摘要: 胜利油田封闭断块稠油油藏储层发育,非均质性严重,流体物性差,油水关系复杂,开采难度大,采出程度低。
针对该类油藏开发中存在的注汽压力高、注汽效果差、周期产油量低等问题,分别开展了CO2、高分子降黏剂FSP 体
系以及二者协同作用改善稠油物性机理研究。在矿场应用中,结合油藏地质特点,不同开发特征井应用不同的化学吞
吐工艺组合,现场实施6 口井,截至目前累计增油2 500 t,且各井仍持续见效,取得了良好的增油降水效果。

Abstract: The heavy oil reservoir in Shengli Oilfield is typically double-low unit. The present recovery is very low,and
exploitation is difficult because of poor reservoir development and fluid properties. Due to the serious problems of high-pressure
steam injection and poor steam injection effect and low-cycle oi1 production in the reservoir,this paper studies improvement
of heavy oi1 properties through injection CO2,FSP oil-soluble viscosity reducer. According to the geological characteristics of
reservoirs,the different chemical huffing and puffing technology are applied in wells of different development characteristics.
It achieved obvious effects of oil incremental.

Key words: heavy oil fault block reservoir, carbon dioxide, FSP viscosity reducer, producing energy, chemical huffing andpuffing technology
