| 摘 要： | 库车盆地秋里塔格构造带的构造圈闭具有上、下分层的特征,且上构造层的圈闭与下构造层的圈闭完全不同。上构造层圈闭位于第三系膏盐岩滑脱面之上,主要有断层传播褶皱、滑脱褶皱和盐拱背斜等类型。这些圈闭常以下第三系和上第三系吉迪克组及康村组砂岩为储层,以上第三系库车组泥岩作为区域性盖层。下构造层圈闭位于下第三系膏盐岩滑脱面之下,三叠侏罗系煤层滑脱面之上,主要有断层转折褶皱、断层转折——断层转折叠加褶皱等构造圈闭类型;这类圈闭以三叠系、侏罗系和白垩系砂岩为储层,以下第三系膏盐层为区域性盖层。文章分析了库车盆地的油气勘探方向,认为秋里塔格构造带的东段较西段有利,下构造层较上构造层有利。

| Abstract: | There was a layering character from shallow to deep for structure traps of the Qiulitage structure belt in the Kuqa Basin, northwest Tarim. The shallow structure traps, which were located above the Paleogene salt layers, included mainly fault propagation fold, detachment fold and salt fold. The deep structure traps, located below the Paleogene salt layers, were mainly composed of fault bend fold and superposition of fault bend fold. Both of them had different reservoir caprock associations. Namely, the shallow traps had the reservoirs and caprocks of the Paleogene and Neogene Jidike, Kangcun sandstones, and the Neogene Kuqa mudstones respectively; the deep traps had the ones of the Triassic, Jurassic and Cretaceous sandstones, and the Paleogene salt layers respectively. Based on the petroleum geological features, the authors presented the oil and gas potential for the near future to explore in this area as follows: the east and the deep ones might be more promising than that of the west and the shallow. |
