摘要
我国西部探区地形起伏剧烈、地表类型繁多且岩性多变,为地震勘探制造了很多困难。在全面分析原始资料的基础上,在叠前完成了有针对性的静校正、能量均衡处理、多次波消除和速度场建模,有效地保证了叠前偏移地震成像质量。该项技术的研究与应用为西部探区大规模地震资料叠前偏移处理积累了经验。
In the complex western prospect the topography changes dramatically. With many kinds of terrain and complex lithologies, the seismic exploration becomes difficulty to conduct. Based on the comprehensive analysis to the raw data, the static correction, energy balance, multiple removal and velocity modeling before prestack migration were applied. The research and application of this technology has accumulated valuable experiences for the large scale prestack migration seismic data processing in the western prospect.
