葡北油田的单井连通关系比较复杂,聚驱开发难度较大,采用相控建模技术,进行聚合物驱全过程跟踪拟合工作,成效显著。葡北油田属于窄小砂体油田,油层发育规模小、物性差、连通差。与大庆长垣北部油田相比,单井连通关系更加复杂,注采完善程度低,聚驱开发难度 The connection between single well in Pubei Oilfield is complicated, and it is more difficult to develop the poly flooding. By using the phased control modeling technique, the fitting of the whole process of polymer flooding is completed with remarkable results. Pubei oil field belongs to a narrow sand body oil field, the development of small scale, poor physical properties, poor connectivity. Compared with the Daqing Changyuan northern oilfield, single-well connectivity is more complicated, the perfection of injection and mining is low, and the difficulty of poly flooding development
