准确识别油水井间的优势流场，确定存在于优势流场中的油水井对，对于高含水期油藏制定有针对性的控水增油调整措施十分必要。以大庆油田某高含水期区块为研究对象，采用油水井相关性判断优势流场方法结合储层沉积微相分析及流管法数值模拟技术，在综合分析研究区块不同日注水量区间的注水井的样本概率及对全区流量的贡献大小的基础上，得到了不同级别的流场界限，确定了存在于优势流场中的油水井对。且根据流场分布情况，对存在于优势流场中油水井进行相应的精细调整措施，调整后全区综合含水由96.7  下降到95.1 ，日增油量稳定在43.5 t，调整效果明显。

To accurately identify the advantaged flow filed between oil & injection well and determine the oil & injection well pairs in advantaged flow filed is of great significance for the method of water controlling and oil increasing in reservoir at high water cut period. In response to this problem, we take Daqing oilfield as an example to research the advantaged flow channel distribution between oil well and injection well and to determine oil and injection well pairs with advantaged flow field in high water cut by the correlation coefficient method between oil wells and injection wells and reservoir sedimentary facies and flow tube numerical simulation method. And the advantaged flow field is graded through the new method of daily water injection and oil wells water cut probability distribution. And fine adjustment measures are developed to tap residual oil in high water cut according to the identified flow field distribution. After adjustment, the overall water cut is reduced from 96.7% to 95.1% and daily oil increase is stabilized at 43.5t.
