下寺湾油田长8段储层相控建模研究

Study of Facies Control Reservoir Modeling for the Chang 8 Member in the Xiasiwan Oilfield

运用Petrel储层建模软件,对下寺湾油田长8段砂组进行储层相控建模研究。首先利用序贯指示模拟方法建立能够表征储层较大规模非均质性的沉积微相模型;在沉积微相模型建立之后,采取相控物性参数建模方法,分小层分微相统计各种物性参数分布特征;然后利用序贯高斯模拟方法分别进行模拟,建立了研究区的孔隙度模型、渗透率模型和含油饱和度模型。结果证明按此方法建立的模型效果较好,客观反映了地质实际,为该区下一步滚动勘探开发提供了地质依据。

This paper deals with facies control reservoir modeling in the Chang 8 Member in the Xiasiwan Oilfield with the Petrel sol＇ware. At first, the 3D sedimentary microfacies model is established by means of sequential indication simulation, then, porosity model, permeability model and oil saturation model are built under the control of microfacies model by means of sequential Gauss simulation. The results indicate that this modeling method is effective which can provide geological basis for following exploration and development.
