河南双河油田Ⅴ_上层系非均质性严重,油藏温度高达80.3℃,经多种聚合物性能评价,优选出耐高温的聚合物,提出了以水驱井网为基础、完善聚驱井网和提高井网控制程度的井网调整方法,并利用油藏数值模拟方法对注聚参数(注入速度,段塞量,段塞结构)进行了优化。现场实施后,取得了显著的效果,阶段累积增油2.35×104t,形成了一套二类储量高温聚合物驱方案设计技术。
The Ⅴ_upper system of Shuanghe Oilfield in Henan Province is seriously heterogeneous. The reservoir temperature is as high as 80.3 ℃. Polymers with high temperature resistance are selected through evaluation of various polymers. Well pattern adjustment and well pattern adjustment to improve the control of the well pattern. The injection parameters, such as injection velocity, slug mass and slug structure, are optimized by reservoir numerical simulation. After the implementation of the site, a significant effect has been achieved, with 2.35 × 104t cumulative oil increase in the stage, forming a set of design technologies for a type-two high-temperature polymer flooding program.
