| 摘 要： | 根据原油沥青质中含有的自由基的电子顺磁共振 ( EPR)谱 g因子与自由基结构有关 ,提出了一种分析混合物样品中成分含量的方法 .按照这种方法只需事先由已知配比混合油样测定的 g值做标准曲线 ,即可由标准曲线法求得未知配比油样成分比例 .这种方法对油藏小层油源性质有明显差异的情况 ,可以用来作单层贡献分析 .还简要讨论了 EPR谱包含的多种信息在理论和应用方面进一步研究的可能性

| Abstract: | The free radicals in crude oil asphaltene can produce a strong EPR signal. The g values of the signal are related to the molecular structures of the free radicals. Based on the relationship between them, a new method is put forward for quantitatively analyzing the composition of a mixed oil sample. The g values of a series of the oil samples of known composition are measured, and the standard relation curves of all components of the samples between g and the percentage concentration x can be plotted. So the percentage concentration of some component of an unknown sample can be determined according to the g value of the sample and the standard curve of the component. This method is used for determining the contribution of oil strata to the yield of a reservoir. The possibility of further investigation of the information obtained from EPR in theory and/or application is also discussed. |
