摘　　要：大庆喇萨杏油田聚驱后进入后续水驱阶段的储量逐年增多，为开发这部分储量，实现4000×10^4t稳产，以萨中北一区断东作为典型解剖区，通过精细地质研究，搞清剩余油特点及分布规律，明确聚驱后的剩余油潜力，在此基础上提出重新组合开发层系，重新构建井网系统，利用水平井和直井相结合的调整方式，提出了聚驱后现场试验的实施方案。该方案数值模拟结果表明，聚驱后层系重组、水平井和直井联合井网系统的进一步挖潜方式是可行和经济有效的。The reserves of La, Sa and Xing Oilfields in Daqing increase yearly at subsequent water flooding stage after polymer flooding. How to redevelop and further enhance oil recovery of these reserves will have important meanings to realize steady yield of 4000 million tons for Daqing. This paper analyzes the east Block Sazhongbeil to understand the distribution and characteristics of the remaining oil based on fine geologic study, and then the remaining oil potential after polymer flooding will be determined. According to the research, the well pattern adjustment mode is proposed, including recombination of layer series of development, reconfiguration of well pattern and the assemblage of horizontal wells and vertical wells. Field testing development plan after polymer flooding has been provided. Numerical simulation results of this plan indicate that the mode of recombination of layer series after polymer flooding and the combination of horizontal wells and vertical wells is feasible and economically effective to further improve development effectiveness.
