摘　　要：孤东油田八区经过近一年多的聚合物驱矿场试验，已见到较好的增油降水效果。日产油水平由４０７ｔ／ｄ 上升到７２０ｔ／ｄ，综合含水由９３．２％ 下降到８２．７％ ，累积增油５．８×１０４ｔ。目前该区正处于见效期，并体现了聚合物驱试验的前期注采动态特征。通过对前期注采动态变化特征的研究，得出了初步的认识：即“一井一制”是今后进一步改善聚合物驱效果的重要技术措施，矿场应采用“加密—再加密”的取样化验方法，注采比应控制在１∶１ 为宜，合理控制生产参数，延长油井高产期，进一步加强层间、层内研究。Through about one years polymer flooding field test in the eighth area of Gudong oilfield, good effect of increasing oil and decreasing water appears. Oil production increases from 407 t/d to 720 t/d, composite water cut decreases from 93.2% to 82.7%, cumulative incremental oil has been 5 8×10 4t. Now this area is being at valid period, and the polymer flooding injection production feature at earlier stage appears. It is known by research that “one scheme for one well” is the important technique measure to improve polymer flooding effect next time, the “infill reinfill”sample examination method should be applied in field, the injection production ratio should be controlled at 1∶1, the productive parameters must be controlled reasonable to prolong oil wells high producing period, the study of interlayers and in place needs to strengthen.
