| 摘 要： | 野外露头、钻井和地震资料均揭示库车坳陷发育大量盐构造,并影响了油气成藏过程.盐构造类型主要包括：断层传播褶皱、断层转折褶皱、滑脱褶皱、三角带、逆冲推覆构造、突起构造及其混生构造样式等.构造挤压和差异负荷作用是库车坳陷盐构造形成的主要动力,平衡剖面复原结果表明,盐构造发育过程主要经历了楔状地层、滑脱背斜和构造强烈活动期等3个阶段.受盐构造影响,库车坳陷存在多种圈闭类型和成藏模式,油气主要聚集在盐下圈闭中.

| Abstract: | Outcrops, well and seismic data demonstrate that many salt structures have developed in the Kuqa depression, northern Tarim basin, Northwest China. The salt structures have important influence on the forming process of hydrocarbon pools, and their types involve fault-propagation folds, fault-bend folds, fault-detachment folds, triangle zones, thrusts, pop-ups and their composites etc. Tectonic compression and differential loading are major forming mechanisms of salt structures in the Kuqa depression. On the basis of restoration sections, the forming process of salt structures can be divided into three stages, namely wedged-bed, detachment anticlines, and intensely tectonic active. Influenced by the salt structures in the Kuqa depression, them are many types of structural traps and forming models of hydrocarbon pools. Majority of oil and gas locates in the sub-salt traps. |
