| 摘要: |
| 准噶尔盆地莫索湾地区原油为多期成藏,前期成藏的原油遭到严重破坏,后期成藏的原油得到较好的保存，因此 原油地球化学特征表现出正常原油与生物降解原油特征的叠合，导致该K油气运移研究比较困难=运用石油地质学理 论,在对原油成熟度与—运移戈系分析的基础上，建立了符合莫索湾地区特点的运聚模型;利用地球化学方法,在研究大 量运移指标的基础上，分析了原油的运移特征。结果表明，由于该区正常原油与生物降解原油的混合，严重影响了生物 标记化合物的分布,因此地层色层效应在原油运移研究中的应用效果较差。 |

| Abstract: |
| There are many filling and entrapping stages of petroleum to reservoirs in Mosuowan area, and oil that anteriorly fills lo reservoirs is badly biodegraded and oil that laterly iills to reservoirs is well preserved，so the geochemical characteristic of oil has combined characteristics of normal and biodegraded oil，and the study on oil migration is not so easy. According tu discussing the relationship between mature and migfation of hydrocarbon, a model that can be applied iri Mosuowan arc；a was developed. And on the basis of analyzing oil geochemical characteristics and a large number of migration parameters，the characteristics of oil migration were explored. The results show that the theory of chromatographic effect cannot be applied veiy well in the research of oil tnigration because of the mixture of normal and bindegraded oil. And apparently y the values of maturation parameters of oil in reservoirs including CPI and sterane w ( C2s,-20R
