摘　　要：油田经过聚驱开发,剩余油分布更加复杂零散,运用油藏数值模拟技术、地质综合分析技术,研究了下二门油田聚合物驱后剩余油分布规律,并提出了聚驱后配套高效挖潜对策:不均匀井网优化重组技术、平面液流转向技术、含油污泥深度调剖技术等,实现了对不同类型潜力区的挖潜,这些配套技术应用于现场实际中,取得了较好效果,对其他油田改善聚驱后开发效果和进一步挖潜地下剩余资源具有重要的指导意义.After polymer flooding,the remaining oil distribution is more complex and scattered.The remaining oil distribution of Xiaermen Oilfield is studied by using reservoir numerical simulation and comprehensive geologic analysis,the different potential tapping measures are put forward for different potential zones:optimization and recombination technology of the irregular well pattern,plane liquid flow turning technology,oily sludge profile control technology,and so on.The applications of the measures gain good results.The results in this paper have reference to the potential tapping of the remaining oil of other oilfields.
