摘要

碳酸盐岩油藏注水替油技术在塔河油田推广应用以来,取得了良好的增产效果,但随着注水井和注水量的增加,不同区块的注水井表现出独特的动态特征.油井注水失效后表现出累计注采比远低于区域内其它注水井,注水提前失效,生产效果大幅下降.

Abstract

Thanks to the application of water injection in carbonate reservoirs in the Tahe Oilfield, oil productions were improved obviously. The water injection wells in different regions displayed unique dynamic characteristics when more wells were injected with water and more water was injected in wells. After water injection failure, the cumulative injection production ratio was much lower than that of the other wells in the area. Productions decreased sharply when water injections failed in advance.
