摘　　要：在松辽盆地西部斜坡区地下水物理化学特征分析的基础上,采用Basin2盆地模拟程序恢复了研究区地下水演化历史,探讨了地层水动力场演化与油气聚集的关系。研究结果表明,地下水在地质历史时期的运移方向和强度是不断变化的,在压实水阶段西部斜坡区水动力场促进了油气运移,在淋滤水阶段则阻碍了油气运移并使原油稠化,压实水和淋滤水运动碰撞带是油气运聚的有利地区。Based on physical and chemical features analysis of subsurface water in west slope of Songliao Basin,subsurface water evolution history in the region of interest is retrieved with Basin2 basin simulation program, and relationship between formation hydrodynamic field evolution and hydrocarbon accumulation is discussed.Research shows that migration direction and intensity of subsurface water at geologic history age keep changing,hydrodynamic field of west slope promotes hydrocarbon migration at the stage of water compaction while hinders hydrocarbon migration and thickens the crude oil at the stage of leechwater,and compaction water and leechwater collision belt is the favorable belt for hydrocarbon migration and accumulation.
