,a systematic research on oil migration characteristics in Linnan Sag is made.The results show that:(1) oil migration system in Linnan Sag varies distinctly from formation to formation.Normal pressure system appears in formations above 3000m,while mix pressure system appears below 3000m.And buoyancy and abnormal pressure are the main oil migration dynamics in Linnan Sag;(2) Near east west fault and interconnected sand bodies are the pathways for oil migration from Sag center to margin;(3) Four superior migration directions exist for oil migration from Sag center to margin;(4) Oil migration happened in Oligocene Dongying Period.

Key words: Linnan Sag, hydrocarbon migration, migration agent, passage system, migratory direction, migration time
