【摘要】 针对无检波器组合的单点高密度地震数据,应用数值模拟和实际地震数据的处理试验和理论分析发现:(1)室内组合可以相对有效地压制随机干扰和面波;(2)室内组合可以在静校正之后进行,这样有利于同相叠加和频带的保持;(3)组合对地震主频有损伤,且组合道距越大,主频降低越明显;(4)在保证信噪比的前提下,无组合更有利于高分辨率地震勘探.更多还原

【Abstract】 To the Q-Land seismic data,it is found by numerical modelling,field seismic data process testing and theoretical analysis that:(1) Indoor combination can suppress random noise and surface wave comparative effectively; (2) Indoor combination after static correction could keep the frequency band because of the same phase stacking;(3) Combination will cause damage to the main frequency,which decreases more apparently along with the bigger combination trace interval and (4) Under the condition of good signal-to-noise ratio,none-combination is more favorable to the high resolution seismic exploration.更多还原
