| 摘 要： | 我国多数油田经过多年注水开发,综合含水已超过90%,而采出程度低于35%,如何提高油田采收率是高含水油田急需解决的难题。目前,聚合物驱油是工业化应用程度最高的一项提高采收率技术,但由于聚合物产品性能差异和油田现场对污水处理的需要,多数聚合物不适宜高温高盐油田的现场驱油试验。本文以胜坨高温高盐油藏的地质条件为依托,在对聚合物驱油效果影响因素分析的基础上,研究了适合于高温高盐油藏强化采油的聚合物性能指标,优选了具有梳形结构的KYPAM聚合物为胜坨油田的驱替剂。该性能指标的提出对国内外高温高盐油藏进行聚合物驱油具有重要的指导意义。

| Abstract: | For many oil fields,the water-cut rate has been over 90% and the ratio of total oil produced to the OOIP has been less than 35%.How to enhance oil recovery is an urgent problem for high-water-cut fields.Presently,the technique of polymer EOR has been applied to many oil fields to increase production,but most polymers are not feasible for EOR for high-temperature and high-salinity reservoirs because of the performance discrepancy of polymers and the requirements for produced water disposal.Using the high-temperature and high-salinity reservoirs in Shengtuo Oilfield as an example,this paper studies the performance indexes of the polymers suitable for EOR for high-temperature and high-salinity reservoirs,selects the comb-shaped polymer KYPAM as the flooding agent in Shengtuo Oilfield on the basis of influence factors analysis of polymer flooding.The suggestion of the performance index is of value to polymer flooding for high-temperature and high-salinity reservoirs. |
