摘要
Abstract
In order to solve the problem that a large amount of remaining oil has not been produced in Yingmai 2 ultra-deep fractured cavernous reservoir,a visual physical model is prepared based on the characteristics of typical reservoir structures,and physical simulation experiments of EOR with different development methods such as water injection and gas injection are carried out.By comparing the water cut and recovery efficiency at different stages,the effects of different development methods on residual oil production in Yingmai 2 fracture-vuggy reservoir are quantitatively analyzed.The feasibility of alternate development modes of water injection,gas injection and gas water after bottom water flooding is studied by using the prepared fissure-hole model and fault solution model,and the reasonable injection and production modes to further improve the recovery efficiency of Yingmai 2 fractured-vuggy reservoir are as follows:low injection and high production water injection,high injection and low production gas injection and alternate gas injection.Among them,gas-water alternation can greatly improve oil recovery.The research results can provide support for further enhancing oil recovery in Yingmai 2 fracture-vuggy reservoir.关键词
