Abstract: The Gaoyou Sag of Subei Basin is a complicated oil-gas bearing area,formed and controlled by faulting and folding.It contains multitude of source rocks,reservoirs and different types of oil-gas pools.The fault-structural zones on bath sides of the deep sag part are favorable zones of oil-gas accumulanon.There are many types of oil-gas pools,such as structural,faulted block,lithological,buried hills,etc,in different structural parts of these zones.The existence of ail-gas pools is related to multiple tectonic movement,which of constitute favorable lithologic-fades conditions and suitable matching of the faulting movements with the maturation period of,hydrocarbons in a vast area on both sides of the deep sag.These causalities favored oil-gas migration,and accumulation and provided favorable geological condition of high productivily.The Gaoyou Sag can be placed one of the most prospective sags in the Subri Basin.

摘要： 苏北盆地中的高邮凹陷,具有多层生油岩,多套含油气层系和多种类型的油气藏,足一个主要受断层次和构造控制的复合油气区.凹陷两测的断裂带,是油气富集带.带上的不同构造部位分布有构造,断块,岩性和基岩等油气藏.这批油气藏的形成,是由于多期的构造活动,使深洼两侧的广大地区成为戴南,三垛期沉积的有利相带,以及由于断层的活动期写烃类的成熟期的恰当匹配,从而为油气的运移提供了良好通道,为油气的聚集提供了贮存空间,为油井的高产提供了有利地质条件,成了苏北盆地诸凹陷中最富有勘探前景的凹陷之一.
