储层建模分为确定性建模和随机建模,随机建模既能够模拟油气储层的非均质性也能定量表征油气储层。随机建模是目前油气储层建模的发展方向。油藏数值模拟方法是迄今为止定量地描述在非均质地层中多相流体流动规律的惟一方法,也是定量描述剩余油的重要手段。文中提出了储层随机建模技术与油藏数值模拟方法相结合的建模思路和步骤。
Reservoir modeling is divided into deterministic modeling and stochastic modeling. Stochastic modeling can both simulate the heterogeneity of oil and gas reservoirs and quantitatively characterize oil and gas reservoirs. Stochastic modeling is the development direction of oil and gas reservoir modeling. The reservoir numerical simulation method is by far the only way to quantitatively describe the law of multiphase fluid flow in heterogeneous formations and is also an important means for quantitatively describing remaining oil. In this paper, the modeling ideas and steps of reservoir stochastic modeling and reservoir numerical simulation are proposed.
