摘要：

在对辽河坳陷西部凹陷西斜坡潜山油气藏的成藏条件进行解剖基础上，重点开展了古潜山油气运移条件的研究，认为西斜坡古潜山油气藏的油气来源有4种运移路径，论述了不同运移路径的特点，并讨论了影响油气运移的主要因素。在潜山油气藏的多种供油方式中，有效生油岩直接覆盖潜山的多向供油方式最为有利，这种供油方式与规模较大的潜山相配置可以形成大型的潜山油气藏；其次为潜山与有效生油岩通过不整合面或断面接触的单向供油方式，这种供油方式也能形成比较富集的潜山油气藏。这一认识对西斜坡乃至辽河坳陷潜山油气藏的勘探都具有一定的指导意义。

Abstract:

Based on the analysis of accumulation conditions of buried-hill reservoirs in the west slope of west sag in Liaohe depression, this thesis emphasizes on the hydrocarbon migration conditions of buried-hill reservoir. The oil in buried-hill reservoir of the west slope has four types of migration paths.Different migration paths have different characteristics.There are many ways for oil to buried hill, but the most effective way is to migrate oil directly from above or lateral contacted source rocks, resulting in the formation of big buried-hill reservoirs.Oil accumulation by unconformity or fault also can form buried-hill reservoirs rich in oil and gas.These research results can make buried-hill exploration more effective in the west slope, or even in whole Liaohe depression.

Key words: buried hill, migration path, migration direction, Liaohe depression
