济阳坳陷发育的同沉积背斜构造可分为同沉积背斜和同沉积鼻状构造，它们在形成和发展中，重力起主导作用，滑塌是主要形式。 - 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
摘要通过对世界上压扭性盆地的成盆机制、演化模式和油气地质特点分析，总结压扭性盆地具有6个方面的石油地质特征：压扭作用期间盆地的沉积速率较高，一般形成较厚的粗碎屑沉积，它们常构成很好的油气储集层：盆地的烃源岩往住来自于前压扭期砂成的富含有机质的岩石，但在强烈的压扭作用期间，在冲断带的前缘深坳陷（前渊）中有可能发育深水半深水相的烃源岩；压扭（张扭）作用期间形成的雁行式褶皱（包括背斜和断鼻等）往住是很好的油气圈闭；压扭作用易于成藏；压扭作用可以促进有机质的成熟生烃作用；压扭性盆地的周边冲断带是油气赋存的有利部位。
