摘要
The foreland thrust belt in Tarim Basin is rich in natural gas resources,where the hydrocarbons are mainly found in structural traps related with the foreland thrust belt and the thrust faults.According to the structural characteristics of the foreland thrust belt,nine types of petroliferous structural styles are built up.The variety of structural zones and styles and the diversity of spatial assemblages with source rock,reservoir rock and cap rock can form various oil-gas accumulation patterns,of which the fault and cap rocks are the decisive factors for natural gas accumulation in this area,because the spatial assemblages of fault-source-reservoir-cap rocks dominated by fault development determine the trap shape,oil-gas deliverability,trap sealing and charging rate.
