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 faultlock in the East of China.But the faultblock of Tianchang halfgrabenlike depression is more breaking and scattering.Formation of complex fault system depends on its special tectogenesis background,and oilgas 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.
