摘　　要：苏北盆地的油气圈闭以"贫、小、碎、散"著称,是我国东部极复杂小断块中的代表。而天长箕状断陷斜坡环境的断块更加破碎,其特殊的构造运动背景造就了该地区极复杂的断裂体系,油气的运移和油藏的形成与之密不可分。研究认识断裂是深化勘探和实现滚动勘探开发的前提。断裂研究着眼点既要掌握局部,更要从成因联系上来研究一个整体———断裂体系。本文着重于方法认识,旨在对其他类似地区的油气勘探有一定的借鉴作用。The petroleum in the Subei basin is famous for poor,small,beraking to pieces,and scattering in the exploration history of Chinese petroleum,and it is a typical case of the most complex and small faultlock in the East of China.But the faultblock of Tianchang halfgrabenlike depression is more breaking and scattering.Formation of complex fault system depends on its special tectogenesis background,and oilgas migration and oil reservoir formation are closely impartibility with it.Analysis of fault system is a basis for futher realizing oil exploration and development.Fault system research mast not only master part,but also master all.This paper emphasizes method study of fault system,which is also to provide a reference for petroleum exploration in similar tectonic background.
