摘　　要：DSB变质岩潜山油藏1983年投入开采以来,经历27年的开发,目前进入高含水开发后期。如何准确认识潜山裂缝内部油藏剩余油分布,改善油田开发效果,是目前油田开发中的主要问题。在裂缝建模技术的基础上,利用油藏水锥研究与双孔双渗油藏数值模拟相结合且互为验证,对DSB变质岩潜山油藏进行了研究,清晰展现油田剩余油空间分布,为油田调整挖潜提供依据。DSB metamorphic hill reservoir was put into development in 1983.After 27 years development,later stage of high water-cut development has come,and the problem in this stage is how to make clear the distribution of residual oil in buried hill reservoir to improve the oilfield development effect.Based on the fracture modeling technology,research of the reservoir water-coning was combined with the numerical simulation technology for dual-porosity and dual-permeability reservoir to research DSB reservoir.The distribution understanding of residual oil can provide bases for improving the oilfield development effect.
