摘要

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 off-line seismic exploration technique discussed in this paper absorbed advantages from crooked line and multi-line exploration techniques in loess plateau area,as well as the 3D seismic exploration technique,by delicately designing the off-line acquisition and maximally expanding the azimuth for the stacking trace gathers,not only the near surface dispersion and interference were avoided,but also the wide azimuth design was optimized and the off-line interference suppression effects and the static correction accuracy were raised,as a result the high fidelity and significant geology characteristics were acquired for the seismic sections.The development process and its application effects of the off-line acquisition in loess plateau area of Erdos Basin were mainly discussed in this paper.
