摘要
敖南地区是大庆长垣外围具有较好油气开发前景的地区。以往该地区做过二维地震勘探, 由于质量品质较低, 这些资料不能满足岩性解释和识别构造圈闭的需要。结合地震生产实际, 通过理论和试验分析确定了大庆长垣外围油田勘探开发的高分辨率地震采集方法。采用CSG-40Hz高频井下检波器, 应用克浪软件进行现场施工方法的设计, 使用IMAGE数字地震仪提高接收效果, 采取有效措施解决施工中遇到的技术难题, 加强现场处理对质量的监控作用, 得到了高品质的地震剖面, 摸索出一套行之有效的大庆长垣外围地区高分辨率勘探的技术指标与施工方法。
Aonan region is one of the oil prospective areas in the periphery of Daqing Placanticline. Two-dimensional seismic prospecting have been implemented in this region in the past. Because of the low quality of the data, it cannot be applied for lithologic interpretation and structural traps identification. Considering the practice of seismic prospecting,this paper defines the data-aquisition methods for high-resolution seismic prospecting within the periphery of Daqing Placanticline through theoretical and experimental analysis.A set of practical technologies and methods for high-resolution seismic prospecting for oil exploration within the periphery of Daqing Placanticline is established.
