Meandering river point bar physical simulation water flooding experiment and analysis
Journal Title: Scholars Bulletin - Year 2016, Vol 2, Issue 5
Abstract
Abstract:In order to more intuitive understanding of the meandering river point dam reservoir characteristics and effect of water flooding, based on the actual reservoir configuration characteristic, design large scale core physical model. This experiment has the model size is big, high degree of simulation, and the characteristics of the high degree of injection-production controllable, a note four mining method is adopted to improve the water flooding experiment. Water flooding stage is 40.2%, the total recovery degree according to its characteristic curve can be divided into three stages. On analyzing the characteristic of the reservoir internal structure and the structure of degree of water flooding stage of single well production and the influence of residual oil distribution. Combined with the actual scene, and based on the blocking effect of abandoned channel classifying production well, abandoned channel blocking effect is different with different values can result in water flooded production well, the point at the bottom of the dam caused by the different remaining oil distribution. The experimental results show that the production well of different store condition, its recovery degree is different, the influence of seepage channel advantage is also different. Keywords: physical model; point bar; residual oil; architecture.
