Applications of plane wave migration method and their effectiveness on common shot gathers and common offset gathers are also presented.
给出了平面波偏移方法在共炮点道集和共偏移距道集数据上的应用以及效果评价。
Using special common offset gather for crosshole seismic, a migration velocity analysis method is developed for crosshole seismic.
利用井间地震特有的共偏移距道集，找出了适宜于分析井间地震偏移速度的方法。
The appearances of BSRs oon near-offset profile, stacked profile, migration profile, migration profile, instantaneous amplitude profile and instantaneous phase profile are compared and described.
比较了近炮检距剖面、叠加剖面、偏移剖面、瞬时振幅剖面与瞬时相位剖面上BSR的显示特征。
The conventional velocity analysis does not consider the influence of the NMO velocity varying with offset, making the results not ideal, leading to a poor stacking and migration imaging.
由于动校正速度是随偏移距变化而变化的，而常规速度分析并没有考虑这一因素，动校正效果往往不是很理想，从而影响资料的叠加和成像效果。
