摘　　要：泌阳凹陷南部断裂带,地震地质条件复杂,属于地震勘探的困难区域。受技术条件的限制,以往地震资料品质较差,不能满足地质研究的需要,难以解决该区带复杂的地质问题。通过改善激发条件提高单炮品质,应用正演模拟技术设计科学合理的观测系统,使地震剖面的信噪比、分辨率明显提高,获得了完整的南部陡坡带资料,满足了构造解释的需要。The southern fault zone in Biyang depression is a difficult area for seismic survey due to its complex seismic -geologic conditions. The quality of previous seismic data is low due to the limitations of technical conditions, and cannot meet the requirements of geologic study and solve the complex geologic problems in this area. Through improving shooting conditions and the quality of single shot and designing scientific and rational observation systems with forward modeling technology, the signal - to - noise ratio and resolution are remarkably improved and seismic data are acquired in the whole southern steep slop zone. They can meet the requirements of structural interpreta-tioa
