基于有限体积法的致密油储层数字岩心中流动与传热研究
Flow and Heat Transfer Study on Reconstructed Digital Core of Tight Oil Reservoir Based on FVM
摘要
Abstract
With Micro-CT scanning and advanced image processing technology,3D digital core presenting real pore structure and pore network modeling are performed on the core sample drilled from the tight oil reservoir of Jimusaer,and the distribution of the volume and equivalent diameter of pores and throats are acquired by statistical analysis.The CFD software named ANSYS FLUENT,based on Finite Volume Method (FVM),is used to simulate the flow and heat transfer in the reconstructed pore space,and the absolute permeability in different directions is calculated.A special flow path in the geometry,Convergent Flow Channel,is observed by the streamlines at micro scale,whose size plays an important role in the absolute permeability.In this paper,Micro-CT scanning technology and CFD software ANSYS FLUENT are combined,which is a approach for research on the complex flow and heat transfer in core sample of tight oil reservoir.关键词
