准噶尔盆地深层弱反射地震勘探采集方法研究

Deep Zone Weak Reflection Seismic Exploration in Junar Basin

根据在准噶尔盆地白家海地区进行的深层弱反射野外施工方法试验 ,详细介绍了该方法在准噶尔盆地野外采集中的应用。通过各种量化分析和生产实践验证 ,总结出采用高覆盖次数、长排列 ,强化炮、检组合的野外采集方法是适合准噶尔盆地深层弱反射地震勘探需要的 。

Through field operational testing on deep zone week reflection in Beijiahai Region of Junggar Basin, field acquisition of seismic exploration acquisition method is introduced in detail in the Basin. Through various quantative analysis and practical approval in production, a field acquisition method of high coverage, long array, enhanced shot position and geophone combination is summarised, it could meet the needs of seismic exploration of deep zone weak reflection in Junggar Basin. It is also point out that the method has a great significance for reference in the other operation areas.
