摘要
利用盆地模拟方法对鄂尔多斯地区古生界的生烃史和排烃史进行了模拟研究．结果表明，该区上古生界烃源岩处于高成熟阶段，下古生界烃源岩已进入过成熟阶段，这两套烃源岩在地史上都出现过两次生、排烃高峰，上古生界的生、排烃量远大于下古生界．这些结果可用于评价该区的油气远景和认识油气藏的形成过程。
The generation and expulsion histories of Paleozoic source rock in Ordos region is studied by using basin modelling method. The evolution histories, main generation stages, expulsion stages. and generation and expulsion amount of upper and lower Paleozoic source rocks were presented. The study results are important to evaluate the oil and gas prospects and understand accumulation history in the region.
