摘要
考察了不同温度和不同水作用程度下 ,原油内萘菲系列化合物的浓度及组成变化规律 .在水的作用下 ,大庆陆相原油中的甲基菲浓度保持相对稳定 ,二甲基菲的浓度略显升高 ,菲及萘系列化合物的浓度有不同程度降低 .根据龙虎泡高台子层油藏原油中甲基菲视浓度、菲与甲基菲视浓度比变化规律 ,描述的原油聚集途径与油藏所处的地质条件相符 .
By experiment, we have observed the change of the concentration and composition of the series compounds of naphthalene and phenanthrene in oil, under different temperature and different water\|oil ratio. After water treatment, the concentration of methylphenanthrene in Daqing terrestrial facies oil keeps stable relatively, the concentration of dimethylphenanthrene is appreciably increasing, and that of phenanthrene and the series compounds of naphthalene decrease in different pitch. The oil accumulation approach corresponds with the geologic conditions of Longhupao Gaotaizi reservoir which has been given by the changing of the phenanthrene relative concentration and the relative concentration ratio of dimethylnaphthalene to methylphenanthrene.
