| 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,andexploitation is difficult because of poor reservoir development and fluid properties. Due to the serious problems of high-pressuresteam injection and poor steam injection effect and low-cycle oi1 production in the reservoir,this paper studies improvementof heavy oi1 properties through injection CO2,FSP oil-soluble viscosity reducer. According to the geological characteristics ofreservoirs,the different chemical huffing and puffing technology are applied in wells of different development characteristics.It achieved obvious effects of oil incremental. |
