摘　　要：总结济阳坳陷各凹陷地温场和地压场的平面和剖面特征以及二者的耦合特征 ,分析不同的地温 地压场特征与油气分布的关系。认为东营凹陷和沾化凹陷具有超压型复式温度 压力系统特征 ,惠民凹陷具有低压型复式温度 压力系统特征。不同的温度 压力系统使得油气藏在各凹陷的形成与分布特征也不同。图 5参The lateral and vertical characteristics of geotem perature and geopressure fields and their coupling characteristics in the Jiyang Depression were summarized. And the relationship between geothermal geopressure fields and hydrocarbon distribution was also analyzed. The study shows that the Dongying Sag and Zhanhua Sag have the characteristics of overpressure T P system, while the Huimin Sag shows sub pressure T P system. Different T P systems controlled the formation and distribution of oil reservoirs in different sags.
