盆地模拟技术在禹城地区的应用

盆地模拟能为地质家提供一个快速、定量、综合的研究手段,揭示盆地油气分布规律,为勘探决策提供直接或间接的依据.禹城洼陷是临清坳陷东部最具潜力生油洼陷,其油气勘探至今仍未获得有效突破,研究认为主要原因之一是对油气运移聚集规律认识不足.应用IES盆地模拟技术,恢复了禹城地区的地史和热史,模拟了沙三下和沙四上烃源岩的生排烃史和油气运移聚集史,指出了禹城洼陷油气勘探的有利区带.

On the Application of Basin Numerical Simulation I Yucheng Region

The Basin Numerical Simulation can provide for geologician a fleet, fixed amount and comprehensive research means, announce to the distribution rule of hydrocarbon, and offer direct or indirect basis for the prospect decision. The Yucheng subsag is the most potential one that creates hydrocarbon in Linqing depression, but its oil prospect hasn't effectively been broken yet. We think that one of the main reasons is that it's lack of the knowledge of hydrocarbon migration and accumulation. This paper restore the structural history, the sedimentary history and the thermal history of Yucheng region by using IES Basin Numerical Simulation, simulate the history that hydrocarbon produced , ejected , migrated and accumulated of source rocks in the next segment of Es3 and the top segment of Es4, and point out the beneficial area of hydrocarbon prospect in Yucheng subsag.
