| 摘 要： | 选择川西孝泉-新场气田和松辽南部后五家户气田为研究区,采集14口井井中化探样品,测试热释烃、酸解烃、荧光等指标,进行了烃类垂向微运移的研究.由于岩石物性的影响,热释烃、荧光等指标显示不同程度的正向梯度,但酸解烃指标在油气田井中局部层段垂向分布特征显示负向梯度,或与其它化探指标没有相关关系.建立相应的微渗漏模型,并进行动力学模拟,模拟结果和实测资料较吻合. |

| Abstract: | The Xiaoquan-Xinchang Gas Field in west Sichuan and the Houwujiahu Gas Field in south Songliao Basin were selected as the study areas, and core samples from 14 wells were analyzed for such indices as heating released hydrocarbon, acid extracted hydrocarbon and fluorescence so as to study vertical hydrocarbon micromigration. Being influenced by the physical properties of rocks, heating-released hydrocarbon and fluorescence indices show positive gradient in varying degrees. Acid extracted hydrocarbon concentration, however, shows negative gradient in some sectors of oil and gas wells or is not correlative with other geochemical indices. Based on these results, the authors established the hydrocarbon microseepage model and made dynamic simulation. The results of simulation coincide with the measured data. |
| Keywords: | oil and gas microseepage geochemical index features dynamic simulation |
