| 摘 要： | 西峰油田长8低渗储层欠注水井较多,注水效果不好,普通酸液的增注效果不理想,不利于油田长期稳产。针对注水井初投压力高,正常注水后压力上升快,地层吸水能力下降,注入困难,能耗大的问题,通过岩心溶蚀实验,确定了该油田储层主体的氧化型深部酸化工艺。西峰油田13口注水井的现场试验结果表明,使用氧化型深部酸化工艺后,试验井组注入量与吸水指数比措施前大幅度提高,有效解决了油藏欠注问题,为西峰油田油水井增产增注提供了方向。

| Abstract: | There are many less water injection wells in Chang 8 reservoir with low permeability in Xifeng Oilfield. The water injection effect is not good and the increasing injection effect by acid liquid is not ideal, which is not favorable for the long-term stable production. Aimed at the problems as the high initial pressure of injection well, the pressure rising rapidly after normal water injection, the water absorption capacity declining, the injection difficulties and the big energy consumption, we study and de... |
