二维地震方法在红格尔煤田煤层气勘探中的应用
Application of 2D Seismic Method in Honger Coalfield CBM Exploration
【摘要】 红格尔煤田是新华夏系构造体系的产物,断层比较发育。在该煤田二维地震勘探中,发现部分地段存在含气异常。对该异常范围内4条测线资料进行三瞬处理(瞬时相位、瞬时频率、瞬时振幅),结合钻孔资料,解释并圈定了该煤田的含气范围。
【Abstract】 The Honger coalfield is situated in the Neocathaysian structural system,faults are well developed.During the 2D seismic prospecting,gas anomaly was found in part of certain sector.We carried out ″three instantaneous″ processing(instantaneous phase,instantaneous frequency and instantaneous amplitude) for 4 lines in the anomalous zone.Combined with drilling data,interpreted and outlined gas-bearing extent in the coalfield.
