The basin - formed mechanism, evolution model and petroliferous geological features of compresso - shear basins in the world are analyzed, by which six aspects of the features are summarized as follows : 1 ) in the compresso - shear process, the sedimentary speed of basin is high, forming thicker coarse - grained clastic rocks which normally shape good petroleum reservoir ; 2 ) the source rocks of basin tend to coming from the organic matter - enriched rocks formed in pre - compresso - shear stages, except that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in pre - compresso - shear stages, e4xcept that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in frontal of deep depression ( fore deep ) of thrust belt ; 3 ) the en echelon folds ( including anticline and fault - nose structure ) are generally as good oil traps ; 4 ) the compresso - shear process is helpful to hydrocarbon accumulation ; 5 ) it may promote the maturity and hydrocarbon - generating process of organic matte, and 6 ) the thrust belts in the surrounding areas of compresso - shear basin are favorable are favorable domains for petroleum concentration
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。
