摘要
盆地整体上升遭受剥蚀是盆地演化过程中的重要演化阶段,对构造格局、沉积演化及油气成藏都具有重要的影响。通过对苏北盆地高邮凹陷始新世末期三垛运动的分析,认为三垛运动强度大,具有抑制烃源岩热演化、改造储层及促进成藏等作用,对全面系统地认识高邮凹陷的石油地质条件具指导作用。
The rising and erosion of the whole basin was an important stage of basin evolution,and it had important effect on the tectonic pattern,sedimentary evolution,and hydrocarbon accumulation.By analyzing the Sanduo movement in the late Eocene of Gaoyou Sag of Subei Basin,it is considered that Sanduo movement had big strength,which has played a very important role in restraining thermal evolution of hydrocarbon source rocks,reservoirs reconstruction and promoting hydrocarbon accumulation.This analysis is a guide to understand systematically the petroleum geologic conditions of Gaoyou Sag.
