高精度三维地震采集技术应油田勘探开发的需要在胜利油田得到了一定的发展,形成从基本参数论证、观测系统属性分析到模型正演模拟分析一套完善的采集参数综合论证技术。激发技术采用了定向叠加震源和科学地选择激发因素的技术方法;接收方面采用提高耦合谐振的方法和使用新型的加速度检波器;压噪方面形成了一套有针对性的独特的压噪技术。通过这些技术的应用,在胜利探区的车西和田家地区取得了良好的效果。

To meet the need of the exploration and development in Shengli Oil field .High precision 3D seismic acquisition technology has been progressed fairly. It has been developed a set of completely acquisition parameters comprehensive demonstration technologies from the basic parameter demonstration though observation system attribution analysis to forward modeling. The excitation adopted the direction stacked source and the excitation factor was chosen scientifically. The receiver adopted the method of improving the coupling resonance and used the new type accelerometer; the anti￣noise aspect formed a set of anti￣noise technologies uniquely. Good effects have been achieved by applying these technologies in areas such as Chexi and Tianjia in Shengli region.
