摘　　要：目的探究应用盆地模拟技术在油气运移主要路径上寻找有利的圈闭。方法应用油藏地化和盆地模拟相结合的研究方法,分不同成藏期次对胜北洼陷主要目的层系的油气运聚进行模拟。结果胜北洼陷早、晚主要成藏期均有3条油气运聚的主要路径,但具体方位有所差异。其中早期运聚路径对后期油气运聚影响较大。结论该模拟技术的应用,为研究逆断层发育盆地的油气运移提供了一条新思路,也为油田目标勘探提供了一套快速、行之有效的方法。Aim To find a favourable trap in major migration path of the oil and gas with the application of the simulation technology. Methods With the combination of the reservoir geochemistry and basin simulation technology, in different reservoiring stage simulated the oil-gas migration and accumulate of the main target oil layer in Sheng-bei Depression. Results There are the three main migration path of the oil and gas in the main early and late reservoiring stage in Sheng-bei Depression, but there are difference at the specific direction. Furthermore, the early migration path has more effect on the late stage of the oil and gas migration than the late. Conclusion The application of this technology afford a new idea for researching the hydrocarbon migration in the reverse fault basin ; as well as provide a rapid and effective way for oil objectives exploration.
