摘　　要：采用人造微观储层模型模拟实际建库过程中的各个过程。应用可视化方法,观察各驱替过程的驱替现象,可以清楚地观察到流体进入和驱替的全过程,并分析了储气库的注气、储气机理。天然气驱油和水的效果十分明显,说明高含水后期油藏进行储气库建设,其注气、储气能力较好。在渗透率较高的高倾角油藏中局部注气时,其重力驱动效果明显,气液界面不平行。随着注气速度的增加,油藏的注入能力和储气能力将进一步加强。The process of storage construction is modeled by using artificial micro reservoir model.Visualization method is used to observe the displacement process.The whole process of fluid entering and displacing can be clearly seen.The mechanism of gas injection and preservation in gas storage is analyzed.Displacing oil and water by gas is very effective,showing gas storage construction in late high water cut stage will have good gas injection and preservation capability.When injecting gas locally in reservoirs with high permeability and large dip angle,the gravity drainage is obvious,and gas-liquid interface is not parallel.As the increasing of gas injection rate,both the injection and storage capacity of the reservoir will improve further.
