永利区块二维地震资料采集技术

针对宁夏永利地区影响石油地震勘探数据采集质量的主要因素,结合野外实际试验和生产资料,对表层结构调查、激发、接收等环节,进行了较深入的分析。指出采用小折射、微测井等表层结构调查方法,取全、取准表层静校正数据,对获得高品质的地震剖面至关重要;井深24-27m深度井炮激发,可以保证记录有足够的能量;对不同地表条件,采用相应的观测系统和施工方法,有利于提高资料品质,可以保证数据采集的完整性和地质任务的完成。

Seismic acquisition in the area of Yongli

Based on field test and production data this paper discussed the aspects of seismic acquisition such as near-surface investigation,shooting,receiving,and layout.It is pointed out that shallow refraction and up hole terrain investigation are vital to obtain correct static data so as to get high quality seismic section.Shooting at depth of 24-27m can ensure enough energy for seismic record.Layout and operation method should be based on surface conditions and geological task.it should be helpful for the improvement of seismic data quality.
