Present state and perspectives of study on fluid mechanism in porous medium of low permeability reservoir

概括了低渗储层渗流机理的研究现状,总结了目前研究低渗储层渗流机理实验的方法,指出了现有渗流机理研究方法的不足,探讨了可视化物理模型及先进实验和孔隙级数字岩心结合的方法在油田开发领域内的应用前景。可视化模型实验可以清楚观察到驱替的详细过程,有利于弄清流体在驱替过程中的流动状况。应用有限的实验数据和孔隙级数字岩心相结合的方法,可以研究储层的微观渗流机理、模拟驱替实验、评价驱替效果等等。

By outlining the present state of study on fluid mechan- ics in porous medium of low permeability reservoir and sum- marizing the present experimental approach to the fluid me- chanics in low permeability reservoir,the imperfection in the current research methods on the fluid mechanics are pointed out.and the application perspectives of the method integrat- ed the visualization of physical model and the advanced ex- periments with the digital core of pore level in the sphere of oilfield development.The detailed processes of displacement can be clearly observed through the experiment of visualiza- tion model,helpful to ascertain the flowing state of fluid in the process of displacement.The method integrated limited experimental data and the digital core of pore level can be used to the studies on the fluid microscopic mechanics in por- ous medium of low permeabiiity reservoir,the simulation ex- periment of displacement,the evaluation of displacement effect,and so on.
