摘　　要：依据济阳坳陷近几年发现的一些反转构造 ,从构造转型和构造转型期角度对其演化史进行了分析 ,认为济阳坳陷的演化经历过四次大的周期性构造转型 ;指出孔店组沉积时期是济阳坳陷从中、古生界构造体系向第三系构造体系转换的重要转型期。探讨了各转型期对坳陷深层烃源岩分布和成烃演化的影响 。The basin evolution history is analyzed in the view of structural transition and its stage on the basis of some reversal structures founded in recent years in Jiyang depression. The research shows that four main periodic structural transitional stages have appeared during the whole evolutional process. It is pointed out that the sedimentary stage of Kongdian group is the important transitional one from the structural system of the Mesozoic?Paleozoic to that of the Tertiary. The influences of each transitional stage on deep source rock distribution and hydrocarbon?generating evolution of the depression are discussed, and it is also put forward that the principles and directions should be followed in the deep exploration of this area.
