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。
Gudong Oilfield eight districts after nearly a year of polymer flooding test, have seen a better oil precipitation effect. The daily oil level increased from 407t / d to 720t / d, the comprehensive water content decreased from 93.2% to 82.7%, and the cumulative oil increase was 5.8 × 104t. At present, the area is in the period of validity and reflects the dynamic characteristics of pre-production and injection of polymer flooding test. Through the study of the dynamic characteristics of pre-injection and injection, a preliminary understanding is reached: “One well and one system” is an important technical measure to further improve the polymer flooding effect in the future. The mine should adopt “Encryption-Re-Encryption” sampling Laboratory methods, injection and production should be controlled at 1: 1 is appropriate, reasonable control of production parameters, to extend the high-yield wells, to further strengthen the inter-layer, in-depth study.
