原油组成对碱-表面活性剂-聚合物三元复合驱的影响
Effect of crude oil composition on ternary composite alkali-surfactant-polymer flooding
摘要
Abstract
The interactions between oil/water samples from different districts in Daqing oilfield with ternary composite alkali-surfactant-polymer(ASP) system were studied. The effects of the crude oil compositions on the crude oil production increment with the ASP system and the properties of the produced fluid were studied. The oil/water samples,extracted active ingredients,raffinate oil and sulfur content in the oil phase were analyzed by means of FTIR,GC-MS and XRF. It was showed that,the characteristic peaks of the active ingredients in the oil/water samples accorded with the features of typical saturated monocarboxylic acids(fatty acids and naphthenic acids). The concentration ofn-alkanes with heavy component in the raffinate oil from the Lamadian oil/water sample was higher,and its composition was closer to that of the surfactant(heavy alkylbenzene sulfonates). It was indicated that,the interfacial tensions between the ASP system and the active ingredients in the oil/water samples or the raffinate oil were high, but there were ultra-low interfacial tensions between the ASP system and the crude oils.关键词
