南二、三区东部聚驱开发过程中 ,随着注入量的增加 ,采出井的受效情况出现了较大的差异。为了减缓矛盾 ,保证聚驱整体开发效果 ,我们运用精细地质研究手段 ,结合动静态资料进行优化选井选层 ,并采用数值模拟结果同实际压裂效果相结合、对比的方法对采出井压裂有利时机选取进行了论证。结果表明 :在不同的见效时期下 ,压裂措施都是一种最有效的提高聚驱效果的改造措施 ,这为聚驱过程中如何有效提高最终采收率提供了经验。
During the development of poly flooding in the eastern part of the second and third districts in the south, with the increase of the injection volume, there is a big difference in the efficiency of the production wells. In order to reduce the contradiction and ensure the overall development effect of the polymer flooding, we use the fine geologic research method, combined with the dynamic and static data to optimize the well selection and layer selection. Combining the numerical simulation results with the actual fracturing effect, Favorable timing of the selected argument. The results show that the fracturing measures are the most effective retrofit measures to increase the effect of poly flooding under different effective periods, which provides experiences on how to effectively enhance the final recovery rate during the process of poly - flooding.
