摘要
基于生储盖层条件分析,采用盆地模拟技术对开鲁盆地陆西凹陷的埋藏史、热史、生烃史、排烃史、运移聚集史进行模拟,得到不同时期油气在纵向上不同地层中的分布情况。再结合流体势分析划分油气运聚单元,从而得到油气在横向上的分布,最终指出有利的油气聚集区,为勘探开发指明方向。研究结果表明:九佛堂组上段和下段在白垩纪—现今达到排烃高峰期,沙海组和阜新组目前才开始大量排烃。陆西凹陷油气勘探潜力较大。五十家子庙洼陷、包日温都断裂构造带和马家铺高垒带是该区最有利勘探区带,马北斜坡带是较有利的油气勘探区。该模拟技术是评价构造单元资源量、优选有利探区、降低勘探风险的一种有效方法。
Based on the study of conditions of source rock-reservoir-seal, this article utilizes the basin modeling method to simulate the burial history, thermal history, hydrocarbon generation history, hydrocarbon expulsion history, hydrocarbon migration-accumulation history in Luxi Depression of Kailu Basin, the vertical hydrocarbon distribution is got in different reservoirs and different periods. We divided the petroleum migration and accumulation units according to the fluid potential, which gained the hydrovarbon distribution in lateral. The study results show that the Lower and Upper members of Jiufutang Formation reached the hydrocarbon expulsion peak from Cretaceous to nowadays. Shahai and Fuxin Formations began to expel the hydrocarbon largely in recent years. The Wushijiazimiao secondary depression, Baoriwendu faulted structure zone, Majiapu high rampart belt are the most favorable exploration areas in the region. Mabel slope zone is an more favorable exploration area. The modeling technology is an effective method to evaluate the resource volume of structure units, to optimize the favorable area and to decrease the exploration risk.
