摘　　要：提出了基于砂控地质建模和Monte Carlo模拟相结合的地质储量评价方法。通过分析影响储层体积、孔隙度、流体界面、含烃饱和度以及体积系数等储量计算参数不确定性的地质成因,对各参数的不确定性进行评价并给出可能存在的变化范围;在地质建模中体现储量计算参数的不确定性变化;基于地质模型并结合Monte Carlo模拟方法进行地质储量评价。利用本文方法进行储量评价,其结果更客观。For OIIP evaluation, a method is developed based on geological sand control modeling and Monte Carlo simulation. The uncertainties of reserves calculation parameters, such as reservoir volume, porosity, fluid interface, hydrocarbon saturation and volume factor, are evaluated and given a possible variation range respectively, by analyzing their geological origins. The uncertainty variations of reserves calculation parameters are represented in geological modeling, and the OIIP evaluation is made by a combination of geological models with Monte Carlo simulations. The method application can result in more objective OIIP evaluation.
