| Abstract: | Zhongernan area is one of five polymer oil displacement blocks in Gudao oilfield. In order to increase the swept volume of polymer oil displacement and improve the oil displacement result of the whole block, profile control should carry out before polymer oil displacement or in the early stage of it. Profile control can plug large pore passages and improve polymer entry profile, which is favourable to follow up polymer oil displacement. By means of RE reservoir engineering profile control decision technology, profile control was implemented on 10 wells in the block in the early stage of polymer oil displacement. The oil pressure of the wells increase averagely by 5.31 MPa. Compared with other blocks, the number of polymer breakthrough wells in the block decrease by 20.6% in the corresponding period. |
