【摘要】 YA工区高精度三维是江苏油田第一块高精度三维地震项目,工区位于高邮凹陷深凹带汉留断层东段。区域内河流分布较多、集镇村庄密集,表层地震地质条件较为复杂。对该区地震资料运用了静校正、干扰波去除、地表一致性反褶积测试、常速度扫描、精细速度分析、随机噪音衰减等处理技术,较好地解决了表层结构复杂对资料影响的问题、增强了有效信号,剖面的信噪比有明显提高。更多还原

【Abstract】 YA high precision 3D seismic aequisition is the first high precision 3D seismic project of Jiangsu oil field,the area locates at east Hanliu fault of Gaoyou depression.The high density villages and many rivers distribution make a rather complicated shooting and receiving terrain.The main processing methods for this project were statics correction,disturbance depressing,surface deconvolution,velocity scan,fine velocity analyses and random noise attenuation.These methods are good way to the complex structure of weathing layer,because the result sections are much better than before.更多还原
