摘　　要：南阳凹陷是30多年的老探区,对油气的成藏条件、分布规律都有较深的认识。南阳凹陷北部斜坡带是油气大规模运移的指向地区。该区三角洲砂体发育,存在三个鼻状构造隆起,并发育北西、北东向两组断裂,成藏条件有利。分析认为该区带下一步有三个勘探目标:官庄-魏岗、白秋-张店和东赵庄地区,有望找到1000×104t储量。Rich knowledge have been achieved on hydrocarbon accumulation conditions and distribution patterns in Nanyang depression through exploration activities and re-search over30years.The northern slope in Nanyang de-pression is the directional area of large scale migration of hydrocarbon.In this area,delta sandbodies are well devel-oped,3nose-like structural uplifts exist,and two fault groups of NW and NE trending developed,thus hydrocar-bon accumulation conditions are favorable.Three explo-ration targets are presented for further prospecting in this area including Guanzhuang-Weigang region,Baiqiu-Zhang-dian region and Dongzhaozhuang region.Additional reserves of10million tons are expected in these areas.
