摘要
现有的数模技术不能对储层渗透率时变机理合理表征;主流数模软件虽功能丰富,但滞后于迅速发展的深部封堵体系研制。针对这两个问题,在黑油模型的基础上,整合储层渗透率时变模块和一种新型深部封堵体系的表征模块,建立综合数学模型,编制了相应的数值模拟软件。算例分析表明,渗透率时变对开发效果影响显著,新型封堵体系能够较好地起到稳油控水,提高采收率的作用。
The permeability of the formation is changing continuously in the flooding process whereas most simulation software can＇ t characterize it appropriately. The prevailing commercial software can＇ t match the rapid development of deep plugging systems. In view of the two problems, new simulation software considering both mechanisms is developed. A simulation case suggests that the dynamic permeability mechanism has a significant influence on reservoir development and the new deep plugging system is effective in enhancing the recovery.
