缝洞单元注水开发物理模拟
Physical simulation of water flooding in fractured-vuggy unit
摘要
Abstract
The model parameters and experimental conditions of physical simulation were gotten based on the field data and similarity theory. A well pattern model of fractured-vuggy unit was established. Using above model, the resistance of every channel corresponding to every production well was studied by the experiment of single phase flow. The oil recovery efficiency , water cut and injection pressure and the distribution rule of residual oil of the model at different injection rate were studied by experiment of water flooding. The results show that the oil recovery efficiency of model increases and the residual oil decreases with the injection rate increasing. When the well is drilled on the top of vug, the residual oil locates on the top of the vug and around the vug edge after water flooding. When the flow path goes through the vug, there is little residual oil after water flooding.关键词
