摘要
干酪根产烃率是盆地模拟计算油气资源的一项非常重要的参数,以往采用岩石样品热模拟建立产烃率图解的方法对于高过成熟烃源岩有一定的局限。根据元素守恒相关理论,建立了一种通过H/C原子比变化来估算烃源岩产烃率的方法,作为热模拟实验方法的补充。与模拟实验相比,该方法简单易行,结果较为可靠。将这一方法应用到塔里木盆地台盆区寒武系烃源岩,估算了这套烃源岩的晚期生气潜力,取得了一定的成果。
In basin modeling,hydrocarbon yield is one of the most important parameters.In past evaluation,it was generally obtained from simulation experiments,which would meet some troubles for high-mature or over-mature source rocks.Based on element conservation theories,an alternate method is introduced,which could serve as an additional method for simulation experiments and overcome the shortages mentioned above.Taking example for Cambrian source rocks in the Tarim Basin,the gas potential of typeⅡkerogen was evaluated.Compared with other methods,it is not only simple,but also reliable.By applying to later gas potential evaluation,this method is recognized in practice.
