摘要: 从注水替油基本原理出发,根据注水替油基本地质模型总结出影响注水替油效果的3个因素:井筒附近油水置换速率、近井地带的油气富集程度、远井地带油气补充速度,并对注水替油失效井进行分类总结,最终针对不同类型注水失效提出相应的治理方法。Abstract: According to the basic principles of replacing oil by water flooding, we have summarized 3 factors which affect flooding effect based on geological models, including the turnover rate of oil and water near to wellbore, the oil and gas enrichment level of immediate vicinity of wellbore and the oil and gas replenishment rate of distant place of wellbore. The wells failed in water flooding have been classified and the corresponding countermeasures have been put forward.
