摘　　要：深化地质研究认识到泌阳凹陷南部陡坡带成藏条件好,勘探潜力大。针对该区地表起伏大,边界大断裂地震资料处理归位不准确,圈闭落实程度低等问题,在三维地震重新采集的基础上,开展地震叠前深度偏移处理和隐蔽圈闭识别技术攻关,在南部陡坡带栗园地区钻探发现一批含油圈闭,已控制石油地质储量1 740×104t。Further study of the geology in the steep slope zone of Biyang depression reveals favorable reservoiring conditions and great exploration potential. In view of the large surface relief, inaccurate positioning of the major boundary faults through seismic processing, and low ascertainment degree of traps, prestack depth migration processing and subtle trap identification are carried out by using the re-acquired 3D seismic data, leading to the discovery of several oil-beating traps with controlled geological reserves of 17.4 millions of tons in Liyuan area of southern steep slope zone.
