辽河油田冷43砾岩稠油油藏微观驱油效率研究

针对辽河油田今４３断块区为砾岩稠油油藏的特点，利用该油藏的岩芯铸体薄片制作了６块微观仿真地层模型，使用微观可视化物理模拟技术手段．借助显微镜、摄录机及图像分析技术等，直观地观察和分析研究了砾岩稠油油藏水驱油机理，以及原油粘度和储层孔隙结构对驱替机理和驱替效率的影响，分析了残余油分布特征，并给出了相应的结论．

A Study of Microscopic Oil Displacement Efficiency of Leng-43 Gravel Reservoir of Viscous Crude Oil,Liaohe Oil Field

ix simulated micro-models of the formation were made by using the core casting slices of Well Leng 43-54-566. The water driving mechanism. in the gravel viscous oil reservoir was directly observed by taking the physical simulation techniques of micro-visualization,image analysis technique and by using the microscope and videorecorder. The influence of crude oil's viscosity and the formation porosity on the mechanism and efficiency of oil displacement was analysed. The paper also analysed the distribution features of residual oil and presents corresponding conclusions.
