研究认为进入特高含水期的真武油田依然存在剩余油富集区，提出了分类研究、分类治理、改善水驱调整思路。对特高含水单元在精细描述微构造、隔夹层、低序级断层的基础上采取多种手段精细挖潜；对中高含水单元在剩余油分类评价的基础上实施井网完善与重组；对中低含水单元，结合储层改造，实施注采配套完善。通过综合治理，油田水驱开发效果得到明显改善。%The studies show that in Zhenwu Oilfield, which has entered into extra - high water cut stage, there are still the potential regions of remaining oil. Thus, the idea of classified study and tackling for improving water flooding was pro-posed. For extra - high water cut units, the fine potential tapping was conducted by the fine description of micro - struc- ture, interlayer, and low - level sequence faults. For middle - high water cut units, the perfection and rearrangement of well pattern was carried out according to the classified evaluation of the remaining oil. For middle - low water cut units, the in- jection -production perfection was conducted by combining with reservoir stimulation. The effectiveness of oilfield water flooding development has been improved obviously by the comprehensive treatment and adjustment.
