CHEMICALS IN HEAT TOLERATE AND SALT RESISTANT FLOODING

综述了近年来国内外耐温抗盐驱油用聚合物和驱油用表面活性剂研究现状和取得的主要成果,驱油用聚合物研发主要通过耐温抗盐功能单体共聚的方式或特殊分子结构控制的方式提高其耐温抗盐性能,已开发出缔合型、两性离子型、嵌段结构、星型结构、交联结构等系列聚合物;驱油表面活性剂研发通过合成原料优化和分子结构改进的方式已有甜菜碱型、阴非两性、挛连型等系类产品的报道和应用。深入分析了不同新型驱油用化学剂产品性能及应用前景,提出了我国耐温抗盐驱油剂的下步主要攻关方向。

Current situations and study achievements in polymer for heat tolerate and salt resistant flooding andflooding with surfactant have been summarized home.The performance of heat tolerate and salt resistant functions isoften improved through the ways of copolymerizing monomer or controlling the structure of some special moleculesXIV Journal of Southwest Petroleum University(Science & Technology Edition) Jun.2011in polymer flooding.Up to now,multicomponent copolymerization includes associating type,zwitterionic type,block structure,star structure,and crosslinked structure.A series of products have been applied which includeoxyneurine surfactant,anion and non-ionic ampholytics and Gemini surfactant by optimizing the raw materials andimproving the molecular structure in surfactants oil driving.The performance and applied feasibility of differentnew type of chemical agents for oil driving are deeply analysized in this article,and the next goal for chemicals withheat tolerate and salt resistance flooding is pointed out.
