| 中文摘要:塔里木盆地库车坳陷盐构造发育，根据盐构造的外部形态及其发育程度将其分为盐枕、盐背斜、盐墙、盐株、盐脊、盐席、盐楔、盐川和盐蘑菇等构造祥式，并归纳了各种盐构造的特征及其分布。盐构造对库车场陷的油气成藏起着至关重要的作用，不仅提供了优质的盖层，有利于形成大型圈闭、保持较高的孔隙度，而且有利于油气的运聚形成大型油气田。 |

| Salt Structures in the Kucha Depression and their Role in the Formation of Oil and Gas Accumulations |

| Abstract:Salt structures are well developed in the Kucha depression of the Tarim basin and can be divided into salt pillow, salt anticline, salt wall, salt stock, salt ridge, salt nappe, salt edge, salt glacier and salt mushroom,according to their external shapes and development levels. This paper summarizes the characteristics and distribution of all kinds of salt structures in the Kucha Depression. Salt structures provide good cap rocks, help to form large-size traps, maintain relatively high porosity, and contribute to the migration and accumulation of oil and gas and the formation of large-size oil-gas fields.They are therefore important in the formation of oil and gas accumulations. |
