本文论述的非纵地震勘探技术兼顾吸收了黄土塬沟中弯线、黄土塬多线及三维地震勘探技术的优点,通过精细设计非纵采集参数,尽最大可能展宽叠加道集方位角,不仅可避开近地表散射干扰影响,而且优化了宽方位设计,提高了黄土塬非纵噪声压制效果和静校正精度,所得成果剖面保真度较高,地质特征明显。文中重点介绍了非纵采集技术在鄂尔多斯盆地黄土塬区的发展历程与应用效果。
The non-longitudinal seismic exploration technique discussed in this paper takes into account the advantages of both the multi-line and the three-dimensional seismic exploration techniques in the loess plateau and the loess highland. By finely designing the non-longitudinal seismic acquisition parameters, the azimuth of the superimposed gathers can be broadened as much as possible Avoiding the impact of near-surface scattering interference, optimizing the wide azimuth design, improving the non-longitudinal noise suppression effect and static correction accuracy of the loess tableland, and the obtained results have higher fidelity and obvious geological features. The paper mainly introduces the development history and application effect of non-longitudinal acquisition technology in Loess Plateau of Ordos Basin.
