| 摘 要： | 鄂尔多斯盆地中生界三叠系延长组长6油藏为典型的岩性油藏,油藏具有连通性差,非均质性强等特点。通过对康台区长6油藏的分布规律进行研究表明:油藏的分布主要受油源、沉积微相、储层物性等因素的控制。长7优质油页岩为本区提供了充足的油源,长6有利的沉积相带为水下分流河道和分流河道,长4+5的平原沼泽化为本区提供了区域盖层。长7、长6、长4+5的叠置关系为本区提供了非常有利的生储盖配置条件,为油藏的形成提供了有利条件。 |

| Abstract: | Reservoir in the Yanchang formation of Triassic in Ordos basin is a typical lithologic reservoir,which connectivity is poor and strong heterogeneity.Therefore the research has been conducted to the oil reservoir distribution pattern.Research shows that the distribution factors of reservoir mainly control by the high quality of source rock,sedimentary microfacies,petrophysical property.The high quality bituminite of chang 7 provides oil source amply.Chang6 favorable sedimentary facies is underwater distributary channel and distributary channel.Chang 4+5 flood-plains swamp area provides regional seal.The superimposed relationship combination of chang7,chang 6 and chang4+5 provided very favorable conditions of source,reservoir,seal and reservoir forming. |
| Keywords: | lithologic reservoir Chang 6 distribution rule main controlling factor |
