通过对准噶尔盆地腹部的两例高密度采集效果的分析,认为低信噪比地区要通过高密度采样技术提高资料品质,仍应该从努力提高原始资料信噪比出发。野外检波器组合仍不能被室内道组合技术完全替代,目前数字检波器在准噶尔盆地腹部地区尚不能取代模拟检波器。野外保持一定垂向组合基距小道距采集,室内进行合适的道组合,可以较好改善资料品质。 By analyzing the results of two high-density acquisitions in the belly of the Junggar Basin, it is considered that high-density sampling techniques should be used to improve the quality of data in areas with low signal-to-noise ratio. However, it is still necessary to proceed with efforts to improve the signal-to-noise ratio of the original data. Field detector combination still can not be completely replaced by the combination of indoor road technology, the current digital geophone in the Junggar Basin, the abdomen can not replace the analog detector. Field to maintain a certain vertical base spacing collection, indoor suitable road combination, you can better improve the quality of information.
