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。
Based on the geological balance profile technique, the dynamic evolution of the Budate Group buried hill in the Beier sag was deduced. The formation time and genesis of various buried hills in the area were first determined. Based on this, the buried hills of the Budate Group in the Beier sag Classified. The results show that there are three types of buried hills in the study area, that is, buried hills in the early paleotopography, buried hills with long-term inherited development controlled by faults, and post-buried hills formed by mid-term deformation, and the evolution of various buried hills Different. Based on the dynamic analysis of balanced geological sections, the relationship between various buried hill evolution and hydrocarbon accumulation is explained and the distribution range of various buried hills is calibrated. It is pointed out that the buried hill and the buried hill are more favorable Accumulation of hydrocarbon accumulation.
