摘要通過對世界上壓扭性盆地的成盆機制、演化模式和油氣地質特點分析，總結壓扭性盆地具有6個方面的石油地質特徵：壓扭作用期間盆地的沉積速率較高，一般形成較厚的粗碎屑沉積，它們常構成很好的油氣儲集層：盆地的烴源巖往住來自於前壓扭期砂成的富含有機質的巖石，但在強烈的壓扭作用期間，在沖斷帶的前緣深坳陷（前淵）中有可能發育深水半深水相的烴源巖；壓扭（張扭）作用期間形成的雁行式褶皺（包括背斜和斷鼻等）往住是很好的油氣圈閉；壓扭作用易於成藏；壓扭作用可以促進有機質的成熟生烴作用；壓扭性盆地的周邊沖斷帶是油氣賦存的有利部位。The discriminant analysis on inorganic element abundance shows that the palaeosedimentary environment of jurassic in the yanqi basin is close to that of dongying sag
