中文摘要: 研究驱油剂耐温抗盐的微观机理,为驱油剂的分子设计和优化使用提供理论依据,对于提高石油采收率,维护我国石油安全具有重要意义。本项目拟选取不同类型的表面活性剂和聚合物改性用功能性单体,在20℃至90℃温度范围内,考察其在不同类型和浓度盐溶液中的溶解性能、界面活性,通过微量热技术,从宏观上研究各种盐离子与表面活性剂或功能性单体在水溶液中产生沉淀或发生相分离的热力学机理;结合波谱分析手段,从静态与动态两个方面,在分子水平上揭示盐离子、水分子及表面活性剂分子间的相互作用和聚集行为,阐明驱油剂的分子结构与其耐温抗盐性能之间的关系。

英文摘要: EOR is significant for ensuring the petroleum safety of China. So it is necessary to study the microscopic mehanism on temperature resistance and salt tolerance of oil displacement agent, which can supply theoretical guide for the molecular design and optimization of novel oil diaplacement agent. In order to achieve this goal,the solubility and interfacial activity of various surfactants and functional monomers for polymer modification will be investigated at the temperature range from 20 to 90℃ with different types and concentration of salt solution. Thermodynamic mechanism of precipitation or phase separation caused by the interaction between surfactant or functional monomer and salt ions will be studied through the use of microcalorimetric measurement.The static and dynamic molecular interactions among salt ions, water molecule and surfactant molecular as well as aggregation behavior will be investigated at the molecular level by spectrum analysis with the purpose of building the structure-property correlation for surfactant and polymer about temperature resistance and salt tolerance.
