| 摘 要： | 注水开发过程中的水洗作用是一个以往被忽略,但又十分重要的问题.通过对3口井、时间间隔为20年的6个原油样品系统的地球化学测试与对比研究,探讨了注水开发过程中水洗作用对原油的改造作用以及各种地球化学参数的变化特征和规律.结果表明,在注水开发过程中,水洗作用对芳烃的影响远大于饱和烃,主要表现在芳烃组分的含量明显降低,一些芳烃类化合物的含量和芳烃参数也发生了显著的变化.认为这些变化是注水开发过程中原油遭受水洗作用的特征性标志,并对油源对比和油气运移等研究具有参考意义. |

| Abstract: | Water washing on crude oils during water flooding was an ignored subject in the past, but it is very important in the research of oil-source correlation and oil migration. According to the systematic geochemical test and correlation of 6 oil samples with development time interval of about 20 years from 3 wells, the influence of water washing on oil and the variation characteristics of geochemical parameters were studied. The results show that water washing has more influence on aromatic hydrocarbon than saturate one. Content of aromatics was decreased apparently during water washing, and the content of some aromatic compounds and ratios of some aromatic parameters were also changed prominently, which was considered to be the characteristic sign of water washing, and can be considered to be of some value in the study of oil-source correlation and oil migration. |
