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