摘要:

在分析合肥盆地钻测井和地震等地球物理资料的基础上,对北淮阳构造带推覆构造进行了研究,确定了印支期推覆构造的存在,探讨了印支期推覆构造的模式、动力学背景和油气意义。认为,印支期合肥盆地与北淮阳构造带组成统一的推覆构造系统,其动力学背景是华北陆块深部地壳向造山带内部的陆内俯冲。印支期构造运动为典型的大陆内部构造,并非经“B”式俯冲形成的碰撞造山运动。印支期逆冲推覆构造对油气的保存是有利的。

Abstract:

On the basis of analysing drilling and logging data and geophysical profiles, nappe structures in north Huaiyang tectonic zone have been studied,and the existence,pattern, dynamic background and hydrocarbon significance of Indosinian nappe structures have also been discussed.It is suggested that the unified nappe structural system might be composed of north Huaiyang tectonic zone and Hefei basin in Indosinian period, and the dynamic background might be resulted from the intra-continental subduction of deep crust of North China plate towards the inner orogenic zone.The Indosinian tectonic movement belongs to typical continental structures,and the thrusting nappe structures formed in the Indosinian period might be favorable to hydrocarbon preservation.

Key words: nappe structure, intra-continental subduction, Hefei basin, north Huaiyang tectonic zone
