| 摘 要： | 为了探讨柴达木盆地西南古近系-新近系层序地层,为岩性油气藏勘探提供依据,本文在Cross高分辨率层序地层学理论指导下,综合利用露头、岩心、钻井、地震等资料,结合盐湖盆地的沉积特殊性,对柴西南古近系-新近系层序界面进行识别与层序划分.研究认为将柴达木盆地柴西南古近系-新近系地层划分为13个长期旋回更为合理,提出缓坡带、陡坡带、低凸地区和湖盆区4种不同沉积单元的层序发育模式,指出层序旋回结构对岩性圈闭具有重要的控制作用,储集砂岩的发育状况与中期旋回密切相关,有利储层主要发育在旋回结构向上"变深"的非对称型下部.

| Abstract: | Sequence stratigraphic study of the salt lake with lately started and weak foundations in Qaidam Basin is important in many respects. In order to analyze the sequence stratigraphy in Paleogene and Neogene in southwestern Qaidam Basin and provide a foundation for lithologic hydrocarbon reservoir exploration,this paper studies the sequence boundary identification and the sequence classification in Paleogene and Neogene in southwestern Qaidam Basin by using sequence stratigraphic method,and applying outcrop da... |
