摘要

应用地质平衡剖面技术推演了贝尔凹陷布达特群潜山的动态演化过程,首次厘定了该地区各种潜山的形成时间及成因,并以此为依据,对贝尔凹陷布达特群潜山进行了分类。结果表明,研究区发育3 种类型的潜山,即早期古地貌潜山、长期继承性发育的受断裂控制的同生潜山及中期变形形成的后成潜山,各类潜山的演化过程各异。在对平衡地质剖面进行动态分析的基础上,解释了各种潜山演化与油气成藏的关系,并标定了各种潜山的分布范围,指出后成潜山和同生潜山更有利于油气聚集成藏。

Abstract

The balanced geological section technique was applied in studying the evolving process of buried hills in Berer Depression. For the first time, the formation time and origin of these buried hills were confirmed, the classification shows that there are three kinds of buried hills:①the early formed palaeogeomorphology;②the subsequent buried hills by medium-term deformation; ③contemporaneous buried hills controlled by growth faults. Different buried hills experienced different evolution procession. By analyses of evolution procession of balanced geological section, the relation between evolution of buried hills and oil accumulation was successfully interpreted, the distribution of these threes buried hills was marked on the map. Finally, two kinds of buried hills favorable for exploration were pointed out by comparing with the actual exploration achievements.
