摘　　要：结合精细沉积微相研究成果,按照储层相控随机建模的思路和方法,建立了濮城油田沙一段储层非均质性模型。模型预测结果表征了储层的空间非均质性特征,表明了不同的沉积相区其储层性质和特征有明显差别。与非相控随机建模方法预测模型对比分析表明:相控下的随机储层非均质性模型比较符合储层发育规律和非均质性的变化规律,可信度高,为该区制定和调整开发方案提供了重要的地质信息。通过研究发现,相控非均质性为油藏储层非均质性研究提供了非常有用的新方法。Based on the study result of fine sedimentary microfacies interpretation and according to the principle and method of reservoir stochastic modeling controlled by facies, a heterogeneous model on the Es1 Reservoir of Pucheng Oilfield was established. The characteristics of reservoir spatial heterogeneity were characterized by using the result of model prediction, it showed that there was an obvious difference on reservoir characteristics in different sedimentary facies. Compared with stochastic modeling not controlled by facies, the stochastic model controlled by facies was in line with the reservoir development law and the changes of heterogeneity. It provided an important geological basis for the formulation and adjustment of development programs. The study shows that the heterogeneity model controlled by facies provides a very useful method for the reservoir heterogeneity research.
