利用随机建模技术建立了储层地质模型：应用高分辨率层序地层方法对地层进行了精细的划分,搭建了精细的构造模型；在此基础上,以二维沉积微相平面图为约束,应用截断高斯法对沉积相进行了模拟,该法能够反映清晰的相边界,适合末端扇沉积体系,在多个实现中优选出与真实情况相符的模型；同时对比了相控和非相控条件下孔渗特征,结果表明在相控条件下储层物性参数非均质性能更好的体现,更有效地刻画储层非均质性,确定井间不确定参数分布。为了检测模型的准确性,应用储量拟合和生产动态拟合对模型进行检验,2项检验指标显示出较好的拟合效果,所建立的模型真实可靠,可以为下一步的数值模拟提供真实可靠的地质三维体。

Stochastic modeling was used to built a reservoir model which can depict effectively reservoir heterogeneity,study the uncertainty parameters distribution between wells,and reflect stochastic process in reservoir evaluation.Truncated Gaussian simulation was applied in sedimentary facies modeling,this method can reflect the facies boundary clearly,and it is suitable for terminal fan sedimentary system;Comparison of porosity and permeability feature between facies-controlled and non-facies-controlled modelings illustrated that facies-controlled modeling can better reflect reservoir physical parameter heterogeneity.Reserves fitting and production performance fitting were used to test model accuracy.The model was found to be true and reliable, and can provide a three-dimensional geologic model for subsequent numerical simulation.
