摘要
通过将裂缝型岩心和孔隙型岩心并联模拟高渗透层和低渗透层进行注水驱替,使用强凝胶对裂缝进行封堵,改善了注入水在低渗透层的波及面积,提高了油井转注井注水效率。
By applying fractured core in parallel with porosity core to simulate high permeability layer and low permeability layer and conducting water-driving-oil displacement experiments and applying fracture plugging with strong gels.The results show that the swept area of injected water in low permeability formation is improved and the efficiency of well-conversion wells is enhanced.
