【摘要】 综合地震反射强弱及反射形态的差异,将地震反射类型划分为串珠状反射、片状反射、杂乱反射和弱反射,并对串珠状反射和片状反射进行细分。总结塔中西部下奥陶统鹰山组地震反射特征与岩溶储层对应关系,在此基础上比较每种地震反射类型所对应地质特征的差异,归纳形成四种地震反射类型的地质原因。更多还原

【Abstract】 Combined with the seismic reflection strength and shapes,this article divides seismic reflection into four types,including the string beads reflection,the flaky reflection,the disorderly reflection and the weak reflection.And the string beads reflection and the flaky reflection are subdivided.Based on the summary of the corresponding relations between seismic profile and karst reservoir in Yingshan Formation of the Lower Ordovician in western Tazhong area,the corresponding geological characteristics of the every kind of seismic reflection types have been carefully analyzed.The geological causes of the four seismic reflection types are summed up from the differences of these geological characteristics.更多还原
