位于我国河南省南部唐河与泌县之间的泌阳凹陷是新生代富含油气的小型断陷。其主要的生、储油层段为核桃园组 ,展布面积达 970 km² ,最大生油层厚度达 730 m。通过对研究区油气运移的分析和地层剥蚀对油气分布的影响推断 ,泌阳凹陷除在凹陷中心发育有生油中心外,在双河和井楼之间还发育有一个次要的生油洼陷。

The article analyses the oil & gas distribution and migration character in Biyang depression,and the denuded influence to the oil & gas distribution,and statistics the stratum’s datum and oiliness proportion protracts the oil distributing figures of each phase,and can see the changing of oil and gas distribution in different periods,simultaneity,applies the stratum denudation principle to illustrate the migration direction of the oil and gas.
