摘　　要：在泌阳凹陷经过近30年的勘探,勘探难度很大的情况下,“十五”期间,通过深入开展地质研究取得新认识:①凹陷成油条件优越,是典型的“小而肥”富油凹陷;②北部斜坡带是寻找浅层复杂断块群油气藏的有利地区;③安棚深层系是寻找岩性油气藏的有利领域;④南部陡坡带是寻找多种类型复杂油气藏的有利区带。针对不同区带勘探的技术难点,加强技术攻关并采用相适的勘探技术以确保勘探目标的实现。北部斜坡带采用保护浅层反射信息的三维地震勘探技术;安棚深层系采用核磁共振测井油气层识别技术和压裂改造提高油气层产能技术;南部陡坡带采用地震叠前深度偏移处理技术,均收到显著效果。“十五”期间在泌阳凹陷新增探明储量逾6000×104t,使河南油田出现一个新的储量稳定增长时期。Biyang Depression has been explored for almost 30 years.Now it faces difficulty for further exploration.During 10th 5 Year Plan,deepening geologic investigation has been carried out and new understanding has been obtained,which include that :①it has advanced oil genetic conditions,it is a “small and rich” oil enriched depression;②the northern slope belt is a beneficial area for looking for hydrocarbon reservoirs of complex fault block groups;③Anpen deep stratum is a beneficial area for looking for lithologic reservoirs;④the southern steep slope belt is a beneficial area for looking for complex oil and gas reservoirs.In consideration of the technical problems in different blocks,it is necessary to emphase technical research and development and employ proper exploration techniques for ensuring the exploration target.In northern slope belt 3D seismic exploration technique is used to protect the shallow bed reflection information,while in Anpeng deep stratum nuclear resonance logging for recognizing oil and gas zones and fracture reconstruction technique are used to improve the productivity of the pay zones;in southern steep slope belt prestack seismic depth shift process is used.All these are used with obvious results.During 10th 5 Year Plan period,newly increased proven reserves was 6000×104t,it was a new period for reserves stabilizing and growing in Henan Oilfield.
