通过采用较小的 CMP面元、较高的覆盖次数、中频检波器接收 ,优化炮检组合 ,选用大折射—沙丘曲线法做静校正 ,应用动静校正迭代、高精度速度分析等方法和技术进行处理 ,首次在准噶尔盆地大沙漠区获得了高信噪比、高分辨率的三维地震资料。目的层侏罗系 (2 .0～ 3.0 s)有效频宽达 10～ 90 Hz,主频 5 0 Hz。资料解释新发现了 17条小断层 (断距 10～ 2 0 m)。经大量井资料证实 ,高分辨率三维资料精度高。
By using a smaller CMP panel, a higher number of coverage, IF receiver to receive, optimize the gun combination, the choice of large refraction - sand dune curve method for static correction, the application of static and dynamic correction iteration, high-precision speed analysis methods and techniques For the first time, 3D seismic data with high signal-to-noise ratio and high resolution have been obtained in the large desert area of Junggar Basin. In Jurassic (2.0 ~ 3.0 s), the effective bandwidth reaches 10 ~ 90 Hz and the dominant frequency is 50 Hz. Data interpretation found 17 new faults (10 ~ 20 m apart). After a large number of well data confirmed, high-resolution three-dimensional data with high accuracy.
