水聚交叉井网会造成水聚干扰现象, 导致聚驱效果变差. 针对此问题, 结合海上典型注聚油田地质油藏特征, 利用数值模拟软件开展水聚干扰机理及影响因素研究, 并在此基础上制定相应的调整策略. 矿场试验表明, 通过针对性优化注水井转注聚顺序及水聚注入强度, 有效控制了分批次转注聚期间出现的水聚干扰, 油井受益率达到 86%, 实现净增油 482.0× 10~ 4 m~ 3, 提高采出程度 5.1%. 聚驱降水增油效果稳定, 达到改善聚驱开发效果的目的.

Abstract: Water and polymer cross-well pattern will cause water and polymer flooding interference, which will result in poor polymer flooding effect. In view of this problem, combining with the geological reservoir characteristics of typical offshore polymer injection oilfields, by using the numerical simulation software, the study on mechanism and influencing factors of water and polymer interference was carried out, and on this basis, corresponding adjustment strategies were made. Field tests show …
