摘　　要：泌阳凹陷经过30年的勘探,“九五”末根据油田勘探形势做出勘探思路的重大调整,重返老区坚持富油凹陷勘探。通过深化地质研究认识到北部斜坡带浅层复杂断块群油气成藏条件好,勘探潜力大。针对北部斜坡带油层埋藏浅、断块构造复杂的特点,采用保护浅层反射信息的三维地震勘探技术,同时通过热力试油解决稠油开发经济评价问题,均收到显著效果。发现一大批含油圈闭,新增较大规模整装储量,该带成为河南油田“十五”乃至今后一个时期增储上产的重点地区。After 30 years of practices, the overall concept of exploration in Biyang depression had been thoroughly changed by returning back to the prolific maturing blocks in the depressions at the end of the Ninth Five-Year Plan. Further geological study shows that the shallow complex fault block reservoirs in the north slope zone have great exploration potentials because of its favorable conditions for hydrocarbon pooling. In view of the shallow burial depth and complex fault block structures in the slope zone in northern Biyang depression, 3-D seismic exploration had been adopted to preserve the shallow reflections. Apart from that, thermal testing was also implemented in the economic evaluation of heavy oil development. As a result of years of exploration in the zone,many oil-bearing traps has been discovered and reserves has been significantly increased, making the slope zone the key area for reserves and production growth in Henan oilfield for the Tenth Five-Year Plan or even longer period.
