摘　　要：利用测井数据和地震资料,结合残余厚度参数和剥蚀厚度参数,对泌阳凹陷南部陡坡带核二段进行了古地貌恢复,分析表明研究区主要古地貌单元包括古隆起、古坡折带、古沟谷及古凹陷。根据不同古地貌单元及其样式组合对研究区沉积体系的控制作用,分析了研究区发育沉积体系的类型、规模、展布方向等特征,提高了对研究区沉积体系研究的精度,为核二段的开发提供了更多的理论依据。By using the log and seismic data,in combination with the parameter of relic thickness and denudation thickness,the Eh2 palaeogeomorphology in the southern Biyang Depression was restored.The analyses show that the palaeogeomorphologic units include palaeo-uplift,palaeo-slope break belt,palaeo-valley and palaeo-depression.Based on the control of palaeogeomorphologic units and pattern assemblages of sedimentary system in the studied area,the characters of types,size,distribution direction of sedimentary system are analyzed.Enhancing the precision of Eh2 development is improved,it provides theoretical basis for the exploitation research of Eh2 reservoirs.
