钻井过程中钻井液对油气层的损害十分严重,因此弄清钻井液在地层中的流动情况显得尤为重要。本文从钻井液对地层的损害研究入手,对比分析了多孔介质的数学模型,建立了多孔介质/纯流体耦合流动区域可压缩流体的流动特性的物理模型和数学模型,并运用GAMBIT软件和FLUENT软件对多孔介质内可压缩流体的流动特性进行模拟研究。
Drilling fluid during the drilling damage to the hydrocarbon layer is very serious, so to understand the flow of drilling fluid in the formation is particularly important. Based on the study of drilling fluid damage to formation, the mathematical model of porous media is comparatively analyzed. The physical model and mathematical model of flow characteristics of compressible fluid in porous medium / pure fluid coupling flow area are established. By using GAMBIT software and FLUENT software The flow behavior of compressible fluid in porous media was simulated.
