摘要
聚表剂作为一种新型化学驱油剂,在大庆油田开展了多项矿场试验,部分试验区已取得显著的增油降水效果,但现场存在聚表剂的官能团结构及驱油机理尚不清晰等问题。本文采用元素分析、红外光谱、质谱等多种分析技术对Ⅰ型、Ⅲ型和BⅢ型3种聚表剂的化学结构进行分析,确定了聚表剂含有碳、氢、氧等7种化学元素,聚表剂分子中含有苯基和烷基苯基等10种官能团,聚表剂化学结构的确定对于进一步指导聚表剂在矿场中的实际应用具有重要指导意义。
Polymer surfactant is a kind of novel chemical oil displacement agent,which was used in Daqing Oilfield.The effects of increasing oil and decreasing water were obtained in some test areas.However,the chemical structure and oil displacement mechanism were uncertain.The structures of Ⅰ,Ⅲ and B Ⅲ Polymer surfactant were characterized by elemental analysis,IR spectroscopy and mass spectroscopy.There are carbon,hydrogen,oxygen and other elements in polymer surfactant.There are ten kinds of groups such as phenyl,alkylphenyl and et al.Determination of chemical structure is important for the application of polymer surfactant in oilfield.
