泌阳凹陷核三段古地貌恢复

Restoration of Paleo-Landscape the Hesan Member, Biyang Depression

古地貌是控制盆地内沉积相发育与分布的一个主要因素，同时在一定程度上控制着后期油藏的储盖组合，因此研究古地貌有利于指导下一步的油气勘探。本文采用井一震联合地层恢复法，求取现今残留地层厚度，并用声波时差法计算剥蚀量校正，恢复了南裹盆地泌阳凹陷南部陡坡带古近系各主要沉积时期（核三下段、核三上段）古地貌，探讨了其古地貌演化特征。

The ancient landseape is to control the basin facies development and distribution of a major factor, while some control over the Houqi reservoir＇s reservoirs, and so the ancient landscape with Li Yu Yan Jiu guide the next step of Youqi exploration. In this paper, well - seismic stratigraphie recovery method, to obtain the current residue formation thickness, and with acoustic transit time method denudation correction, restoring Nanxiang basin Biyang southern steep slope of the Paleogene the main deposition period （third nuclear lower nuclear Three previous paragraph） the ancient landscape, of its ancient landscape evolution.
